Training Methods
|
The lead Instructor will begin this session by welcoming
the participants to Unit 3: Disaster Medical Operations—Part 1, and will
introduce the Instructors for the session. The Instructor will then provide
an overview of the topics included in the unit: Treatment of
life-threatening conditions that may be encountered (airway obstruction,
bleeding, and shock) and conducting triage.
Next, the Instructor will discuss and demonstrate the immediate procedures
required for opening the airway, controlling bleeding, and treating shock.
The participants will have the opportunity to practice techniques for
treating each of these conditions. During this period, some discussion will
take place about the differences between disaster medical operations and the
participants’ image of everyday first aid. (For example, mouth-to-mouth
resuscitation and cardiopulmonary resuscitation (CPR) lose some of their
importance in disaster situations when there are multiple casualties needing
immediate attention and limited resources.)
The
next topic of this session will deal with triage. The Instructor will open
with a discussion of the meaning and goal of triage and provide background
from the military’s experience using triage for prioritizing treatment in
multicasualty situations. This background will lead to comparisons of
triage in disaster circumstances and the steps that CERT members will follow
when conducting triage.
Finally, the participants will practice triage evaluation and immediate
treatment in a simulated multicasualty exercise. This exercise will
illustrate the need to conduct triage effectively and expeditiously under
pressure and to focus on rescuer safety.

Remarks
|
Be sure to emphasize
throughout the session the importance of rescuer safety (e.g., using safety
equipment, working with a buddy, and doing a thorough sizeup). These points
cannot be made too often or too strongly. CERT members cannot help anyone
if they become victims.
|
Unit 3: Disaster Medical Operations—Part 1
|
|
|
Introduction and Unit
Overview
|
|

|
Introduce Unit
|
|
Introduce this unit by welcoming the participants to Unit 3 of the CERT
training program.
Introduce the new instructors for this unit and ask each to describe briefly
his or her experience in medical operations.
|
|
|
|
|
Briefly review the fire safety lessons, covering the key points listed
below.
§
There are different classes of fire, and the method used to
extinguish each must be appropriate for the type of fire.
§
Before making the decision to extinguish a fire, CERTs should
complete a thorough sizeup.
§
CERTs should never attempt to enter smoke-filled buildings and
should never attempt to extinguish large fires.
§
Hazardous materials can be stored or transported and are common in
both the home and workplace. CERT members should ensure that hazardous
materials in the home are stored (or discarded) properly. In a disaster
situation, CERTs should treat hazardous materials placards as a stop sign.
Answer any questions that the students may have about fire safety. Then,
continue with the session.
|
|

|
Explain Assumptions
|
|
Explain that the need for disaster medical operations is based on two
assumptions:
§
The number of victims will exceed the local capacity for treatment.
§
Survivors will assist others. They will do whatever they know how to
do. They need to know lifesaving first aid or post-disaster survival
techniques.
|
|
|
|
Introduction and Unit
Overview (Continued)
|
|
|
|
|
Emphasize the need for neighborhood-level medical operations by describing
the three phases of death from trauma:
§
Phase 1:
Death within minutes as a result of overwhelming and irreversible damage to
vital organs
§
Phase 2:
Death within several hours as a result of excessive bleeding
§
Phase 3:
Death in several days or weeks as a result of infection or multiple-organ
failure (i.e., complications from the injury)
|
|

|
Instructor’s Note
|
|
|
Explain that these phases underlie why
disaster medical operations are conducted as they are (by identifying those
with the most serious injuries as soon as possible and treating those with
life-threatening injuries first). |
|
|
|
|
|
Point out that Peter Safer’s research after earthquakes in Chile, Peru, and
Italy indicated that more than 40 percent of disaster victims in the second
and third phases of death could be saved by providing simple medical care.
|
|
|
|
|
Add
that CERT personnel are trained to provide:
§
Treatment for life-threatening conditions—airway obstruction,
bleeding, and shock—and for other less urgent conditions.
§
The greatest good for the greatest number of victims by conducting
simple triage and rapid treatment.
|
|
|
|
|
Remind the group that, in a disaster there will be more victims than
rescuers and that immediate help will not be available to function quickly
and efficiently to save lives.
Introduce the concept of Simple Triage And Rapid Treatment (START) when
initially dealing with casualties in a disaster.
Poll
the group to see how many have taken first aid courses.

|
Instructor’s Notes
|
|
|
Note that those who have taken first aid courses will
need to understand that CERT covers disaster medical operations where time
is critical to conduct triage and treat many victims. CPR is not taught in
this course because it is labor-intensive and not appropriate when there are
many victims and professional help will be delayed. |

the end of this unit, they should be able to:
§
Identify the “killers.”
§
Apply techniques for opening the airway, controlling bleeding, and
treating for shock.
§
Conduct triage under simulated disaster conditions.
Stress once more that the goal of disaster medical operations is to do the
greatest good for the greatest number. In a disaster with many victims,
time will be critical. CERT members will need to work quickly and
efficiently to help as many victims as possible.

|
|
|
Reiterate that this session will introduce the participants to treating the
“three killers” and the principles of triage. Tell the group that,
throughout the unit, they will have opportunities to practice the treatment
techniques and, at the end of the unit, they will have the opportunity to
conduct triage evaluations in a simulated disaster.
|
|

|
Instructor’s Note
|
|
|
Ask the participants if anyone has any questions. |

|
Introduce Topic
|
|
Tell
the group that, in emergency medicine, airway obstruction, bleeding, and
shock are “killers.” The first priority of medical operations is to attend
to those potential killers by:
§
Opening the airway.
§
Controlling excessive bleeding.
§
Treating for shock.
Explain that this section will train the group to recognize the “killers” by
recognizing their symptoms and their effects on the body.

Remind the participants to wear safety equipment: Helmet, goggles, gloves,
mask, and boots. Tell them that a time-saving technique is to wear latex
gloves under their work gloves. Then, when they find a victim, they can
remove their work gloves and are ready to work with the victim.
|

Ask Question
|
|
|
Does anyone know what the most common airway obstruction is? |
|
|

|
PM, P. 3-4
|
|
If
not mentioned, tell the group that the most common airway obstruction is the
tongue. Refer the participants to the illustration titled, Airway
Obstructed by the Tongue, in the Participant Manual. Explain that, in
an unconscious or semiconscious victim, especially one positioned on his or
her back, the tongue—which is a muscle—may relax and block the airway. A
victim with a suspected airway obstruction must be checked immediately for
breathing and, if necessary, the airway must be opened.
|
|

|
PM, P. 3-4
|
|
Explain that when an airway obstruction is suspected, CERT members should
clear the airway using the Head-Tilt/Chin-Lift method. Refer the
participants to the table titled, Head-Tilt/Chin-Lift Method for Opening
an Airway, in the Participant Manual.

Instructor’s Notes
|
|
|
Demonstrate each step slowly using an instructor or
participant as the victim. Explain that proper technique is important, but
so is speed if there are multiple victims. Be sure to wear gloves while
demonstrating to reinforce the need for protective equipment.
Explain that this method causes little or no
cervical-spine manipulation because only the head is manipulated. |
|
|
|
|
|
This
method involves the following seven steps:
§
Step 1:
Positioning one’s self at an arm’s distance, shake the victim and shout,
“Can you hear me?”
§
Step 2:
If the victim does not or cannot respond, place the palm of one hand on the
victim’s forehead.
§
Step 3:
Place two fingers of the other hand under the chin and tilt the jaw upward
while tilting the head backward slightly.
§
Step 4:
Place your ear over the victim’s mouth, looking toward the victim’s feet,
and place a hand on the victim’s abdomen.

Exercise: Opening
the Airway
|
|

|
Conduct Exercise
|
|
Purpose:
This exercise allows the participants to practice using the
Head-Tilt/Chin-Lift method on each other. It is important to have other
instructors who can help observe. Make sure that you all agree on the
proper procedure.
Instructions:
Follow the steps below to conduct this exercise:
|
|
|
|
|
1.
Assign the
group to pairs.
2.
Ask the
person on the right to be the victim and the person on the left to be the
rescuer.
3.
Ask the
victims to lie on the floor on their backs and close their eyes.
4.
Ask the
rescuer to use the Head-Tilt/Chin-Lift method on the victim to open the
airway.
|
|

|
Instructor’s Note
|
|
|
Observe each group and correct improper technique. |
|
|
|
|
|
5.
After the
rescuer has made two or three attempts at using the Head-Tilt/Chin-Lift
method, ask the victim and the rescuer to change roles.
6.
Allow each
rescuer two or three observed attempts to use the Head-Tilt/Chin-Lift
method.
|
|
|
|
|
After all of the participants have had the opportunity to be the rescuer,
discuss any problems or incorrect techniques that were observed. Explain
how to avoid these problems in the future.
|
|
|
|
|
Treating
Life-Threatening Conditions (Continued)
|
|

|
Instructor’s Note
|
|
|
Teach this skill in accordance with your local protocols. |
|
|
|
|
|
Remind the participants that part of their mission is to do the greatest
good for the greatest number of people. For that reason, if breathing is
not restored on the first try using the Head-Tilt/Chin-Lift method, CERT
members should try again using the same method. If breathing cannot be
restored on the second try, CERT members must move on to the next victim.
|
|
|
|
|
Tell
the group that, if breathing has been restored, the airway still must be
maintained. One option is to use a volunteer or walking wounded to hold the
head in place. The airway also can be maintained by placing soft objects
under the victim’s shoulders to elevate the shoulders slightly and keep the
airway open.
|
|

|
Instructor’s Notes
|
|
|
Demonstrate both techniques.
Ask the participants if anyone has any questions
about recognizing and clearing airway obstructions. |
|
|
|
|
|
Tell
the group that they should always be concerned with head, neck, or spinal
injuries (all of which are common in structural collapses). Used properly,
the head-tilt/chin-lift method for opening an airway causes little spinal
manipulation because the head pivots on the spine.
Remind the group of the importance of opening the airway as quickly as
possible.
Tell
the participants that in the next section, they will learn to recognize and
treat uncontrolled bleeding.
|
|

|
Instructor’s Note
|
|
|
Explain that head injury refers to concussion, not
head or facial cuts, although these may be indicators of head injury. |

|
Controlling Bleeding
|
|

|
Introduce Controlling
Bleeding
|
|
Introduce this section by telling the group that uncontrolled bleeding
initially causes weakness. If bleeding is not controlled, the victim will
go into shock within a short period of time, and finally will die. An adult
has about five liters of blood. Losing one liter can result in death.
|
|

|
Instructor’s Notes
|
|
|
Show the class a one-liter bottle to illustrate this
learning point. |
|
|
|
|
Explain to the group that there are three types of bleeding and the type can
usually be identified by how fast the blood flows:
§
Arterial bleeding. Arteries transport blood under high pressure.
Bleeding from an artery is spurting bleeding.
§
Venous bleeding. Veins transport blood under low pressure. Bleeding from a vein is
flowing bleeding.
§
Capillary bleeding. Capillaries also carry blood under low pressure.
Bleeding from capillaries is oozing bleeding.
|
|
|
|
|
Tell
the group that there are three main methods for controlling bleeding:
§
Direct pressure
§
Elevation
§
Pressure points
|
|

|
PM, PP. 3-7
|
|
Refer the participants to the table titled, Procedures for Controlling
Bleeding, in the Participant Manual.

Procedures |
|
Direct Pressure |
§
Place direct pressure over the wound by putting a clean dressing over
the wound and pressing firmly.
§
Maintain pressure on the dressing over the wound by wrapping the
wound firmly with a pressure bandage. |
|
Elevation |
§
Elevate the wound above the level of the heart. |
|
Pressure Points |
§
Put pressure on the nearest pressure point to slow the flow of blood
to the wound. Use the:
 |
Brachial point for bleeding in the arm. |
 |
Femoral point for bleeding in the leg. |
(Page 3-8 in the Participant Manual contains
illustrations of these pressure points.)
There
are other pressure points that the Instructor may demonstrate. |
|
|
|
|
Treating
Life-Threatening Conditions (Continued)
|
|
|
|
|
Explain to the group that direct pressure combined with elevation will
address most bleeding. Demonstrate the procedure for controlling bleeding
through direct pressure:
§
Step 1:
Place direct pressure over the wound by putting a clean dressing over the
wound and pressing firmly.
§
Step 2:
Maintain pressure on the dressing over the wound by wrapping firmly
with a pressure bandage.
|
|
|
|
|
Stress that direct pressure and elevation can take 5 to 7 minutes to stop
the bleeding completely. The use of a dressing and pressure bandage allows
the rescuer to move on to the next victim.
Explain that a pressure bandage should be tied with a bow, so that it can be
loosened—rather than cut—to examine the wound, and then retied. This
procedure helps to conserve supplies and saves time.
|
|

|
Instructor’s Note
|
|
|
Explain that the bandage maintains the direct
pressure needed to stop the bleeding. CERT members continue to assess the
victim’s status. If the victim’s limb is turning blue or becoming numb
below the bandage, then it should be loosened. |
|
|
|
|
|
Ask
if anyone has any questions about applying a pressure bandage.
Demonstrate the procedure for controlling bleeding through elevation:
Elevating the wound above the level of the heart. Elevation is used in
combination with direct pressure.
|
|
|
|
|
Tell
the participants that there are also pressure points that can be used to
stem the flow of bleeding.
|
|
|

Exercise:
Controlling Bleeding
|
|

|
Conduct Exercise
|
|
Purpose:
This exercise allows the participants to practice the techniques for
controlling bleeding on each other.
Instructions:
Follow the steps below to conduct this exercise:
|
|
|
|
|
1.
Assign the
group to pairs.
2.
Ask the
older person to be the victim and the younger person to be the rescuer.
3.
Ask the
victims to lie on the floor on their backs and close their eyes.
|
|
|
|
|
4.
Ask the
rescuer to use direct pressure to control bleeding from a simulated wound on
the right forearm just below the elbow. Have the rescuer:
§
Apply a pressure bandage.
§
Elevate the arm.
§
Repeat these two steps.
§
Repeat the two steps for speed.
|
|

|
Instructor’s Note
|
|
|
Observe each group and correct any improper
techniques. Common errors include bandages that are too loose, tying a knot
instead of a bow, or elevation that cannot be maintained with comfort. |
|
|
|
|
|
5.
After the
rescuer has made at least three attempts at using each technique, ask the
victim and the rescuer to change roles. (Note: The three attempts should
emphasize a progression of slow to fast in applying the skill.)
|
|
|
|
|
6.
Allow each
rescuer at least one observed attempt to use each technique.
After all of the participants have had the opportunity to be the rescuer,
discuss any problems or incorrect techniques that were observed. Explain
how to avoid the problems in the future.
|
|
|
|
|
Treating
Life-Threatening Conditions (Continued)
|
|

|
Instructor’s Note
|
|
|
Demonstrate use of the brachial pressure point by
applying pressure to your own arm. Then, have the participants apply
pressure to their own arms so that they can feel the effect of this method. |
|
|
|
|
|
Note: The following section on tourniquets is optional and can
be added at the Instructor’s discretion.
In a
disaster setting, especially following an earthquake, response resources
will be delayed in meeting many immediate needs. CERTs will use direct
pressure/elevation and pressure points to manage most bleeding. However, if
bleeding cannot be stopped using these methods and professionals will be
delayed in responding, a tourniquet may be a viable option to save a person
from bleeding to death.
|
|
|
|
|
A
tourniquet is a last resort (life or limb) when other means have failed to
control bleeding in an arm or a leg. While the use of a tourniquet is
extremely rare, it may have a use when part of an extremity is amputated or
crushed and bleeding cannot be stopped by any other preferred means.
|
|
|
|
|
Explain the proper use of a tourniquet and demonstrate its application,
making the following points.
§
A tourniquet is a bandage which, when placed around a limb and
tightened, cuts off the blood supply to the part of the limb beyond it.
§
A tourniquet can do harm to the limb, but it can halt severe blood
loss when all other means have failed and professional help will not arrive
in time to help stop the bleeding before the person dies.
§
Use any long, flat, soft material (bandage, neck tie, belt, or
stocking). Do not use materials like rope, wire, or string, that can cut
into the patient’s flesh.
|
|
|
|
|
Treating
Life-Threatening Conditions (Continued)
|
|
|
|
|
§
General rules for using a tourniquet include:
 |
Place the tourniquet between the wound and the heart. |
 |
Use wide and soft material. |
 |
Tie a knot and using a stick, pen, ruler, etc., as a lever, tighten the
bandage until bleeding stops, and secure the lever to maintain pressure. |
 |
Mark the patient is a way that will inform first responders that a
tourniquet was used and what time it was applied. |
 |
Only proper medical authorities can remove a tourniquet. |
|
|
|
|
|
Reiterate the three main
ways to control excessive bleeding:
§
Direct pressure
§
Elevation
§
Pressure points
Stress that bleeding must be controlled as quickly as possible so as not to
endanger the victim’s life from blood loss. A tourniquet may be used only
as a last resort.
Remind the group that they should always wear their latex gloves, goggles,
and a mask as a protection against blood-borne pathogens, such as hepatitis
and HIV.
|
|

|
Ask Question
|
|
|
Ask if anyone has any questions about controlling excessive bleeding. |
|
|
|
|
|
Tell
the group that the next section will deal with recognizing and treating
shock.
|
|
|
|
|
Treating
Life-Threatening Conditions (Continued)
|
|
|
|
|
Recognizing and
Treating Shock
|
|

|
Introduce Recognizing
and Treating Shock
|
|
Introduce this section by explaining that shock is a disorder resulting from
ineffective circulation of blood. Remaining in shock will lead to the death
of:
§
Cells.
§
Tissues.
§
Entire organs.
Stress that the body will initially compensate for blood loss and mask the
symptoms of shock. Stress the importance of continually evaluating patients
for shock and monitoring their condition.
|
|
|
|
|
Tell
the group that the main signs of shock that CERT members should look for
are:
|
|
|
|
|
§
Rapid and shallow breathing.
§
Capillary refill of greater than 2 seconds.
§
Failure to follow simple commands, such as “Squeeze my hand.”
|
|

|
Instructor’s Note
|
|
|
To demonstrate rapid, shallow breathing, ask two
participants to come to the front of the room. Tell one to breathe
normally. Tell the other to “pant” (i.e., 30 or more breaths per minute).
Point out the audible difference to the class. Make sure that the
participant who is “panting” is sitting during the demonstration. |
|
|
|
|
Ask
the participants to check their own capillary refill by pushing down on the
palm of their hand and then releasing. Tell them to watch what happens.
Ask one of the participants to explain. Tell the group that this is
referred to as the “blanch test.”

Demonstrate the procedure for treating victims of shock. Refer the
participants to the chart titled, Procedures for Controlling Shock,
in the Participant Manual.
§
Step 1:
If necessary, place a blanket or other material under the victim to provide
protection from extreme ground temperatures (hot or cold). Position the
victim on his or her back. Elevate the feet 6-10 inches above the level of
the heart. Maintain an open airway.
§
Step 2:
Control obvious bleeding.
§
Step 3:
Maintain body temperature.
§
Step 4:
Avoid rough or excessive handling.
|
|

|
Ask Question
|
|
|
Ask if anyone has a question about the signs or treatment of shock. |
|
|
|
|
|
Emphasize that, although victims who are suffering from shock may be
thirsty, they should not eat or drink anything initially because they
may also be nauseated.

Exercise: Treating
Shock
|
|

|
Conduct Exercise
|
|
Purpose:
This exercise allows the participants to practice the
steps for treating shock on each other.
Instructions:
Follow the steps below to conduct this exercise:
|
|
|
|
|
1.
Assign the
group to the same pairs as in the previous exercises.
2.
Ask the
person who was the rescuer first in the last exercise to be the victim
first.
3.
Ask the
victims to lie on the floor on their backs and close their eyes.
|
|
|
|
|
4.
Explain the
following scenario to the rescuers:
§
You have come upon this victim who has been bleeding profusely from a
wound of the upper arm for an undetermined period of time.
§
The victim is now unconscious.
5.
Ask the
rescuer to treat the victim.
|
|

|
Instructor’s Note
|
|
|
Observe each rescuer as he or she treats for shock.
Do not let the students put a blanket under the victim’s feet.
Blankets are scarce during a disaster response and should not be used for
nonessential purposes. |
|
|
|
|
|
6.
When each
rescuer has been observed treating for shock, ask the victim and the rescuer
to switch roles.
When
all of the rescuers have had the opportunity to treat their victims, lead a
discussion about any incorrect techniques observed and how to correct them
in the future.
|
|
|
|
|
Reiterate the key points about recognizing and treating shock:
§
A victim may display one or more signs of shock.
§
If there is any reason to suspect shock, apply immediate treatment.
|
|
|

Ask Question
|
|
|
Ask if anyone has a question about the signs of shock or its
treatment. |
|
|
|
|
|
|
|
|
|
|
Tell
the group that, in a disaster scenario, they may have many victims requiring
attention and few resources to use. The next section will use the skills
just learned for prioritizing victim treatment, called triage.
|
|
|
|
|
Triage
|
|

|
Introduce Topic
|
|
Introduce this topic by asking the group how many remember the scenes from
the television series M*A*S*H where the helicopters arrived and the
doctors and nurses quickly examined each patient to determine the priority
for treatment.
|
|

|
Instructor’s Note
|
|
|
The point of this discussion is to get the
participants thinking about multiple casualties. |
|
|
|
|
|
During these scenes, the medical personnel:
§
Identified the dead and those who were too severely injured to be
saved.
§
Sent those with relatively minor injuries and wounds to a holding
area to await treatment.
§
Identified those who would die without immediate treatment and sent
them to the operating room.
Tell
the participants that these scenes showed medical personnel conducting
triage—a French term meaning “to sort.”
Explain that during triage, victims are evaluated, sorted by the urgency of
the treatment needed, and set up for immediate or delayed treatment.
|
|
|
|
|
Explain further that triage was, in fact, initiated by the military and that
experience has shown that triage is an effective strategy in situations
where:
§
There are many more victims than rescuers.
§
There are limited resources.
§
Time is critical.
|
|
|
|
|
Triage (Continued)
|
|

|
Instructor’s Note
|
|
|
Remind the group that, if hazardous materials are
present or if the incident involves a chemical or biological terrorist
attack, rescuer safety is paramount. CERT members should leave the scene to
avoid harm to themselves, and to reduce the risk of spreading the
contamination. |
|
|
|
|
|
Point out that triage occurs as quickly as possible after a victim is
located or rescued.

|
|
During triage, victims’ conditions are evaluated and the victims are
prioritized into three categories:
§
Immediate (I): The victim has life-threatening (airway, bleeding, or shock)
injuries that demand immediate attention to save his or her life; rapid,
life-saving treatment is urgent.
§
Delayed (D): Injuries do not jeopardize the victim’s life. The victim may
require professional care, but treatment can be delayed.
|
| |
|
|
|
|
|
|
|
|
|
|
|
Triage (Continued)
|
|
|
|
|
§
Dead (DEAD): No respiration after two attempts to open the airway. Because CPR
is one-on-one care and is labor-intensive, CPR is not performed when there
are many more victims than rescuers.
Remind the group that the CERT program goal is to do the greatest good for
the greatest number.
|
|

|
Instructor’s Note
|
|
|
Some participants may respond negatively to not
performing CPR. Explain that CPR is a maintenance therapy that requires
time and rescuers that may not be available when dealing with multiple
casualties after a disaster. In the event that multiple casualties are
not encountered, CPR may be administered by available trained personnel. |
|
|
|
|
|
Explain that, from triage, victims are taken to the designated medical
treatment area (immediate care, delayed care, or the morgue).
|
|

|
Instructor’s Note
|
|
|
Emphasize the need for rescuer safety during triage. Rescuers must
wear all safety equipment, including latex gloves, goggles, a helmet, and a
dust mask (preferably one labeled, “N95,” which will filter particles as
small as 3 microns) when examining victims and should try to change gloves
between victims. Because of limited supplies, it may not be possible to use
a new pair of gloves for every victim. If this is the case, gloves may be
sterilized between treating victims using 1 part bleach to 10 parts water.
Tell the group that their disaster kits should have a box of latex gloves.
Demonstrate the methods for changing latex gloves without
contaminating oneself by pinching the glove at the top and rolling it off
while turning it inside out as it comes off. To remove the second glove,
tuck two fingers inside the glove and roll the glove off, being careful not
to touch the outside. |

Triage in a Disaster
Environment
|
|

|
Introduce Triage in a
Disaster Environment
|
|
Introduce this section by explaining the general procedure for conducting
triage:
§
Step 1: Stop, Look, Listen, and Think.
Before you start, stop and size up the situation by looking around and
listening. THINK about your safety, capability, and limitations, and decide
if you will approach the situation and how.
|
|
|
|
|
§
Step 2: Conduct voice triage.
Begin by calling out, “Emergency Response Team. If you can walk, come to
the sound of my voice.” If there are survivors who are ambulatory, instruct
them to remain at a designated location, and continue with the triage
operation. (If rescuers need assistance and there are ambulatory survivors,
then these survivors should be asked to provide assistance.) These persons
may also provide useful information about the location of the victims.
§
Step 3: Start where you stand, and follow a
systematic route.
Start with the closest victims and work outward in a systematic fashion.
§
Step 4: Evaluate each victim and tag them “I” (immediate), “D”
(delayed), or DEAD. Remember to evaluate the walking wounded.
§
Step 5: Treat I victims immediately.
Initiate airway management, bleeding control, and/or treatment for shock for
Category I victims.
|
|
|
|
|
§
Step 6: Document triage results for:
·
Effective deployment of resources.
·
Information on the victims’ locations.
·
A quick record of the number of casualties by degree
of severity.
Emphasize that the rescuer’s safety is paramount during triage. Remind the
participants to wear proper protective equipment so as not to endanger their
own health.

Performing a Triage
Evaluation
|
|

|
Instructor’s Note
|
|
|
The goal of this activity is to complete triage in 15 to 30 seconds.
Each student should repeat these tasks three times, progressing from slow to
fast. |
|
|
|
|
|
|
|

|
Introduce Triage
Evaluation
|
|
Refer the
participants to the table titled, Triage Procedures, in the
Participant Manual. The goal of triage is to identify and treat victims who
need immediate care as rapidly as possible. Introduce this section
explaining that when conducting a triage evaluation, they should:
|
|

|
PM, P. 3-15
|
|
§
Start with the airway.
Positioning oneself at an arm’s distance, shake the victim and shout. If
the victim does not respond, then:
·
Position the airway.
·
Look, listen, and feel.
·
Check breathing (greater than 30 should be marked “I”).
·
If the victim is not breathing after two attempts to
open the airway, then tag the victim “DEAD.”
|
|
|
|
|
§
Check for bleeding.
·
Stop uncontrolled bleeding.
·
Perform blanch test (greater than 2 seconds should be
marked “I”).
|
|

|
Instructor’s Note
|
|
|
Explain that the blanch
test is not valid in children, and that mental status should be used instead
as the main indicator. |
|
|
|
|
|
§
Check mental status. Ask the victim to follow a
simple command (such as squeezing your hand). If no response, the victim’s
status is “I.”
If
the victim passes all tests, his or her status is “D.” If the victim
fails one test, status is “I.” Remember that everyone gets a tag.
|

|
PM, P. 3-15
|
Triage Procedures |
|
Step |
Procedures |
|
1 |
Check airway/breathing. At an arm’s distance, shake the
victim and shout. If the victim does not respond:
§
Position the airway.
§
Look, listen, and feel.
§
Check breathing rate. Abnormally rapid respiration (above 30 per
minute) indicates shock. Treat for shock and tag “I.”
§
If below 30 per minute, then move to Step 2.
§
If the victim is not breathing after 2 attempts to open airway, then
tag “DEAD.” |
|
2 |
§
Check circulation/bleeding.
§
Take immediate action to control severe bleeding.
§
Check circulation using the blanch test (for capillary refill).
 |
Press on an area of skin until normal skin color is gone. A good place to
do this is on the palm of the hand. The nailbeds are sometimes used.
|
 |
Time how long it takes for normal color to return. |
§
Treat for shock if normal color takes longer than 2 seconds to
return, and tag “I.” |
|
3 |
Check mental status. Give a simple command, such as “Squeeze my hand.”
Inability to respond indicates that immediate treatment for shock is
necessary. Treat for shock and tag “I.” |

how to document victims during triage (the number of people tagged
“Immediate,” “Delayed,” and “Dead”) and their location. Also explain to the
group how useful such information can be to professional responders.

out that “2 seconds” refers to the results of the capillary refill test.)
|
|
|
|
|
Stress that time will be critical in a disaster. The participants will not
be able to spend very much time with any single victim.
Stress also that the participants should take advantage of local exercises
as a means of maintaining their triage skills and to help them avoid the
triage pitfalls.

Exercise: Conducting
Triage
|
|

|
Conduct Exercise
|
|
Purpose:
This
exercise is intended to allow the participants to practice conducting triage
in a high-pressure situation.
Instructions: Follow the steps below to conduct this
exercise:
1.
Before
the session, prepare six cards, each documenting the status of one disaster
victim, as follows:
§
Victim #1: Ambulatory—responds to voice triage.
Minor bleeding.
Normal blanch.
§
Victim #2: Bleeding extremity.
Unconscious.
After two attempts to open airway, still not
breathing.
|
|
|
|
|
§
Victim #3: Standing, but does not respond to
voice commands.
§
Victim #4: No signs of bleeding.
Unconscious.
Blanch takes 5 seconds.
|
|
|
|
|
§
Victim #5: No bleeding.
Conscious.
Doesn’t squeeze hand when asked.
§
Victim #6: Minor bleeding.
Conscious but disoriented.
Breathing rate is 40 per minute.
|
|
|
|
|
2.
Assign
the class to 6-person groups. Have enough sets of cards so that there will
be one set for each group. In each group, three participants will act as
victims, and three will act as search and rescue team members (two rescuers
and one runner).
3.
Ask the
“victims” to select a card from their set and tape it to their shirts.
4.
Designate a
“disaster” area for each group and ask the victims to arrange themselves
within the designated area.
|
|
|
|
|
Triage (Continued)
|
|

|
Instructor’s Note
|
|
|
Remind the participants to bring their blankets to the disaster area. |
|
|
|
|
|
5.
Explain
to the participants that the three “rescuers” will have 5 minutes to:
§
Conduct triage on each of the victims and determine how each should
be tagged and treated.
§
Document the number of victims in each category of triage (immediate,
delayed, dead).
|
|
|
|
|
6.
Begin the
activity. Observe the rescuers as they plan for and conduct triage.
7.
At the
end of the time period, call the groups together and conduct a 5-minute
discussion with each group on the results of the triage exercise. Discuss:
§
Problems that the rescuers encountered during triage.
§
How it felt to be under pressure to conduct triage
within such a short period of time.
Relate the rescuers’ feelings about their time constraints to the pressure
they will feel under actual conditions. Explain that they will learn ways
to control some of their stresses in a later session.
8.
Have the
group members switch roles and repeat the activity, with the three new
victims using the three unused cards, so that each participant has a chance
to be a rescuer once.
|
|

|
Instructor’s Notes
|
|
|
Ask the
participants if they have any questions about triage.
Be sensitive to the participants and the difficulty of these
decisions during a catastrophic event. Emphasize that planning and
organization are necessary to do the greatest good for the greatest number
of victims. |

Unit Summary
|
|
 |
Summarize the Key
Points
|
|
Summarize
the key points from this unit:
§
CERT members’ ability to open airways, control
bleeding, and treat shock is critical to saving lives.
·
Use the Head-Tilt/Chin-Lift method for opening
airways.
·
Control bleeding using direct pressure, elevation,
and/or pressure points.
·
If there is a question about whether a victim is in
shock, treat for shock.
§
Triage is a system for rapidly evaluating victims’
injuries and prioritizing them for treatment. The procedure for conducting
triage evaluations involves checking:
·
The airway and breathing rate.
·
Circulation and bleeding.
·
Mental status.
Remind the participants that disaster medical operations require careful
planning, teamwork, and practice. Urge them to take advantage of
participating in community-wide disaster exercises whenever they are
scheduled.
|
|
|
|
|
Homework Assignment
|
|
|
|
|
Ask the
participants to read and become familiar with Unit 4: Disaster Medical
Operations— Part 2 before the next session.
Remind
the participants to bring a blanket, roller gauze, adhesive tape, and
cardboard to the next session.
Thank everyone for attending this session.
