EMERGENCY
ACTION PRINCIPLES; DO
THE PRIMARY SURVEY OF VICTIM
The
primary survey (initial or rapid assessment) is a methodical process used to
quickly identify immediate life threatening injuries and conditions that
require intervention without delay. The primary survey should be completed
promptly upon initial patient contact if
no immediate life threatening injuries and conditions requiring intervention
are found during the survey. The primary survey should only be interrupted
when:
1. life
threatening condition is identified and immediate life saving interventions are
initiated
2. the
scene conditions require that the patient be moved immediately due to danger to
EMS personnel or the patient
The
purpose of a primary survey is to check the life threatening conditions and to
give urgent first aid care.
The primary survey of the victim can be done with:
1.
Check
for Consciousness
You
may or may not know the cause of unconsciousness if you discover an unconscious
victim. Unconsciousness can have many causes including:
·
Injuries, especially
head injuries
·
Illness or severe
infection
·
Blood loss and shock
·
Poisoning
·
Severe allergic
reaction
·
Diabetic reaction
·
Heat exhaustion
·
Fatigue
·
Stress
Checking Level of
Consciousness
·
There is a difference
between fainting and unconsciousness. Both conditions can have the same causes,
however fainting is usually much LESS serious than a state of unconsciousness. Most
people who faint recover quickly when laying down.
·
If a victim appears
unconscious, tap him/her gently but firmly on the shoulder and ask “Are you
okay?” If you do not get a response,
then your next step will be to check the victim’s Airway, Breathing and
Circulation (pulse). We call this step
the ABC’s.
·
It is important to
check airway and breathing whenever you find an unconscious victim. This is because a blocked airway or no
breathing will cause a victim to become unconscious due to the victim not
getting needed oxygen into the body.
·
To check the ABC’s, the
victim should be lying on his/her back, on a firm, flat surface. If the victim is lying crumpled or face down,
you will need to re-position the victim onto his/her back. We will cover this procedure later. Since “not breathing” is life threatening,
moving the victim may be necessary in order to save a life.
2.
Explain
and Demonstrate ABCs:
A
is Airway
Your
first step is A - the airway. The airway
is the passage through which air (oxygen) travels to the lungs when we breathe.
If a victim’s airway is blocked, oxygen cannot reach the lungs and death will
soon follow. If a victim is talking,
crying and/or coughing, then he/she is getting SOME air through the airway.
An
airway can be blocked by the tongue when a victim is lying on his/her
back. In fact, the tongue is the most
common cause of a blocked airway in an unconscious person. When you encounter an unconscious victim, it
is critical that you open the airway.
There are 2 methods which you can use.
Either method will lift the tongue away from the back of the throat and
make breathing possible again.
a) The
Head Tilt / Chin Lift (demonstrate technique on a volunteer or mannequin if
available)
·
Place one hand on the
victim’s forehead and apply firm (but gentle), backward pressure with the palm
to tilt the head back.
·
Place one or two
fingers of the other hand (use one finger for an infant) under the bony part of
the lower jaw near the chin and lift to bring the chin forward.
·
Do NOT press the
fingers into the soft tissue under the chin. This may block the airway.
·
Do NOT use the thumb
for lifting the chin.
·
Do NOT close the
victim’s/infant’s mouth completely.
b) Jaw
Thrust Technique (demonstrate technique on a volunteer or mannequin if
available)
·
Use this technique if
head or neck injury is suspected.
·
Sit at the victim’s
head facing the length of the body.
·
Rest your elbows on the
same surface on which the victim is lying.
·
Grasp the bony part of
the victim’s lower jaw and lift with both hands, one on each side.
After
you open the airway using one of the methods, look in the mouth. In an injured
or suddenly ill victim, the airway can be blocked by mucous, blood, vomit or a
foreign object like a small toy or a piece of food.
·
If you see blood or
vomit in the mouth, wear gloves, and try to wipe the mouth clear with a tissue
or piece of cloth.
·
If a foreign object is
clearly seen in the mouth, remove it.
B
is Breathing
After
you open the airway, check for breathing. Sometimes opening the airway will
help the victim to start breathing again. Look, listen & feel for breath.
·
Look for the chest to
rise and fall.
·
Listen for breath with
your face close to victim’s nose and mouth.
·
Feel for air coming out
of the victim’s mouth and nose with your face close to victim’s nose and mouth.
Chest movement alone
does not mean that the victim is breathing.
Do not rely on any one sign.
Remember to keep the airway open.
If
victim is breathing, check the quality of the breathing. Does breathing seem normal for this victim or
is it rapid, shallow or labored? Is the victim gasping for air or wheezing
etc.? Abnormal breathing tells you that
something is wrong.
C
is Circulation
a) Pulse
You only need to check
the pulse if the victim is not breathing.
If the victim is breathing, then the heart must be beating. If the victim is not breathing, check the
pulse. There are two methods that you
can use to check. Which method you use
depends on the age of the victim.
·
If the victim is less
than one year old, check the pulse by placing 2 fingers (NOT the thumb) on the
inside of the infant’s arm between the elbow and the shoulder (brachial pulse).
·
If the victim is one
year old or older, check the pulse by placing two fingers on either side of the
neck, below the jaw (carotid pulse).
Feel for a pulse for
about 10 seconds. While checking the
pulse, remember to keep the airway open by keeping gentle pressure on the
victim’s forehead.
b) Bleeding
Is the victim bleeding
severely? Without moving the victim, check the victim’s body quickly for
blood. Look for blood soaked clothing or
pools of blood near the victim. Bleeding is severe if blood is spurting or
flowing freely from a wound or if you can’t stop it. We will cover how to
control bleeding later.
Importance of the ABC’s
1. Whenever
you have an unconscious victim or a victim with altered consciousness, check
the ABC’s first. DO NOT start any other first aid until you have checked them. By
checking them, you will be able to identify the conditions most in need of
immediate care.
2. It
is also important to keep checking the ABC’s because they can change.
B.
PRACTISE SESSION: PRIMARY SURVEY
1.
Check for consciousness
·
Tap and gently
shake person.
·
Shout, "Are
you OK?"
If person does not
respond,
·
Call for advanced
medical help
2.
Check for breathing
·
Look, listen, and
feel for about 10 seconds.
If not breathing or you
cannot tell,
·
Position casualty
onto back.
·
Roll person as a
single unit, while
supporting
the head and neck.
3.
Open the airway
·
If a c-spine injury
is not suspected, tilt head
back
and lift chin.
4.
Recheck breathing.
·
Look, listen, and
feel for about 10 seconds.
If person is not
breathing,
·
Keep head tilted back.
·
Pinch nose shut.
·
Seal your lips
tightly around person's mouth.
·
Give 2 slow
breaths, each lasting about 1 1/2 s.
·
Watch to see that
the breaths go in.
5.
Check for pulse
·
Locate Adam's
apple.
·
Slide fingers down
into groove of neck on side
closer
to you.
·
Feel for pulse for
10 seconds.
6.
Check for severe bleeding
·
Look from head to
toe for severe bleeding.
If person has a pulse
and is not breathing,
·
Do rescue
breathing.
If person does not have
a pulse,
7. Perform Chest Compression
Chest
compression technique consists of serial, rhythmic applications of pressure
over the lower half of the sternum (breastbone). To locate the correct hand
position for chest compression :
·
Maintain head tilt, run
your middle finger from the lower margin of the victim’s rib cage till you
reach the Xiphi Sternum.
·
Place your index finger
next to the middle finger.
·
Place the heel of one
hand next to the index finger.
·
Remove the index and
middle fingers.
·
Place the heel of the
other hand on top of the hand on the sternum.
·
Interlace the fingers
of both hands and lift the fingers off the chest wall.
·
Straighten both elbows
and lock then in position.
·
Position your shoulder
directly over the victim’s chest
·
Use your body weight to
compress the victim’s chest by at least 5cm.
·
Count your
compressions:
1,2,3,4,5,6,7,8,9-1
1,2,3,4,5,6,7,8,9-2
1,2,3,4,5,6,7,8,9-3
·
Perform chest
compressions at a rate of at least 100 per minute. Allow complete recoil of the
chest wall after each compression.
·
The ratio of
compression and ventilation is 30 compressions: 2 breaths.
·
Healthcare Providers –
Check pulse after 5 cycles of 30 compressions : 2 ventilations. If no pulse or
unsure presence of pulse, resume CPR.
·
Laypersons –
Continue performing CPR until help arrives or victim starts moving.
8.
Mouth-To-Mouth Breathing
To
perform mouth-to-mouth-breathing :
·
Maintain head tilt-chin
lift.
·
Pinch the nose with
your thumb and index finger to prevent air from escaping through the victim’s
nose.
·
Seal your mouth over the
victim’s mouth and give 2 short breaths in quick succession one after the
other.
·
Release the nostrils to
allow exhalation after each breath.
·
Each rescue breath
should make the chest rise.
·
The duration for each
breath is 1 second.
9.
Re-Assessment (For Healthcare Provides Only)
·
Assess the victim for
pulse and breathing after every 5 cycles of CPR 30:2.
·
If pulse is absent (if
unsure of pulse and victim has no breathing, assume cardiac arrest), continue
CPR 30:2.
·
If both the pulse and
breathing are present, position the victim in the recovery position.
·
Continue to monitor the
victim’s pulse and breathing every few minutes as these can stop suddenly.
ABC's of Life for Children (1 to Puberty):
Airway: Same as an Adult except look in
the airway for a potential choking object that potentially could be removed.
Breathing: Same as an Adult. If giving rescue
breaths, give a lower volume of air when giving breaths. Give just enough
breath to see the chest rise.
Circulation: Same as an Adult. Remember to Push
Hard and Push Fast. Do not hesitate or restrict compressions due to the smaller
size of the child. Recognize that performing poor compression equates to poor
circulation and cellular injury and death. Attempt to push 1/2 to 1/3 the chest
depth of the child. If the child is small in size, you may use one hand instead
of two when performing compressions. You may use the second hand to maintain an
open airway and stabilize the child during compressions.
ABC's of Life for Infants (Birth to Age 1):
Airway &
Breathing: Same as a
Child.
Circulation: Compressions have to performed
differently for infants than they would be for larger children and adults due
to their smaller size.
To perform compressions on an infant, place the infant
on a flat hard surface, face up, and locate the middle of the chest between the
breasts. Place two fingers of one hand on top of the sternum about a fingers
tips length below the nipple line. Place the second hand the infants head to
maintain an open airway and to stabilize the victim. Push on the chest using
the two fingers at the rate of 100 compressions per minute at a depth of 1/2 to
1/3 the chest depth. If giving CPR with rescue breathing perform 30
compressions to 2 breaths (30:2 ratio).
