CHOCKING-I




Foreign object lodged in the throat or windpipe, blocking the flow
of air. In adults piece o fFood. Young children -swallow small
objects.
Effects: cuts off oxygen to the brain
First Aid: Quick.
Sign:Hands clutched to the throat
Inability to talk
Difficulty breathing or noisy breathing
Inability to cough forcefully
Skin, lips and nails turning blue or dusky
Loss of consciousness
CHOCKING Contd:

Red Cross recommends a "five-andfive“ :
Give 5 back blows. First, deliver five back blows
between the person's shoulder blades with the heel of
your hand.


Give 5 abdominal thrusts. Perform five abdominal
thrusts (also known as the Heimlich maneuver).
Alternate between 5 blows and 5 thrusts until the
blockage is dislodged.
CHOCKING –For Unconscoius
Person

Lower the person on his or her back onto the floor.

Clear the airway. Be careful not to push the food or
object deeper into the airway, which can happen
easily in young children.

Begin cardiopulmonary resuscitation (CPR) object
remains lodged and the person doesn't respond after.
The chest compressions used in CPR may dislodge the
object. Remember to recheck the mouth periodically.
CHOCKING-Child Less Than One
Year

Assume a seated position and hold the infant
facedown on your forearm, which is resting on your thigh.

Thump the infant gently but firmly five times on the middle of
the back using the heel of your hand. The combination of gravity and the
back blows should release the blocking object.

Hold the infant faceup on your forearm with the head lower
than the trunk if the above doesn't work. Using two fingers placed at the
center of the infant's breastbone, give five quick chest compressions.

Repeat the back blows and chest thrusts if breathing
doesn't resume. Call for emergency medical help.

Begin infant CPR if one of these techniques opens the airway but
the infant doesn't resume breathing.
FAINTINGFainting -Blood supply to the brain is
momentarily inadequate, causing you to
lose consciousness(Brief),
 No medical significance.
 But Investigate to rule out Any
 An emergency.

FAINTING-Contd

Lie down or sit down.
Place your head between your knees
If someone else faints

Position the person on his or her back. person is


breathing, raising the person's legs above heart level — about 12
inches (30 centimeters) Loosen belts, collars or other constrictive
clothing


Check the person's airway to be sure it's clear. Watch for
vomiting.
Check for signs of circulation (breathing, coughing
or movement).
If absent, begin CPR.

Cardiopulmonary resuscitation
(CPR)



Cardiopulmonary resuscitation (CPR) is
a lifesaving technique useful in many
emergencies,
Situations:Heart attack or Near drowning,
Done When: someone's breathing or heartbeat has stopped.
AHA- recommends that everyone — untrained bystanders and
medical personnel alike — begin CPR with chest compressions.

Better to do something than nothing Remember, the
difference between your doing something and doing nothing
could be someone's life.
Cardiopulmonary resuscitation
If an AED is immediately available, deliver
one shock if instructed by the device, then
begin CPR.
 Remember to spell C-A-B
 The AHA uses the acronym of CAB —
compressions, airway, breathing — to

help people remember the order to perform the steps of CPR.
Cardiopulmonary resuscitation
CPR
Before starting CPR, check:

Is the person conscious or unconscious?

If the person appears unconscious, tap or shake his
or her shoulder and ask loudly, "Are you OK?"
NO response and two people are available, one call
the local emergency number and one should begin
CPR.
Alone and have access to phone, call before


beginning CPR — unless you think the person has become
unresponsive because of suffocation (such as from drowning). In
this special case, begin CPR for one minute and then call local
emergency number.
Cardiopulmonary resuscitation
(CPR)

Advice By AHA:
Untrained. Provide hands-only CPR. i.e uninterrupted chest
compressions of about 100 a minute until paramedics arrive
(described in more detail below). You don't need to try rescue
breathing.

Trained and ready to go. 30 chest compressions before
checking the airway and giving rescue breaths.

Trained but rusty. If you've previously received CPR training
but you're not confident in your abilities, then just do chest
compressions at a rate of about 100 a minute. (Details described
below.)
IMPORTANCE OF LEARNING CPR
Advice applies to adults, children and
infants needing CPR, but not newborns.
 CPR can keep oxygenated blood flowing to the brain and other

vital organs until more definitive medical treatment can restore a
normal heart rhythm.

When the heart stops, the lack of
oxygenated blood can cause brain
damage in only a few minutes. A person
may die within eight to 10 minutes.
CPR-HOW TO LEARN
Take an accredited first-aid training
course, CPR and to use an automated
external defibrillator (AED).
 Before you begin
 Remember to spell C-A-B
 The American Heart Association uses the
acronym of CAB — compressions,
airway, breathing — to help people
remember the order to perform the steps
of CPR.

Cardiopulmonary resuscitation
(CPR) Contd-I

Compressions: Restore blood circulation

Put the person on a firm surface.



Kneel next to the person's neck and shoulders.
Place the heel of one hand over the center of the person's
chest, between the nipples.
Use your upper body weight the chest at least 2 inches
(approximately 5 centimeters). Push hard at a rate of about 100
.
compressions a minute

If you haven't been trained in CPR, continue chest compressions
until signs of movement or until emergency medical personnel take
over& Go on to checking the airway and rescue breathing.
Cardiopulmonary resuscitation
(CPR) Contd-I

Airway: Clear the airway

A-trained in CPR perform 30 chest compressions,
open the person's airway using the head-tilt, chin-lift
maneuver. Put your palm on the person's forehead
and gently tilt the head back. Then with the other
hand, gently lift the chin forward to open the airway.
Check breathing in five or 10 seconds. Look for chest
motion, listen for normal breath sounds, and feel for the
person's breath on your cheek and ear. Gasping is not

considered to be normal breathing.
Cardiopulmonary resuscitation
(CPR) Contd-II

Trained: No Normal breathing normally and you are
trained in CPR, begin mouth-to-mouth breathing.

Untrained: person is unconscious from a heart attack,
skip mouth-to-mouth breathing and continue chest
compressions.
Breathing: Breathe for the person
Rescue breathing can be mouth-to-mouth breathing or
mouth-to-nose breathing if the mouth is seriously injured
or can't be opened.


Cardiopulmonary resuscitation
(CPR) Contd-III



With the airway open (using the head-tilt, chin-lift
maneuver), pinch the nostrils shut for mouth-to-mouth
breathing and cover the person's mouth with yours,
making a seal.
30:2 considered one cycle.
Resume chest compressions to restore circulation.
Cardiopulmonary resuscitation
(CPR) Contd-Iv

If the person has not begun moving after five cycles
(about two minutes) and an automated external
defibrillator (AED) is available, apply it and follow the
prompts. Administer one shock, then resume CPR —
starting with chest compressions — for two more
minutes before administering a second shock.


Untrained In AED:Other emergency medical operator
may be able to guide you in its use. If an AED isn't
available, go to step 5 below.
Continue CPR until there are signs of movement or
emergency medical personnel take over.
Cardiopulmonary resuscitation
(CPR) Contd-V


To perform CPR on a child
The procedure for giving CPR to a child age 1 through 8
is essentially the same as that for an adult.
Differences are as follows:

If you're alone, perform five cycles of compressions and
breaths on the child — this should take about two
minutes — before calling your local emergency number
or using an AED.

Use only one hand to perform chest compressions.

Breathe more gently.
Cardiopulmonary resuscitation
(CPR) Contd-VI



Use the same compression-breath rate as is used for
adults:One Cycle-30:2
Five cycles (about two minutes) of CPR, if there is no
response and an AED is available, apply it and follow the
prompts. Use pediatric pads if available, for children
ages 1 through 8. If pediatric pads aren't available, use
adult pads. Do not use an AED for children younger
than age 1. Administer one shock, then resume CPR —
starting with chest compressions — for two more
minutes before administering a second shock.
Continue until the child moves or help arrives
Cardiopulmonary resuscitation
(CPR) Contd-VII



To perform CPR on a baby
Cardiac arrests in babies occur from lack of oxygen,
such as from drowning or choking. If you know the baby
has an airway obstruction, perform first aid for choking. If
you don't know why the baby isn't breathing, perform
CPR.
To begin, examine the situation. Stroke the baby and
watch for a response, such as movement, but don't
shake the baby.
Cardiopulmonary resuscitation
(CPR) Contd-VIII



If there's no response, follow the CAB procedures below
and time the call for help as follows:
If you're the only rescuer and CPR is needed, do CPR
for two minutes — about five cycles — before calling
your local emergency number.
If another person is available, have that person call
for help immediately while you attend to the baby.
Cardiopulmonary resuscitation
(CPR) Contd-IX





Compressions: Restore blood circulation
Place the baby on his or her back on a firm, flat surface,
such as a table. The floor or ground also will do.
Imagine a horizontal line drawn between the baby's
nipples. Place two fingers of one hand just below this
line, in the center of the chest.
Gently compress the chest about 1.5 inches (about 4
centimeters).
Count aloud as you pump in a fairly rapid rhythm. You
should pump at a rate of 100 compressions a minute.
Cardiopulmonary resuscitation
(CPR) Contd-X



Airway: Clear the airway
After 30 compressions, gently tip the head back by lifting
the chin with one hand and pushing down on the
forehead with the other hand.
In no more than 10 seconds, put your ear near the
baby's mouth and check for breathing: Look for chest
motion, listen for breath sounds, and feel for breath on
your cheek and ear.
Cardiopulmonary resuscitation
(CPR) Contd-X



Breathing: Breathe for the baby
Cover the baby's mouth and nose with your mouth.
Prepare to give two rescue breaths. Use the strength of
your cheeks to deliver gentle puffs of air (instead of deep
breaths from your lungs) to slowly breathe into the
baby's mouth one time, taking one second for the breath.
Watch to see if the baby's chest rises. If it does, give a
second rescue breath. If the chest does not rise, repeat
the head-tilt, chin-lift maneuver and then give the second
breath.
Cardiopulmonary resuscitation
(CPR) Contd-XI




If the baby's chest still doesn't rise, examine the mouth
to make sure no foreign material is inside. If an object is
seen, sweep it out with your finger. If the airway seems
blocked, perform first aid for a choking baby.
Give30:2.
Perform CPR for about two minutes before calling for
help unless someone else can make the call while you
attend to the baby.
Continue CPR until you see signs of life or until
medical personnel arrive.
Respiratory Emergency – Pulmonary Embolus
