FIRST-AID TREATMENTS

䠊
Give 2 rescue breaths (omittable)
a) If opening the airway does not cause the injured or ill person to
begin to breathe normally, give rescue breaths.
b) If there is a fear of infection because the injured or ill person has an
intraoral injury, you are hesitant about giving mouth-to-mouth
resuscitation, or getting and preparing the mouthpiece for rescue
breathing takes too long, omit rescue breathing and perform chest
compressions.
c) When performing rescue breathing, it is recommended to use a
mouthpiece for rescue breathing and other protective devices to
prevent infections.
d) While maintaining an open airway, pinch the person's nose shut with
your thumb and forefinger of the hand used to push down the
forehead.
e) Open your mouth widely to completely cover the mouth of the
injured or ill person so that no air will escape. Give rescue breathing
twice in about 1 second and check if the chest rises.

Cardiopulmonary resuscitation (CPR) (combination of chest compressions and
rescue breaths)
a) Chest compressions
1) Position of chest compressions
• Position the heel of one hand in the center of the chest, approximately between the nipples,
and place your other hand on top of the one that is in position.
2) Perform chest compressions
• Perform uninterrupted chest compressions of 30
at the rate of about 100 times per minute.
• While locking your elbows positioning yourself
vertically above your hands.
• With each compression, depress the chest wall
to a depth of approximately 4 to 5 cm.
b) Combination of 30 chest compressions and 2 rescue breaths
1) After performing 30 chest compressions, give 2 rescue
breaths. If rescue breathing is omitted, perform only chest
compressions.
2) Continuously perform the combination of 30 chest
compressions and 2 rescue breaths without interruption.
3) If there are two or more first-aiders, alternate with each other
approximately every two minutes (five cycles of
compressions and ventilations at a ratio of 30:2) without
interruption.
