SHOCK AND ITS SYMPTOMS
● insucient return of blood ow to the heart, resulting in
an inadequate supply of oxygen to all organs and tissues
of the body.
● Pale, cold, clammy skin
● Rapid, weak pulse
● Increased, shallow breathing rate
● Expressionless face and staring eyes
49
● Firmly applying direct pressure to the wound until
bleeding stops or emergency rescuers arrive.
● Pressure should be applied using cloth or gauze with
additional material added if bleeding continues.
EXTERNAL HEMORRHAGE
50
FIRST AID FOR SHOCK
● Maintain an open airway for the victim.
● Call for assistance.
● Keep the patient lying down with the head lower than the
rest of the body.
● Attempt to control bleeding or other cause of shock if
known.
● Keep the victim warm until help arrives.
51
CARDIOPULMONARY RESUSCITATION
● emergency lifesaving procedure performed when the
heart stops beating
● aims to keep blood and oxygen owing through the body
when a person’s heart and breathing have stopped
● can keep oxygenated blood owing to the brain and
other vital organs until more denitive medical
treatment can restore a normal heart rhythm
52
HOW TO PERFORM CPR
● Kneel beside the patient and place your hands in the
middle of the patient’s chest.
● Cover the rst hand with the heel of the on the other
hand, interlocking the ngers. The ngers should be
raised so they do not touch the ribcage.
● Lean forward (shoulders directly over the patient’s chest)
and press down on the chest for about two inches.
Release the pressure to allow the chest to come back up.
Do not release your hands. Repeat. Give 30
compressions at a rate of 100 compressions per minute.
● Tilt the patient’s head and lift the chin to open the airway
allowing the mouth to fall open slightly.
● Deliver rescue breaths. Pinch the nose shut and place
your mouth over the person's mouth to make a complete
seal. Blow into the person's mouth to make the chest
rise. Deliver two rescue breaths, then continue
compressions
53
BEFORE GIVING CPR
● Check the scene and the person.
● Patient lying on his/her back on a steady surface
● Call 911 for assistance
● Ask a bystander to call 911, or a there is no call 911 and
begin administering assistance
● Check for breathing. If there is no breathing begin CPR
54
55
56
56
57
RED CROSS CPR STEPS
● Continue cpr steps
● Replicate the cycle of 30 chest compressions, to be
followed by two rescue breaths Repeat this cycle until
person exhibits signs of life, such as breathing, an AED
becomes available, or a trained medical responder
arrives on scene
58
FOR THE GENERAL PUBLIC OR BYSTANDERS WHO WITNESS
AN ADULT COLLAPSE:
● compression-only CPR, or Hands-Only CPR.
● without mouth-to-mouth breaths
● Call 9-1-1 (or send someone to do that)
● Push hard and fast in the center of the chest
59
FOR HEALTHCARE PROVIDERS AND THOSE TRAINED
● conventional CPR using chest compressions and
mouth-to-mouth breathing at a ratio of 30:2
compressions-to-breaths.
● In adult victims of cardiac arrest, it is reasonable for
rescuers to perform chest compressions at a rate of 100
to 120/min and to a depth of at least 2 inches (5 cm) for
an average adult
60
