2. CARDIOVASCULAR RESUSCITATION
STAGES
C - circulation - the pressure on the
chest to maintain blood circulation
A – airway opening
B- breathing

3. ASSESSMENT OF AIRWAY AND
BREATHING IS THE CRUCIAL STEP
 Observe the patient and determine if the apnea
is present
 Observe chest expansion
 Absent of chest movement suggests apnea

4. AIRWAY OBSTRUCTION
The patient`s tongue is
the most common
cause of airway
obstruction

5. OPENING THE AIRWAY
1. Hand tilt-chin lift- if Head or neck injury is
not suspected
2. Jaw trust maneuver – if head or neck injury is
suspected
If a head or neck injury is suspected, use the jaw-thrust
maneuver to reduce neck and spine movement. Switch to
head head tilt chin lift maneuver if the jaw thrust does not
open the airway
If multiple rescuers are available, one rescuer can perform a
jaw thrust while another rescuer provides breaths with a

AND EXHALED AIR

11. BARRIER DEVICES

12. POCKET MASK
- Pocket masks usually have a 1-way
valve, which diverts exhaled air, blood or
bodily fluids away from the rescuer
- The valve allows the rescuer`s breath to
enter the victim`s mouth and nose and
diverts the victim`s exhaled air away from
the rescuer
- Pocket masks are available in different
sizes for adults, children and infants

14. -Is used to provide the positive-pressure ventilation to a
victim who is not brathing or not breathing normally
- If not attached to oxygen flow it provides about 21%
oxygen from the room air
- During CPR 2 rescuers are recommended to deliver
effective ventilation.

17. ADULT BREATHS
Remember the following when interrupting chest
compressions to give 2 breaths with a barrier device:
 Deliver each breath over 1 second
 Note visible chest rise with each breath
 Resume chest compressions in less than 10 seconds

18. Rescuer 1 (compressions)
Location is at the victims side
•Make sure the victim is face up on a firm, flat surface
•Perform chest compressions : rate of 100 to 120 /min, compress at least 5cm
(2inches ) for adults
•Allow the chest to recoil completely after each compression
•Minimize interruptions in compressions
•Compression ventilation ratio 30:2
•Count compressions out loud
•Switch compressions about every 5 cycles or every 2 min . Take less than 5
seconds to switch

19. Rescuer 2 (breaths)
Location is at the victims head
• Maintain an open airway by using either head tilt-chin lift or jaw thrust.
• Give breaths , watching for chest rise and avoiding excessive ventilation
• Encourage the first rescuer to perform compressions that are deep
enough and fast to allow complete recoil between compressions
• When only 2 rescuers are available, switch compressions about every 5
cycles or every 2 min taking less than 5 sec to switch
