2. Time is critical
• > 300,000 people experience sudden cardiac
death in prehospital settings each year.
• If resuscitation begins within a few
minutes, many of these individuals have a
chance for survival.

3. Time is Critical!
• To begin resuscitation within a few minutes:
• Patient’s collapse witnessed
• EMS immediately activated
• CPR started immediately
• Defibrillation within minutes

4. Review of the Circulatory System
What is the function of the
circulatory system?
4
10. Heart Physiology
• LV contracts – sends wave of blood
• Pressure wave felt as pulse
• No contraction = No blood flow = cardiac
arrest
10
11. Time is Critical!
• Brain damage begins
in 4–6 min
• Brain damage
irreversible in 8–10
min
Circulation must be
restored within 4–
6 minutes.
11
12. CPR
• Provides minimal amount of
circulation/oxygenation until cause of cardiac
arrest corrected
• External chest compressions circulate blood
• Artificial ventilations provide O2 to lungs

16. AMERICAN HEART ASSOCIATION:
2010 GUIDELINES
Health Care Provider*
 “PUSH HARD AND PUSH FAST”
 At least 100 COMPRESSIONS / MINUTE*
 Allow the chest to recoil -- equal compression and relaxation times
 <10 seconds for pulse checks or rescue breaths
 Compression Depth*
 Adults 2”
 Child/Infant 1/3 depth of chest 1.5" infant 2" child
 Avoid excessive ventilations
16
17.  A-B-C changed to C-A-B*
 Critical element is chest compressions
 Delay in A-B
 Avoidance of A & B
 Early defib
 If alone--call and retrieve AED
 Exception asphyxial arrest
AMERICAN HEART ASSOCIATION:
2010 GUIDELINES
17
19. • Cricoid pressure not recommended
• Advanced airway = 1 every 6-8 seconds
• Adult: 1 every 5-6 Peds: 1 every 3
• With advanced airway- no pause
AMERICAN HEART ASSOCIATION:
2010 GUIDELINES
19
29. CPR - Children
• Use heel of one
hand
• Keep airway open
with other hand
• 30 compressions:2
ventilations if alone
(2 rescuers use 15:2)
30. CPR - Infant
• Give chest thrusts and
puffs of air
• 30 compressions:2
ventilations if alone
• 15 compressions: 2
ventilations with 2
rescuers
52. Summary
• Continual beating, or contracting, of the heart
is necessary to keep blood circulating
throughout the body.
• Brain damage begins in 4 to 6 minutes of
cardiac arrest.
• There are many causes of sudden cardiac
death, but the most common is ventricular
fibrillation.
52
53. Summary
• Survival from cardiac arrest depends on the
sequence (chain) of survival.
• Rescuers are critically important in
maintaining the sequence (chain) of survival.
