CPR Course - Adult/Child/Infant CPR Review (14 of 14)  
  Lets summarize key concepts, which were introduced during the course and are important to know for the exam:

Timeline for brain death/permanent damage after the heart has stopped beating:

0 to 4 minutes after exhibiting symptoms

Chances of Brain Damage Minimal

4 to 6 minutes after exhibiting symptoms

Chances of Brain Damage Possible

6 to 10 minutes after exhibiting symptoms

Chances of Brain Damage Likely

Greater than 10 minutes after exhibiting symptoms

Chances of Brain Death Likely

The following condition warrants immediate CPR: 1) Victim is unconscious; 2) Victim is not breathing; 3) Victim has no pulse

Before CPR
Victims and you are safe, if adult call 911 before CPR, if child/infant initiate CPR and perform 5 reps, 30 compressions each, with 2 rescue breaths or 2 minutes of CPR, then call 911, also make certain you know where you are to help notify emergency services.


  • C-Compressions, after checking for pulse via carotid artery or brachial artery for infant, perform 30 compressions, interrupted by two mouth to mouth breaths, one second each; repeat until emergency services arrive 
  • A-Airway, determine if the person is breathing and check for obstructions by opening airway;
  • B-Breathing, perform two mouth to mouth breaths 1 second each;
  • Recommended position for performing CPR is to have victim lying flat on his back
  • Recommended rate for effective compressions for adult/child is 100 to 120 compressions per minute
  • When performing compressions, make sure the chest returns to its original position
  • When performing adult/child CPR the depth of the compressions should be at least 2 inches deep (but not greater than 2.4 inches)
  • When performing infant CPR make sure your compressions are 1/3 to 1/2 the depth of the chest
  • For child, depending on the size you can use one or two hands
  • For infant, use two fingers
  • If not comfortable performing mouth to mouth, call 911, but at least administer external chest compressions until help arrives
