BLS (Basic life support)
What are the five links in the out of hospital cardiac arrest (OHCA) chain? - ANS-1) Immediate
recognition of cardiac arrest and activation of the emergency response system
2) Early CPR with and emphasis on chest compressions
3) Rapid defibrillation with and AED
4) Effective advance life support (including rapid stabilization and transport to post-cardiac
arrest care)
5) Multidisciplinary post-cardiac arrest care
Sudden cardiac arrest - ANS-Occurs when the heart develops an abnormal rhythm and cant
pump blood.
Heart attack - ANS-Occurs when blood flow to part of the heart muscle is blocked.
In which locations do most out-of-hospital cardiac arrest occur? - ANS-Homes
What is the most common cause of cardiac arrest in children? - ANS-Respiratory failure or
shock
What is the first action you should take when you witness someone collapse and are the first
rescuer at the scene? - ANS-Verify that the scene is safe for you and the victim
If the victim doesn't respond when you touch their shoulders and shout, "Are you OK?" What
should you do next? - ANS-Shout for nearby help
As you check the victim for a pulse and breathing, you notice them gasping for air and making
"snorting" sounds. You do not feel a pulse. What should you do next? - ANS-Start high-quality
CPR, beginning with chest compressions
What is the ratio of chest compressions to breaths when providing CPR to an adult? - ANS-30
compressions to 2 breaths
What are the rate and depth for chest compressions on an adult? - ANS-A rate of 100 to 120
compressions per minute and a depth of at least 2 inches
What actions should you take when more rescuers arrive? - ANS-Assign tasks to other rescuers
and rotate compressors every 2 minutes or more frequently if needed to avoid fatigue
