BLS (Basic life support) Exam
What are the five links in the out of hospital cardiac arrest (OHCA) chain? - answer1)
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 - answerOccurs when the heart develops an abnormal rhythm
and cant pump blood.
Heart attack - answerOccurs when blood flow to part of the heart muscle is blocked.
In which locations do most out-of-hospital cardiac arrest occur? - answerHomes

answerStart high-quality CPR, beginning with chest compressions

What are the rate and depth for chest compressions on an adult? - answerA rate of 100
to 120 compressions per minute and a depth of at least 2 inches
