The BLS Course focuses on preparing students to perform ___ skills. [
Ans: ] CPR
What are the two components of CPR? [ Ans: ] 1) chest compressions
2) breaths

*Start compressions within 10 seconds
*Push hard, push fast
*Allow complete chest recoil
*Minimize interruptions
*Give effective breaths
*Avoid excessive ventilation [ Ans: ] High-Quality CPR

compressions. Try to limit interruptions to less than __ seconds. [ Ans: ]
10
What constitutes an effective breath in high-quality CPR? [ Ans: ] Making
