AHA BLS Study Guide Questions AndAnswers
Chain of Survival: Adult - correct answer Emergency
Cardiovascular Care
1 - Immediate recognition of cardiac arrest and activation
of the emergency response system
2 - Early cardiopulmonary resuscitation (CPR) with an
emphasis on chest compressions
3 - Rapid defibrillation
4 - Effective advanced life support
5 - Integrated post-cardiac arrest care
High-quality CPR - correct answer Start compressions
within 10 seconds of recognition of cardiac arrest.
Push hard, push fast: rate of 100/min with a depth of at
least 2 in (5cm) for adults, approximately 2 in (5cm) for
children, and approximately 1.5 in (4cm) for infants.
Allow complete chest recoil for each compression.
Minimize interruptions in compressions (limit to less than
10s).
Give effective breaths that make the chest rise.
Avoid excessive ventilation.

2010 AHA Key Changes (sequence) - correct answer
Changes in BLS sequence from ABC (airway, breathing,
chest compressions) to CAB (chest compressions, airway,
breathing) for adults, children, and infants.
This is because chest compressions were often delayed
while rescuer opened airway, deliver mouth-to-mouth,
retrieve barrier device, or gathered and assembled
ventilation equipment.
CAB makes delivery of compressions sooner and the
delay in giving breaths sooner - deliver first cycle of 30
compressions (approximately 18 seconds or less); for 2-
rescuer infant or child CPR the delay will be even shorter.
2010 AHA key Changes (Emphasis on High-Quality CPR) -
correct answer Compression rate of at least 100/min
(rather than "approximately")
Depth of at least 2 in (5cm) for adults and children, 1.5 in
(5cm) for infants. No longer 1.5 - 2 in for adults and

absolute depth for children and infants is deeper than in
previous guidelines.
Allowing complete chest recoil, minimizing interruptions
in compressions, and avoiding excessive ventilation
continue to be important in high-quality CPR.
Increased focus on a team approach to CPR.
Example: one rescuer activates EMS, second begins
compressions, third is either providing ventilation or
getting equip for it, fourth is getting the defibrillator and
preparing to use it.
2010 AHA Key Changes (No Look, Listen, Feel) - correct
answer Step removed because bystanders often failed to
start CPR when they observed agonal gasping. Activate
EMS and check for response and breathing
simultaneously. If adult is unresponsive and not breathing
normally (only gasping) and has no pulse, begin CPR. For
infant and child, CPR is performed if the victim is
unresponsive and not breathing only gasping and has no
pulse.
For all victims (except newborns) CPR begins with
compressions and then opening airway and giving 2
breaths per cycle.
