BLS AHA FOR HEALTHCARE
PROVIDERS
General Principles
What allows the heart to refill with blood and is necessary for chest compressions to
create blood flow?
● Chest recoil
What are the 4 steps of BLS?
● Assess: Palpate carotid
● Activate: EMS, get AED
● Check pulse
● 10 second rule: C-A-B sequence
What are the 6 steps of critical concepts?
● Start compressions within 10 seconds of recognition of cardiac arrest
● Push hard and fast: compress at rate of 100/min
● Depth of at least 2" (5cm) for child/adult, 1 1/2" (4cm) for infants
● Allow complete chest recoil
● Limit compression interruptions to less than 10 seconds
What is the time frame to start CPR once suspect of cardiac arrest?
● 10 seconds
What is the C-A-B-D sequence?
● Chest compressions
● Airway
● Breathing
● Defibrillation
Compression Techniques
What is the proper chest compression technique?
● Put heel of one hand on the center of the victim's chest on the lower half of
the breastbone
, What is the compression rate?
● Deliver compressions at a rate of 100/min
What is the depth of compression for adults and children?
● 2 inches
What is the depth of compression for infants?
● 1/3 of anterior/posterior diameter of chest, 1 1/2" or 4cm
What does chest recoil allow for?
● Blood to flow into the heart and is necessary for chest compressions to create
blood flow. These compressions and recoils should be equal
When compressions are of the appropriate depth, what does it create?
● Blood flow to the body
Compression-to-Breath Ratios
What is the compression to breath ratio for lone rescuer child CPR?
● 30 compressions to 2 breaths
What is the compression-to-breaths ratio for 2-rescuer child CPR?
● 15 compressions to 2 breaths
What is the infant/child compression ratio?
● One rescuer: 30:2
● Two rescuer: 15:2
What is the lone rescuer compression-ventilation ratio?
● 30 compressions to 2 ventilations
Rescue Breathing
How often do adults require rescue breathing?
● 1 breath every 5 to 6 seconds
How often do infants and children require rescue breathing?
