BLS Algorithm in Adults

BLS for Adults – Step 1

Assess the scene and the victim:

• —Make sure you and victim are safe! 
• —Try to rouse the victim by shaking and shouting

• —Is he breathing?  Gasping is NOT effective breathing
• —If breathing, call for help and continue monitoring 

BLS for Adults – Step 2

• —Use cell phone if available
• —If alone, you may leave the victim to activate the emergency response system before CPR
• —If others are near, send them to activate emergency response system and get an AED while you start chest compressions

BLS for Adults – Step 3

Check pulse:

• —Locate the carotid pulse on the side of the neck beside the trachea (windpipe)
• —If you cannot DEFINITELY feel a pulse within 10 seconds, begin chest compressions
• —Check for no more than 10 seconds

BLS for Adults – Step 4

Start High Quality CPR:

• Compression Rate 100-120/minute
• Compression Depth:

1. Between 2 and 2.4 inches (5-6 cm)

• Allow complete chest recoil between compressions
• Do not lean on chest between compressions
• Minimize interruptions to chest compressions

BLS for Adults – Step 5

• —When AED arrives, use it!
• —The AED is a battery-operated device that provides instructions for use. Follow its instructions.
• —AED will only allow the rescuer to administer a SHOCK if it detects a shockable rhythm
