Terms in this set (...)

AED
Automatic External Defibrillator
AP
anterioposterior
CPR
cardiopulmonary resuscitation
HCP
healthcare provider
*Newly born
Excluding the newly born, in who the etiology of an arrest is nearly always asphyxia
Recognition in anyone
Unresponsive (for all ages)
Recognition in adults
No breathing or no normal breathing (ie. only gasping)
Recognition in children or infants
No breathing or only gasping
Recognition in anyone
No pulse palpated within 10 seconds for all ages (Healthcare Provider only)
CPR sequence
C-A-B
Compression rate
At least 100/min up to 120/min
Compression depth in adults
At least 2 inches (5 cm) but not more than 2.4 inches (6 cm)
Compression depth in children
At least 1/3 AP diameter
About 2 inches (5 cm)
Compression depth in infants
At least 1/3 AP diameter
About 2 inches (5 cm)
Chest wall recoil
Allow full recoil of chest after each compression; do not lean on the chest after each compression
Compression interruptions
Minimize interruptions in chest compressions
Attempt to limit interruptions to <10 seconds
Airway
Head tilt-chin lift (HCP suspected trauma: jaw thrust)
Compression-to-ventilation ratio in adults
30:2
1 or 2 rescuers
Compression-to-ventilation ratio in children
30:2
Single rescuer

15:2
2 HCP rescuers
Compression-to-ventilation ratio in infants
30:2
Single rescuer

15:2
2 HCP rescuers (thumbs-encircling hands technique)
Ventilations when rescuer is untrained or not proficient
Compressions only
Ventilations with advanced airway (HCP)
1 breath every 6-8 seconds (8-10 breaths/min)

Asynchronous with chest compressions
About 1 second per breath
Visible chest rise
Defibrillation
Attach and use AED as soon as available. Minimize interruption in chest compessions before and after each shock; resume CPR beginning with compressions immediately after each shock if needed.
