Where should you check for a pulse in an unresponsive adult?
Answer: Carotid pulse in the neck
For adults, the carotid pulse in the neck is the recommended site because it is the most accessible and reliable during an emergency.
When two rescuers are performing CPR on an adult, what is the compression-to-ventilation ratio?
Answer: 30:2
Two rescuers performing adult CPR still use a 30:2 ratio; a 15:2 ratio is reserved for two-rescuer infant and child CPR.
How often should rescuers switch roles during adult CPR to avoid fatigue?
Answer: Every 2 minutes (about 5 cycles)
AHA recommends switching the compressor role every 2 minutes (approximately every 5 cycles of 30:2) to maintain high-quality compressions.
What is the maximum allowable interruption time for chest compressions?
Answer: Less than 10 seconds
Compressions should not be interrupted for more than 10 seconds at a time to maintain coronary and cerebral perfusion pressure.
What is the correct hand position for adult chest compressions?
Answer: Heel of one hand on the lower sternum with the other hand on top, fingers interlaced
Use the heel of one hand on the lower sternum, place the other hand on top, and interlace fingers to keep them off the ribs while compressing.
What is 'cardiac arrest' as it relates to CPR?
Answer: Sudden cessation of the heart's pumping function
Cardiac arrest is the sudden, unexpected loss of heart function resulting in no pulse, no breathing, and unconsciousness — the primary indication for CPR.
