An EMT is performing CPR on an adult patient. The patient is pulseless and apneic. What is the recommended compression depth for an adult patient?
- AAt least 1 inch (2.5 cm)
- BAt least 2.4 inches (6 cm)
- CAt least 1.5 inches (3.8 cm)
- DAt least 2 inches (5 cm)
Show answer & explanationAnswer & explanation
Correct answer: D. At least 2 inches (5 cm)
For adult CPR, the American Heart Association (AHA) guidelines recommend a compression depth of at least 2 inches (5 cm) but no more than 2.4 inches (6 cm).
Why the other options are wrong
- A. This depth is insufficient for effective adult chest compressions.
- B. While 2.4 inches (6 cm) is within the acceptable range, 'at least 2 inches' is the minimum specified by guidelines, and 'at least 2.4 inches' could lead to over-compression for some rescuers.
- C. This depth is insufficient for effective adult chest compressions.
Adult CPR Compression Depth
The recommended depth for chest compressions during adult CPR is at least 2 inches (5 cm) and no more than 2.4 inches (6 cm).
- Essential for adequate blood flow to vital organs.
- Too shallow, and blood flow is insufficient.
- Too deep, and injuries can occur.
Memory trick: For adults, think 'Two to the chest, but no more than two point four, to keep them alive and wanting more!'
