An EMT is performing CPR on an adult patient in cardiac arrest. What is the recommended compression depth for an adult?
- AAt least 2.5 inches (6.4 cm)
- BAt least 1.5 inches (3.8 cm)
- CApproximately 1 inch (2.5 cm)
- DAt least 2 inches (5 cm) but no more than 2.4 inches (6 cm)
Show answer & explanationAnswer & explanation
Correct answer: D. At least 2 inches (5 cm) but no more than 2.4 inches (6 cm)
For effective adult CPR, chest compressions should be performed to a depth of at least 2 inches (5 cm) but no more than 2.4 inches (6 cm) to ensure adequate blood flow while avoiding injury.
Why the other options are wrong
- A. 2.5 inches is slightly too deep and exceeds the recommended maximum depth, potentially increasing risk of injury.
- B. 1.5 inches is too shallow for effective adult chest compressions.
- C. 1 inch is too shallow for effective adult chest compressions.
Adult CPR Compression Depth
The recommended depth for chest compressions during adult cardiopulmonary resuscitation (CPR) is crucial for generating adequate blood flow to vital organs.
- At least 2 inches (5 cm) deep.
- No more than 2.4 inches (6 cm) deep.
- Ensures effective circulation.
- Avoids excessive depth and potential injury.
