For carotid pulse absent duration, what is required?

• A. 60 seconds
• B. 30 seconds
• C. 15 seconds
• D. 5 seconds

Answer: (B)

Determining when to declare no pulse hinges on how long you observe for the carotid pulse to be absent. In this item, the required duration is 30 seconds. The idea is to perform a thorough check long enough to be confident that a usable pulse isn’t present, including the possibility of a weak or irregular pulse that could be missed in a shorter check. If no pulse is felt after this full 30-second assessment, you would proceed with chest compressions. Shorter checks (like 5 or 15 seconds) risk missing a faint or irregular pulse, while a much longer check (such as 60 seconds) would unnecessarily delay starting CPR. So 30 seconds is chosen to balance accuracy with timely treatment.
