The assistant cannot hear any Korotkoff sounds on the first attempt and wants to try again on the same arm. What should be done?
- A.Reinflate immediately to a much higher pressure
- B.Wait one to two minutes before reinflating the cuff on that arm
- C.Switch to squeezing the arm with both hands
- D.Chart the systolic as zero and move on quickly
Correct answer
B. Wait one to two minutes before reinflating the cuff on that arm
Why
The cuff should be fully deflated and the arm rested for one to two minutes before another attempt on the same arm. Immediate reinflation traps blood in the arm and distorts the next reading.
