Which method of measuring blood pressure yields the systolic value?

• A. Auscultation With Stethoscope
• B. Palpation Method
• C. Automated Cuff With Oscillations
• D. Doppler Ultrasound

Answer: (B)

Detecting the moment the pulse returns as you deflate the cuff gives the systolic pressure. In the palpation method, you inflate until the arterial pulse disappears, then slowly deflate; the pressure at which the pulse reappears is the systolic value—the threshold where blood begins to flow enough to create a palpable pulse. Since you’re only noting when a pulse is felt, this method does not provide a diastolic reading.

Other methods can yield both numbers: auscultation with a stethoscope uses Korotkoff sounds to determine systolic and diastolic, automated cuff devices estimate both from cuff oscillations, and Doppler can indicate systolic pressure by detecting flow. Thus, palpation uniquely gives the systolic value alone in this context.
