Measures and Records Manual Blood Pressure

Take a blood pressure with a cuff and stethoscope. Both recorded numbers must be within 8 mm Hg of the evaluator. State specific: check whether your state tests this or electronic BP.

5-10 minutes•12 steps•1 critical

Why this matters

Clean the stethoscope, deflate slowly, land within 8.

Quick tips

  • Wipe the earpieces and bell or diaphragm with alcohol first.
  • Inflate to 160-180 mm Hg; if you hear a beat at once, release all the air and reinflate (never above 200).
  • First sound is systolic, last sound is diastolic. Deflate slowly.

Common mistakes

  • Deflating too fast and missing the first or last sound.
  • Skipping the alcohol wipe.
  • Starting too low and guessing instead of reinflating.
  • Rounding down or to an odd number.
