Proper Seated BP Measurement in the Office

  • Step 1: Properly prepare the patient
    • The patient should relax and sit in a chair with feet flat on the floor and back supported. They should be seated for 3-5 minutes without talking or moving before recording the first BP measurement
    • The patient should avoid caffeine, exercise, and smoking for ≥ 30 minutes before measurement
    • The patient should empty their bladder before measurement.
    • Neither the patient or clinician should talk during the rest period or during measurement
    • Remove clothing covering the location of cuff placement.
  • Step 2: Use proper techniques
    • Use a validated, calibrated upper-arm cuff BP measurement device.
    • Support the patient’s arm
    • Position the middle of the cuff on the patient’s upper arm at the level of the right atrium
    • Use the correct cuff size so that the bladder encircles 75%-100% of the arm
    • Use the stethoscope diaphragm or bell for auscultatory readings
  • Step 3: Take the proper measurements needed for diagnosis and treatment of elevated BP/hypertension
    • On the first visit, record BP in both arms. Then use the arm that gives the higher initial reading for subsequent readings
    • Wait 1-2 minutes between repeated measurements
    • For auscultatory determinations, use a palpated estimate of radial pulse obliteration pressure to estimate SBP. Inflate the cuff 20-30 mm Hg above that level for an auscultatory determination of BP
    • Deflate the cuff pressure 2 mm Hg/s and listen for Korotkoff sounds for an auscultatory reading
  • Step 4: Properly document accurate BP readings
    • Record SBP and DBP to the nearest even number
    • Note the time that the patient had most recently taken BP medication before the reading
  • Step 5: Average the readings
    • Use an average of ≥2 readings from ≥2 occasions.
  • Step 6: Provide BP readings to patient
    • Provide SBP/DBP readings both verbally and in writing, and help the patient interpret the results

Categories of BP Among Adults

  • Normal: SBP<120 mm Hg and DBP <80 mm Hg
  • Elevated: SBP 120-129 mm Hg and DBP <80 mm Hg
  • Hypertension Stage 1: SBP 130-139 mm Hg or DBP 80-89 mm Hg
  • Hypertension Stage 2: SBP ≥140 mm Hg or DBP ≥90 mm Hg
