Why this matters

Set up carefully, then copy both numbers exactly.

Quick tips

  • Record systolic and diastolic exactly as displayed.
  • Do not remove the cuff until the reading has finished.
  • If the cuff goes over 200 mm Hg, stop and use the other arm.

Common mistakes

  • Rounding or misreading the numbers when recording.
  • Using a cuff that does not fit the arm.
  • Removing the cuff before the reading finishes.
  • Washing hands after recording instead of before.
