Manual Blood Pressure

  • Wash hands, introduce self and check patient name and DOB.
  • Explain to the patient that this might be uncomfortable but if they cannot tolerate it, let you know.  Gain consent.
  • Position the patient’s arm level with their heart and relaxed.  This is most easily done by putting it on a pillow.
  • Without the use of the stethoscope first:
    • Wrap the sphygmomanometer cuff around the patients bicep belly with the artery arrow overlying the brachial artery.
    • With your fingers feeling for the radial pulse at the wrist, inflate the cuff until this disappears.  This estimates systolic BP. Deflate the cuff
    • Next using the stethoscope (whether to use the bell or diaphragm is debated) over the cubital fossa, inflate the cuff to the estimated SBP +20 mmHg and slowly deflate the cuff at around 2 mmHg/sec.
      • At the SBP, you should begin to hear pulsatile noises (Korsakoff sounds).
      • At the DBP, these sounds disappear.
    • Deflate the cuff and record SBP/DBP.
