Arterial Blood Pressure

Systolic Pressure: 120mmHg
Diastolic Pressure: 85mmHg
Mean Pressure: 96 (100)mmHg

 

Mean Arterial Pressure is the most important as regards tissue blood flow.

Arterial Blood Pressure is commonly measured by the auscultatory method.

 
  • Stethoscope is placed over the antecubital artery
  • Blood pressure cuff inflated above systolic pressure
  • As soon as cuff pressure drops below systolic pressure - blood passes through the artery and a tapping sound is heard - Korotkoff sounds.
  • On further reduction the sounds get muffled (or disappears). This corresponds to the diastolic pressure.
