Normally it measures 120 mm Hg Dicrotic Notch TheDicrotic Notch represents the interruption ofblood flow due to the brief backflow of blood thatcloses the aortic semilunar valve when the.
ventricles relax Diastolic Pressure Diastolic Pressure is the lowest pressure in the It result when the ventricles are relaxed and isusually around 80 mm Hg .
Blood Pressure Sounds A cuff is inflated to constrict an artery sothat no blood flows As the cuff pressure is slowly released butthe artery is still partially constricted blood.
flow begins again Sounds can be heard because the bloodflows violently causing audible sounds When the artery is fully open the bloodflows freely and the sounds disappear .
Checking Blood Pressure The first sounds that are heard indicatesystolic pressure top number When the sounds stop diastolic pressurehas been reached bottom number .
