Systolic Pressure
The blood pressure during ventricular contraction when it is relatively high.
Diastolic Pressure
The blood pressure during ventricular relaxation when it is relatively low.
Sphygmomanometer
An instrument used to measure blood pressure.
Stethoscope
A device used to listen to sounds made by the heart and blood flow.
The first audible sound during blood pressure measurement indicates __________.
The systolic pressure.
The moment when sounds are no longer audible during blood pressure measurement indicates __________.
The diastolic pressure.
What happens during the contraction of both the atria and ventricles?
Blood is forced through the arteries into different parts of the body.
What creates the tapping sound during blood pressure measurement?
The spurting of blood through the constricted artery during ventricular contraction.
How is systolic pressure measured?
applying pressure to the artery through the inflation of a cuff
How is diastolic pressure measured?
after continuing to let the air out the cuff/occurs after ventricular relaxation
