Systolic pressure
High Pressure due to ventricular contraction
Ex. 120 mmHg
![Page 14: Pulse Rate & Blood Pressure](https://reader037.vdocuments.us/reader037/viewer/2022103007/56814356550346895dafd415/html5/thumbnails/14.jpg)
Diastolic pressure
Low pressure due to ventricular relaxation
Ex. 80 mmHg
![Page 15: Pulse Rate & Blood Pressure](https://reader037.vdocuments.us/reader037/viewer/2022103007/56814356550346895dafd415/html5/thumbnails/15.jpg)
Sounds of Korotkoff
The sounds heard through the stethoscope while taking blood pressure.
These are due to systolic pressure pushing blood past the cuff.

Auscultation
The process of using the stethoscope to listen to each heart valve individually.

Murmur
A swooshing sound produced by the incomplete closing of a heart valve.

Cardiac cycle
The rhythmic contraction (systole) and relaxation (diastole) of the chambers of the heart that corresponds to one heartbeat

Formula to calculate blood pressure
BP = CO x PRBlood pressure = cardiac output x
peripheral resistance
Peripheral resistance is also known as vascular resistance

Normal Blood Pressure
120/80

Effects of exercise on BP
Exercise increases blood pressure. Large groups of muscles need more
oxygen, which causes the heart rate to increase raising blood pressure
