Lab Ex. 45 Pulse Rate & Blood Pressure

Pulse palpation

Pulse pressure The pressure felt as the blood in the artery surges through the point that has pressure applied.

Pulse Points

Pulse points

Popliteal artery

Posterior tibial artery

Dorsalis pedis artery

Blood pressure

Sphygmomanometer

Systolic pressure High Pressure due to ventricular contraction Ex. 120 mmH

Diastolic pressure Low pressure due to ventricular relaxation Ex. 80 mmHg

Sounds of Korotkoff The sounds heard through the stethoscope while taking blood pressure. These are due to systolic pressure pushing blood past the cuff.

Stethoscope

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 pattern formed by the altering pattern of atrial and ventricular contractions and relaxations.

BP = CO X PR The formula to calculate Blood Pressure.

120/80 Normal Blood Pressure

Effects of exercise Exercise increases Blood pressure.
