    1. Blood pressure & heart disorder Notes

    2. (1) Pulse Pressure wave that travels through arteries Result of contraction and relaxation of artery Pulse Rate should = Heart Rate Could vary if blood vessel filled with fatty deposits or damaged interior walls

    3. (2) Blood Pressure Pressure blood exerts against vessel walls Keeps blood circulating Ventricles Contract: Blood forced into arteries Arteries expand as blood travels through Blood moves high ? low pressure Blood continues to move into areas without blood Eventually moves back to heart (when heart empties out)

    4. (3) Measuring Blood Pressure Systolic Pressure Pressure in arteries Peak of ventricular contraction Diastolic Pressure Pressure in ventricles Relaxed ventricles Measuring Blood Pressure Cuff is inflated/tightened until cuff pressure is greater than systolic pressure Blood flow in arm ceases No pulse (heard + felt) Pressure in cuff is reduced ? listen for pulse sounds Systolic Blood Pressure = first soft tapping sounds Diastolic Blood Pressure = no more tapping sounds, constant flow Expressed: Systolic over Diastolic
