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”
