Study Notes
Blood Pressure Overview
- Blood pressure is the force exerted by circulating blood on the walls of blood vessels.
- It varies with heart activity: increasing during contraction (systolic) and decreasing when at rest (diastolic).
Systolic Pressure
- Refers to the pressure in arteries during heart contraction.
- Occurs when the left ventricle pushes blood into the arteries.
- Higher readings indicate the heart's workload and can reflect cardiovascular health.
Diastolic Pressure
- Represents the pressure in arteries when the heart is at rest between beats.
- Maintains a baseline pressure necessary for blood flow to tissues.
- Important for assessing cardiovascular health alongside systolic pressure.
Average Blood Pressure Readings
- Represents the overall pressure exerted by blood on arterial walls.
- Essential for determining cardiovascular health and risk of hypertension.
- Typically expressed in millimeters of mercury (mmHg), often noted as systolic over diastolic (e.g., 120/80 mmHg).
