Study Notes
Blood Pressure (BP)
- BP is the pressure exerted by blood against the walls of blood vessels.
- It's a crucial measure of cardiovascular function.
- Measured as systolic (highest pressure) over diastolic (lowest pressure), in mmHg.
- Normal resting BP is typically below 120/80 mmHg.
- Factors affecting BP include blood volume, vascular resistance, and heart rate.
Cardiac Output (CO)
- CO is the volume of blood pumped by the heart per minute.
- Calculated as heart rate (HR) multiplied by stroke volume (SV).
- HR is the number of heartbeats per minute.
- SV is the volume of blood ejected from the heart with each beat.
Hypertension
- Hypertension is high blood pressure (≥130/80 mmHg, as of 2017).
- Current definition results in more people being classified as hypertensive.
- Lifestyle changes may be sufficient, without necessarily needing medication.
- Can contribute to cardiovascular disease.
Measuring BP
- Indirect measurements use a sphygmomanometer and stethoscope.
- Sounds (Korotkoff phases) created by blood flow through the artery are listened to.
- Cuff size is important for accurate BP measurements.
- Arm should be free of clothing and in a relaxed position.
Factors impacting BP measurements
- Body position (e.g., supine vs. standing) can influence BP.
- Stress (white coat syndrome) can increase readings.
- Hydration and exercise affect BP.
- Medical conditions affect it as well.
