Vital Signs Terminology. - Blood Pressure
| Question | Answer |
|---|---|
| Blood Pressure | Force exerted by the blood against the vessel wall |
| Cardiac Output | Amount of blood ejected from the heart per minute |
| Peripheral Resistance | Opposing force of the vessel against the blood; pertaining to the health and elasticity of the vessel |
| Stroke Volume | Amount of blood ejected from heart per contraction |
| Pulse Pressure | Numerical difference between Systolic BP and Diastolic BP |
| Blood Volume | Total amount of circulating blood |
| Cardiac Output | Amount of blood ejected by the heart per minute |
| Resistance | Opposing force of the vessel against the blood; pertaining to the health and elasticity of the vessel |
| Viscosity | Thickness of blood; ease with which blood flows through vessel |
| Hormones | ADH - Anti Diuretic Hormones (water retention) Aldosterone (ALST) - causes sodium retention (increase B.P. |
| Normal range of Systolic BP | anything from 80 - 120 |
| Normal range of Diastolic BP | anything from 0 - 80 |
| Blood pressure measured in what? | mmHg (millimeters of Mercury) |
| What method is used in obtaining BP using the stethoscope? | Auscultatory |
| What is meant by "Vital Signs"? | T - Temperature P - Pulse (Heart Rate) R - Respiratory BP - Blood Pressure |
| Arteriosclerosis | Hardening, thickening and loss of elasticity (narrowing) of the arterial wall. |
| Phase I of Blood Pressure | Blood begins to trickle through. Begin to hear korotkoff sounds - systolic. |
| Phase II of Blood Pressure | Blood continues to flow. Bouncing off walls - korotkoff sounds continue. "swish" sounds in phase II sounds stop - "auscultatory gap" (this is not common) |
| Phase III of Blood Pressure | Everything continues - however - if you don't pump the cuff up high enough - you'll miss patients who have high blood pressure or 30-40-50- mm of mercury off. You could think the first sounds you hear (systolic) would be after the "auscultatory gap". |
| Phase IV of Blood Pressure | Sounds continue - softer - quieter |
| Phase V | Sounds stop - diastolic |
