Vital Signs Terminology - Blood Pressure Terms
| Question | Answer |
|---|---|
| Arrhythmia | Abnormal heart rhythm |
| Arteriosclerosis | Hardening, thickening and loss of elasticity (narrowing) of the arterial wall |
| Atherosclerosis | Narrowing of the arterial lumen caused by deposits of fatty plaques along the internal wall of the artery |
| Blood Pressure | Force exerted by the blood against the vessel wall |
| Blood Volume | Total amount of circulating blood |
| Cardiac Output | Amount of blood ejected from the heart per minute |
| Diastolic Pressure | Lowest pressure against wall of the artery, during relaxation of the ventricle of the heart |
| Essential Hypertension | Elevated blood pressure (in hypertensive range) without known cause |
| Hypertension | Diastolic measurement over 90 mm |
| Hypotension | Blood pressure lower than the normal range- 80 mm systolic is necessary for renal perfusion |
| Korotkoff Sounds | Sounds or beats heard through the stethoscope while cuff is being deflated. First sound heard represents systolic, last sound heard represents diastolic |
| Intermittent Hypertension | Blood pressure elevates a small amount over the normal range, from time to time, without cause. Patient should be watched for development of hypertensive sysmtoms |
| Malignant Hypertension | Progressive hypertension which produces severe symptoms and has a poor prognosis if left untreated |
| Meniscus | Curved surface at the top of column of liquid in a tube |
| Palpatory Blood Pressure | Method of obtaining BP whereby brachial or radial artery is palpated while deflating the BP cuff |
| Peripheral Resistance | Opposing force of the vessel against the blood; pertaining to the health and elasticity of the vessel. |
| Sphygmomanometer | Instrument used for measurement of arterial blood pressure |
| Stethoscope | Instrument used for auscultation of Korotkoff sounds |
| Stroke Volume | Amount of blood ejected from heart per contraction |
| Systolic | Represents pressure exerted on arteries during heart contraction (when at its highest). |
| Viscosity | Thickness of blood; ease with which blood flows through the vessel. |
