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 arterial/vessel wall.
When the heart contracts and relaxes
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 80mm.
Hypotension
Blood pressure lower than the normal range - 80mm 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 symptoms.
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 ther 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.
