Vital Signs Terminology. - Blood Pressure

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
