Blood Pressure - (answers)A measurement of the force circulating blood exerts on
the interior walls of blood vessels.
Measured in mmHg.
Systole - (answers)The contraction phase of the cardiac cycle. During this phase
blood is driven into the aorta and pulmonary arteries.
Diastole - (answers)The relaxation phase of the cardiac cycle where the heart
muscle is relaxed and the chambers of the heart fill with blood.
Cardiac Output (CO) - (answers)The volume of blood ejected by the heart
ventricles in one minute; calculated by multiplying the stroke volume and pulse
rate of the heart.
Stroke Volume - (answers)Volume of blood ejected by the left ventricle during
one contraction.
Viscosity - (answers)The resistance of a liquid to flow, refers to the thickness of
the blood.
,2|Page
Peripheral Vascular Resistance - (answers)The total resistance to flow of blood in
the vascular bed, the ability of the vessels to accommodate increased blood flow
without also increasing resistance or blood pressure.
Contractility - (answers)The force required to eject blood from the left ventricle,
refers to the heart's ability to contract efficiently.
Preload - (answers)The blood remaining in the left ventricle at the end of diastole
causing it to stretch.
Sphygmomanometer - (answers)Instrument used to measure arterial blood
pressure (blood pressure cuff).
Stethoscope - (answers)An instrument used to listen to sounds produced by the
body.
Korotkoff Sounds - (answers)A series sounds created by movement of blood
through a partially compressed vessel during a manual blood pressure
assessment.
Hypertension - (answers)A blood pressure that is above the expected reference
range.
Hypotension - (answers)A blood pressure that is below the expected reference
range.
, 3|Page
Orthostatic Hypotension - (answers)A decrease in blood pressure that occurs
upon standing, especially from a lying or sitting position. A significant drop in the
blood pressure caused by a change in position.
Tachycardia - (answers)Heart rate above the expected reference range.
Bradycardia - (answers)A heart rate that is less than the expected reference
range.
Apical Pulse - (answers)The heart rate that is heard or felt at the apex of the
heart, which is located medially to the midclavicular line at the fifth intercostal
space.
Temporal Pulse - (answers)Beating or throbbing palpated over the temporal
artery located on the temple.
Brachial Pulse - (answers)Beating or throbbing felt over the brachial artery,
usually palpated in the antecubital space; it is used to assess the quality of
perfusion.
Radial Pulse - (answers)Beating or throbbing felt over the radial artery, usually
palpated over the groove along the thumb side of the inner wrist.
