CH25 Vital Signs

afebrile

a condition in which the body temperature is not elevated

apnea

absence of breathing

auscultatory gap

period of diminished or absent Korotkoff sounds; it occurs during the manual measurement of blood pressure in the later part of phase 1 and during phase 2

blood pressure

force of blood against arterial walls

bradycardia

slow heart rate

diastolic pressure

least amount of pressure exerted on arterial walls. which occurs when the heart is at rest between ventricular contractions

dyspnea

difficult or labored breathing

dysrhythmia

an abnormal cardiac rhythm

eupnea

normal respirations

febrile

condition in which the body temperature is elevated

fever

elevation above the upper limit of normal body temperature; synonym for pyrexia

hypertension

blood pressure elevated above the upper limit of normal

hyperthermia

high body temperature

hypotension

blood pressure below the lower limit of normal

hypothermia

low body temperature

Korotkoff sounds

series of sounds that correspond to changes in blood flow through an artery as pressure is released

orthopnea

type of dyspnea in which breathing is easier when the patient sits or stands

orthostatic hypotension

temporary fall in blood pressure associated with assuming an upright position; synonym for postural hypotension

pulse

wave produced in the wall of an artery with each beat of the heart

pulse deficit

difference between the apical and radial pulse rates

pulse pressure

difference between systolic and diastolic pressures

pyrexia

elevation above the upper limit of normal body temperature; synonym for fever

respirations

gas exchange between the atmospheric air in the alveoli and blood in the capillaries

systolic pressure

highest point of pressure on arterial walls when the ventricles contract

tachycardia

rapid heart rate

tachypnea

rapid rate of breathing

temperature

refers to the hotness or coldness of a substance

vital signs

body temperature, pulse and respiratory rates, and blood pressure; synonym for cardinal signs
