Unit 1 Terminology Flashcards
Afebrile
Without fever
Antipyretics
Medications that reduce fever
Auscultatory Gap
Disappearance of sound when obtaining a BP; typically occurs between the first and second Korotkoff sounds
Blood Pressure
Force exerted on the walls of an artery by the pulsing blood under pressure from the heart
Bradycardia
Slower than normal heart rate; heart contracts fewer than 60 times/min
Capnography
Measurement of exhaled CO2 throughout exhalation
Conduction
Transfer of heat from one object to another with direct contact (lose heat)
Convection
Transfer of heat away from air movement (ceiling fan)
Core Temperature
Temperature of deep structures of the body
Diaphoresis
Visible perspiration primarily occurring on the forehead and upper thorax
Diastolic Pressure
Pertaining to diastole, or the blood pressure at the instant of maximum cardiac relaxation; the pressure of the blood in the arteries when the heart is filling
Dysrhythmia
Deviation from the normal pattern of the heartbeat; interval interrupted by an early, missed, or late beat indicate abnormal rhythm
Eupnea
Normal breathing; normal respirations that are quiet, effortless, and rhythmical
Evaporation
Transfer of heat energy when a liquid is changed to a gas
Febrile
Pertaining to or characterized by an elevated body temperature
Fever
Elevation in the hypothalamic set point so that body temperature is regulated at a higher level
Fever of Unknown Origin (FUO)
Fever with an unknown cause
Frostbite
Body is exposed to subnormal temperatures. Ice crystals form inside the cells, and permanent circulatory and tissue damage occurs
Heat Exhaustion
Abnormal condition caused by depletion of body fluids and electrolytes resulting from exposure to intense heat or the inability to acclimatize to heat
Heatstroke
Continued heat exposure to extreme heat that raises the core body temperature to 40.5C (105F) or higher
Hematocrit
Percentage of red blood cells in the blood, determines blood viscosity
Hypertension
Disorder characterized by an elevated blood pressure persistently exceeding 120/80 mm Hg
Hypotension
Abnormal lowering of blood pressure that is inadequate for normal perfusion and oxygenation of tissues
Hypothermia
Abnormal lowering of body temperature below 35C, or 95F, usually caused by prolonged exposure to cold
