Breaking of a fever
Antipyretics
Drugs that reduce fevers
Auscultatory gap
Temporary disappearance of sound
Basal metabolic rate
Heat produced by the body at absolute rest
Blood pressure
The force exerted on the walls of an artery by the pulsing blood under pressure from the heart
Bradycardia
Slow rate below 60 beats per minute in adults
Cardiac output
The volume of blood pumped by the heart during 1 minute
Conduction
Transfer of heat from one object to another with direct contact
Convection
Transfer of heat away by air movement
Core temperature
Temp of the deep tissues
Diaphoresis
Visible perspiration primarily occurring on the forehead and upper thorax
Diastolic pressure
The minimal pressure exerted against the arterial walls at all times
Diffusion
The movement of oxygen and carbon dioxide between the alveoli and the red blood cells
Dysrhythmia
An interval interrupted by an early or late beat or a missed beat
Eupnea
Sighs that interrupt the normal rate and depth of ventilation
Evaporation
The transfer of heat energy when a liquid is changed to a gas
Febrile
Having a fever
Frostbite
When the body is exposed to subnormal temperatures
Heat Exhaustion
When profuse diaphoresis results in excess water and electrolyte loss
Hematocrit
Percentage of red blood cells in the blood
Hyperthermia
An elevated body temp related to the bodys inability to promote heat loss or reduce heat production
Hypotension
When the systolic blood pressure falls to 90 mm Hg or below
Hypothalamus
Controls the body temp
Hypothermia
Heat loss during prolonged exposure to cold overwhelming the bodys ability to produce heat
Hypoxemia
Low levels of arterial O2
Malignant hyperthermia
A hereditary condition of uncontrolled heat production
Orthostatic hypotension
Occurs when a normotensive person develops symptoms and low blood pressure when rising to an upright position
Perfusion
The distribution of red blood cells to and from the pulmonary capillaries
Pulse deficit
An inefficient contraction of the heart that fails to transmit a pulse wave to the peripheral pulse site
Pulse pressure
The difference between systolic and diastolic pressure
Radiation
Transfer of heat from one surface of one object to the surface of another object without direct contact
Tachycardia
An abnormal elevated heart rate above 100 beats per min
Thermoregulation
Physiological and behavioral mechanisms regulate the balance between heat lost and heat produced
Ventilation
The movement of gases in and out of the lungs
