Terms Flashcards
afebrile
“without fever” - a person with a normal body temperature
apnea
periods during which there is no breathing
blood pressure
the force of the moving blood against arterial walls
bradycardia
slow pulse rate (<60 bpm for adult)
bradypnea
slow rate of breathing
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
irregular pattern of heartbeats
eupnea
normal respiration (12-20 for adults)
febrile
a person with a fever
hypertension
blood pressure elevated about he upper limit of normal
hyperthermia
high body temperature (>105.8 F)
hypotension
blood pressure below the lower limit of normal
hypothermia
low body temperature (<97.0 F)
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
pulse
wave produced in the wall of an artery with each beat of the heart (normal is 60-100 bpm for adolescents & adults)
pulse deficit
difference between the apical and radial pulse rates
pulse pressure
difference between systolic and diastolic pressures
respiration
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 (100-180 for adult)
tachypnea
increased respiratory rate
