nursing arts

arrhythmia abnormal heart rhythm
arteriosclerosis hardening, thickening and loss of elasticity of the arterial wall
atherosclerosis narrowing of the arterial lumen caused by deposits of fatty plaques along the internal wall of the artery
blood pressure force exerted by the blood against the vessel wall
blood volume total amount of circulating blood
cardiac output amount of blood ejected from the heart per minute
diastolic pressure lowest pressure against wall of the artery, during relaxation of the ventricle of the heart
essential hypertension elevated blood pressure without known cause
hypertension diastolic measurement over 90 mm
hypotension blood pressure lower than the normal range -80mm systolic is necessary for renal perfusion
Korotkoff sound sounds or beats heard through the stethoscope while cuff is being deflated. first sound heard represents systolic, last sound heard represents diastolic
intermittent hypertension blood pressure elevates a small amount over the normal range, from time to time without cause. Patient should be watched for development of hypertensive symptoms
malignant hypertension progressive hypertension which produces severe symptoms and has a poor prognosis if left untreated
meniscus curved surface at the top of column of liquid tube
palpatory blood pressure method of obtaining BP whereby brachial or radial artery is palpated while deflating the BP cuff
peripheral resistance opposing force of the vessel against the blood; pertaining to the health and elasticity of the vessel
sphygmomanometer instrument used for measurement of arterial blood pressure
stethoscope instrument used for auscultation of Korotkoff sounds
stroke volume amount of blood ejected from heart per contraction
systolic represents pressure exerted on arteries during heart contraction
viscosity thickness of blood; ease with which blood flows through the vessel.
crisis rapid drop of body temp to normal
hypothermia body temp that is below average normal range
intermittent temp periods of normal temperature broken by period of elevated temp
lysis gradual return of body temp tomormal
pyrexia an elevated body temp (above normal)
remittent temp an above normal fluctuating temp
apical heart rate the rate obtained by placing stethoscope over the apex of the chest wall and counting
bounding pulse pulse that feels full and strong to the touch
bradycardia a slow heartbeat characterized by a pulse rate that is under 60 beats per minute
elastic pulse pulse with regular alteration of weak and strong beats without changes in cycle
intermittent pulse pulse in which beats are occasionally skipped
irregular pulse pulse that varies in force and frequency
pulse vibration of blood against vessel wall
pulse deficit numerical difference between apical pulse and the radial pulse (apical 101, radial 88, pulse would be 13 BPM)
radial pulse rate pulse rate obtained by placing fingertips over the radial artery at the wrist
thready pulse pulse that feels weak to the touch
apnea absence of breathing
bradypnea below average of slow respiratory rate
cheyne-stokes respiration a gradual increase and then gradual decrease in depth and rate of respirations followed by a period of apnea
dyspnea difficulty or painful breathing
exhalation/expiration act of release of air
hyperpnea increase in respiratory rate and depth
hyperventilation abnormally prolonged and deep breathing usually associated with acute anxiety or emotional tension
hypoxia o2 content in the blood below normal
inhalation/inspiration act of intake of air
orthopnea dyspnea so severe patient needs to sit up to breathe normally
respiration exchange of gases (o2 and co2)
stertorous breathing accompanied by snores
stridor noisy respirations with a harsh or crowing sound( as in croup)
tachypnea rapid respiratory rate
wheeze noisy respirations with a whistling sound
