| Question | Answer |
|---|---|
| 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 |
