Adventitious Sounds
Abnormal breath sounds heard over the lungs
Antipyretic
Agent that reduces fever
Apical-Radial pulse rate
Pulse rates counted simultaneously for a full minute at the apex of the heart and at the radial artery
Apnea
Absence of breathing
Arrhythmia
Irregular pattern of heart beat. Synonym for dysrhythmia
Auscultation
Listening for sounds within the body
Blood pressure
Force of blood against arterial walls
Bigeminal pulse
Pulse rhythm in which every two pulsations is followed by a pause
Biot's respiration
Respirations of the same depth followed by a period of apnea
Bradycardia
Abnormally slow rate of pulse. <60BPM
Cardiac output
Volume of blood pumped from the left ventricle per minute.
Cheyne-Stokes respiration
gradual increase and then decrease in depth of respirations followed by a period of apnea.
Circadian rhythm
Rhythm that completes a full cycle every 24 hours. synonym for diurnal rhythm.
Conduction
Transfer of heat to another object during direct contact
Constant fever
Body temperature that remains consistently elevated and fluctuates less than 2 degrees C. (3.5F). Sometimes called a continuous fever.
Convection
Dissemination of heat by motion between areas of unequal density.
Core temperature
Temperature of internal areas of the body.
Crisis
Point at which body temperature drops rapidly to normal.
Diastolic pressure
The least amount of pressure exerted on the arterial walls, which occurs when the heart is at rest between ventricular contractions.
Dyspnea
Difficult breathing
Dysrhythmia
Irregular patterns of heartbeat. Synonym for arrhythmia.
Essential hypertension
Abnormally elevated blood pressure with no known cause. Synonym for primary hypertension.
Eupnea
Normal respirations.
Evaporation
Conversion of a liquid to a vapor.
Exhalation
Act of breathing out. Synonym for expiration.
External respiration
Act of lung ventilation, O2 absorption and CO2 elimination
Fever
Elevation above the normal limit of body temperature. Synonym for pyrexia.
Friction rub
Crackling sounds heard in the chest cavity, caused by inflamed pleura rubbing against the chest wall.
Homeothermic
Ability to regulate and maintain body temperature, regardless of the environmental temperature.
Hyperpyrexia
High fever, above 41 degrees C (105.8F). CONVERSION: C temp X 9/5 + 32 = F temp
Hypertension
Blood pressure elevated above the upper limits of normal.
Hypotension
Blood pressure below the lower limits of normal.
Hypothermia
Body temperature below the lower limits of normal.
Inhalation
Act of breathing in. Synonym for inspiration.
Inspiration
Act of breathing in. Synonym for inhalation.
Intermittent fever
Body temperature that alternates between a period of fever and a period of normal or subnormal temperature.
Internal respiration
Act of using O2 by body cells. Synonym for tissue respiration.
Korotkoff sounds
Series of sounds that correspond to changes in blood flow as pressure is released.
Lysis
Gradual return of an elevated body temperature to normal.
Meniscus
Curved surface at the top of a column of liquid in a tube.
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. Synonym for postural hypotension.
Palpitation
Perception of one's own heart beat.
Parallax
Apparent change of position of an object when observed from two different angles.
Peripheral resistance
Restraint to blood flow created by arterial walls in a partial state of contraction.
Poikilothermic
Maintenance of body temperature at or near the temperature of the environment.
Polypnea
Fast respiration rate, synonym for tachypnea.
Postural hypotension
Temporary fall in blood pressure associated with assuming an upright position. Synonym for orthostatic hypotension.
Premature beat
Irregular rhythm in which a heartbeat occurs sooner than the pace at which previous ones were noted.
Primary hypertension
Abnormally elevated blood pressure with no known cause. Synonym for essential hypertension.
Pulse
Wave produced in the wall of an artery with each beat of the heart.
Pulse deficit
Difference between the apical and radial pulse rates.
Pulse pressure
Difference between systolic and diastolic pressure.
Pyrexic
Elevation above the upper limit of normal body temperature. Synonym for fever.
Radiation
Diffusion or dissemination of heat by electromagnetic waves
Rales
Abnormal lung sound described as crackling in nature.
Relapsing fever
Body temperature that returns to normal for at least a day after which fever returns.
Remittent fever
Body temperature that fluctuates several degrees above normal but does not reach normal between fluctuations.
Respiration
Act of breathing in and using oxygen in body cells.
