Terms Definitions
apical pulse

Heartbeat as measured with the bell or disk of the stethoscope placed over the apex of the heart; represents the actual beating of the heart. Most authentic of all pulses.
listen for sounds within the body to evaluate the condition of heart, lungs, pleura, intestines, or other organs or to detect fetal heart tones
Blood Pressure

Pressure exerted by the circulating volume of blood on the arterial walls, veins, and chambers of the heart.
if pulse is slower than 60 beats per minute, the patient

A slow respiratory rate of fewer than 12 breaths per minute.
Cheyne-Stokes respirations
are an abnormal pattern of respiration characterized by alternating periods of apnea and deep, rapid breathing. The periods of apnea increase as time goes on
diastolic pressure

The second number recorded in the blood pressure reading; represents the minimum level of blood pressure measured between the contractions of the heart.
Shortness of breath or difficulty in breathing; may be caused by disturbances in the lungs, certain heart conditions, and hemoglobin deficiency

Any disturbance or abnormality in a normal rhythmic pattern, specifically irregularity in the normal rhythm of the heart; also called arrhythmia.

Body temperature above normal.

Occurs when the elevated blood pressure is above normal.

Condition of abnormally high body temperature.

Occurs when the blood pressure is below normal.

Condition of abnormally low body temperature.
korotkoff sounds

Sounds heard while measuring blood pressure when using a sphygmomanometer and stethoscope.
orthostatic hypotention

A drop of 25 mm Hg in systolic pressure and a drop of 10 mm Hg in diastolic pressure when moving from a lying to sitting position.

A rhythmic beating or vibrating movement; regular recurrent expansion and contraction of an artery produced by waves of pressure caused by the ejection of blood from the left ventricle of the heart as it contracts.
pulse deficit

A condition that exists when the radial pulse rate is less than the ventricular rate as auscultated at the apex of the heart.
pulse pressure

Difference between the systolic and diastolic blood pressures, usually 30 to 40 mm Hg.
the taking in of oxygen, its utilization in the tissues, and the giving off of carbon dioxide; the act of breathing, i.e., inhaling and exhaling)

Device for measuring arterial blood pressure.

Instrument placed against patient's body to hear heart, lung, or bowel sounds.

The number or reading that represents ventricles contracting, forcing blood into the aorta and pulmonary arteries. In blood pressure readings, it is the higher of the two readings.

An abnormal condition in which the myocardium contracts regularly but at a rate greater than 100 beats per minute.

An abnormally rapid rate of breathing.

Relative measure of sensible heat or cold.

Membranous eardrum.
vital signs

Measurement of temperature, pulse, respiration, and blood pressure.
