Lab 1 Terms

afebrile

Without fever

antipyretic

Pertaining to a substance, such as a medication, that reduces fever

apical pulse

Measurement of the heartbeat taken with the stethoscope placed over the apex of the heart.

bradycardia

An abnormality in heart rate in which the heart contracts steadily at a rate less than 60 contractions/min.

bradypnea

Breathing that is normal in rate but abnormally slow (less than 12 breaths/min).

core temperature (Perry 1158)

diastolic pressure

The lower blood pressure measurement, which reflects the pressure consistently exerted within the arterial system during the period of ventricular relaxation.

dyspnea

Difficulty breathing.

dysrhythmia

An irregular, fast, or slow heart rhythm.

febrile

Pertaining to or characterized by fever or an elevation in body temperature.

heatstroke

Condition characterized by core body temperature of 45�C (116�F).

hypertension

Condition characterized by an elevated blood pressure persistently exceeding 150/90 mm Hg.

hyperthermia

Condition characterized by body temperature over 38�C (100.4�F).

hypotension

Condition characterized by a low blood pressure that is inadequate to perfuse and oxygenate body tissue.

hypothermia

Condition characterized by body temperature below 36�C (96.8�F).

orthopnea

An abnormal condition in which a person must sit or stand to breathe deeply or comfortably.

orthostatic hypotension

A drop in blood pressure of 15 mm Hg or more when an individual rises from a sitting to a standing position.

oximetry

Procedure used to measure amount of oxygenated hemoglobin.

oxygen saturation

Amount of hemoglobin that is fully saturated with oxygen expressed as percentage of total available hemoglobin.

postural hypotension

Condition in which a normotensive person becomes light-headed or dizzy and experiences low blood pressure when rising to an upright position.

premature ventricular contraction (PVC)

A cardiac dysrhythmia characterized by a ventricular contraction preceding the expected contraction; it appears on an electrocardiogram as an early, wide QRS complex without a preceding P wave.

pulse deficit

Condition characterized by difference between apical and peripheral pulse rate that results in a lack of peripheral perfusion.

pyrexia

Fever. An elevation of the body temperature above the normal range.

sphygmomanometer

Device used for noninvasive measurement of arterial blood pressure. Consists of cuff, air bladder, inflation bulb, and gauge to indicate amount of air pressure being exerted.

systolic pressure

The higher blood pressure measurement. Reflects pressure within the arterial system during the period of ventricular contraction (systole).

tachycardia

An abnormality in heart rate in which the myocardium contracts regularly but at a rate over 100 beats/min.

tachypnea

Condition characterized by respiratory rate greater than 20 breaths/min.

thermoregulation

Ability to control temperature within acceptable range.

tympanic

Pertaining to a structure that resonates when struck. Drumlike.

vasoconstriction

Narrowing of the lumen of any blood vessel, especially the arterioles and the veins in the blood reservoirs of the skin and abdominal viscera.

vasodilation

An increase in the diameter of a blood vessel caused by inhibition of its vasoconstrictor nerves or stimulation of dilator nerves.
