Term
Definition
apical pulse   pulse taken with a stethoscope and near the apex of the heart.  
🗑
apnea   Absence of respirations; temporary cessation of respirations.  
🗑
arrhythmia   irregular or abnormal rhythm, usually referring to the heart rhythm.  
🗑
aural temperature   taken with a special tympanic thermometer that is placed in the ear or the auditory canal  
🗑
axillary temperature   taken under the armpit under the upper arm less accurate  
🗑
blood pressure   measurement of the force exerted by the heart against the arterial walls when the heart contracts (beats) and relaxes.  
🗑
bradycardia   slow heart rate, usually below 60 beats per minute.  
🗑
bradypnea   slow respiratory rate, usually below 10 respirations per minute.  
🗑
character   the quality of respirations for example deep shallow or labored.  
🗑
cheyne-stokes   periods of difficult breathing followed by periods of no respirations.  
🗑
clinical thermometers   may be used to record temperatures. a slender glass tube containing mercury or alcohol with red dye.  
🗑
cyanosis   bluish color of the skin,nail beds,and/or lips due to an insufficient amount of oxygen in the blood.  
🗑
diastolic   constant pressure in the walls of the arteries when the left ventricle of the heart is at rest or between contractions.  
🗑
dyspnea   difficult or labored breathing  
🗑
electronic thermometers   registers the temperature on a viewer in a few seconds. They can be used to take oral, rectal,axillary, or groin.  
🗑
fever   elevated body temperature, usually above 101f or 38.3c rectally  
🗑
homeostasis   the ideal health state in the human body  
🗑
hypertension   high blood pressure. greater than 140mm Hg systolic and 90 mm Hg diastolic.  
🗑
hyperthermia   occurs when the body temperature exceeds 104F (40C) measured rectally  
🗑
hypotension   low blood pressure pressure less than 90mm Hg and 60 mm Hg.  
🗑
hypothermia   a low body temperature, below 95F (35C) measured rectally  
🗑
oral temperature   temperature taken in the mouth.This is the most common and convenient method of obtaining a temperature. eating, drinking, or smoking can alter the temperature.  
🗑
orthopnea   severe dyspnea in which breathing is very difficult in any position other than sitting erect, or standing.  
🗑
pulse   the pressure of the blood felt against the wall of the artery as the heart contracts and relaxes, or beats  
🗑
pulse deficit   a condition that occurs with some heart conditions. In some cases the heart is weak and does not pump enough blood to produce a pulse or the heart pumps too fast and there is not enough time for the heart to fill with blood.  
🗑
pulse pressure   is an important indicator of the health and tone of arterial walls. normal rate for pulse pressure in adults is 30 to 50mm Hg.  
🗑
pyrexia   another term for fever  
🗑
rale   bubbling or noisy sounds caused by fluid or mucus in the air passages  
🗑
rate   the number of beats per minute.  
🗑
rectal temperature   are taken in the rectum. This is an internal measurement and is the most accurate  
🗑
respirations   the breathing rate of the patient.  
🗑
rhythm   refers to regularity  
🗑
sphygmomanometer   an instrument used to measure blood pressure in millimeters of mercury (mm Hg). The main types are mercury, aneroid, and electronic.  
🗑
stethoscope   an instrument used to listen to internal body sounds.  
🗑
systolic   pressure occurs in the walls of the arteries when the left ventricle of the heart is contracting and pushing blood into the arteries.  
🗑
tachycardia   a pulse rate over 100 beats per minute (except in children)  
🗑
tachypnea   rapid, shallow respiratory rate above 25 respirations per minute.  
🗑
temperature   measurement of the balance between heat lost and heat produced by the body  
🗑
temporal scanning thermometer   specialized electronic thermometers that measure the temperature in the temporal artery of the forehead.  
🗑
temporal temperature   A special temporal scanning thermometer is passed in a straight line across the forehead, midway between the eyebrows and upper hairline.  
🗑
tympanic thermometer   specialized electronic thermometers that record the aural temperature in the ear.  
🗑
vital signs   various determinations that provide information about basic body conditions of the patient.  
🗑
volume   refers to strength  
🗑
wheezing   difficult breathing with a high pitched whistling or sighing sound during expiration caused by narrowing of the bronchioles.  
🗑
