celsius scale a temperature scale on which the freezing pointof water is 0 degrees and the boiling point of water is 100 degrees ; also called the centigrade scale
fahrenheit scale a temperature scale on which the freezing point is 32 degrees and the boiling point of water is 212 dregrees
korotkoff sounds sounds heard during the measurement of blood pressure that are used to determine the systolic and diastolic blood pressure reading
SaO2 Abbrevatition of the precentage of hemoglobin that is staurated with oxygen in arterial blood;strands for stauration of arterial oxygen
Sp02 abbreviation for the percentage of hemoglobin that is saturated with oxygen in arterial blood as measured by a pulse oximeter; stands for saturation of peripheral oxygen
adventitious sounds abnormal breath sounds
afebrile without fever; the body temperature is normal
alveolus A thin-walled air sac of the lungs in which the exchange of oxygen and carbon dioxide takes place.
antecubital space The space located at the front of the elbow.
antipyretic An agent that reduces fever.
aorta The major trunk of the arterial system of the body; this rises from the upper surface of the left ventricle.
apnea The temporary cessation of breathing.
axilla The armpit.
bounding pulse a pulse with an increased volume that feels very strong and full
bradycardia an abnormally slow heart rate, less than 60 beats per minute
bradypnea an abnormal decrease in the respiratory rate of less than 10 respirations per minute
conduction the transfer of energy, such as heat, from one object to another by direct contact
convection the transfer of energy, such as heat, through air currents
crisis a sudden falling of an elevated body temperature to normal
cyanosis a bluish discoloration of the skin and mucous membranes
diastole the phase in the cardiac cycle in which the heart relaxes between contractions
diastolic pressure the point of lesser pressure on the arterial wall, which is recorded by diastole
dyspnea shortness of breath or difficulty in breathing
dysrhythmia an irregular rhythm; also termed arrhythmia
eupnea normal respiration; the rate is 16-20 respirations per minute, the rhythm is even and regular and the depth is normal
exhalation the act of breathing out

hyperventilation an abnormally fast and deep type of breathing, usually associated with acute anxiety conditions
hypopnea an abnormal decrease in the rate and depth of respiration
hypotension low blood pressure
hypothermia a body temperature that is below normal
hypoxemia a decrease in the oxygen satuation of the blood; leads to hypoxia
hypoxia a reduction in the oxygen supply to the tissues of the body
inhalation the act of breathing in
intercostal between the ribs
malaise a vague sense of body discomfort, weakness, and fatigue that often marks the onset of a disease and continues through the course of the illness
manometer an instrument for measuring pressure
meniscus the curved surface on a column of liquid in a tube
orthopnea the condition in which breathing is easier when an individual is in a sitting or standing position
pulse oximeter a computerized device consisting of a probe and monitor used to measure the oxygen saturation of arterial blood
pulse oximetry the use of a pulse oximeter to measure the oxygen saturation of arterial blood
pulse pressure the difference between the systolic and diastolic pressures
pulse rhythm the timer interval between heartbeats
pulse volume the strength of the heartbeat
radiation the transfer of energy, such as heat, in the form of waves
sphygomanometer an instrument for meauring arterial blood pressure
stethoscope an instrument for amplifying and hearing sounds produced by the body
systole the phase in the cardiac cycle in which the ventricles contract, sending blood out of the heart and into the aorta and pulmonary aorta
systolic pressure the point of maximum pressure on the arterial walls, which is recorded during systole
tachycardia an abnormally fast heart rate, more than 100 beats per minute
tachypnea an abnormal increase in the respiratory rate of more than 20 respirations per minute
thready pulse a pulse with a decreased volume that feels weak and thin
