Afebrile Without fever; the body temperature is normal.
alveolus 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. The aorta arises from the upper surface of the left ventricle
apnea temporary cessation of breathing
axilla the armpit
bounding pulse pulse with an increased volume that feels very strong and full.
bradycardia an abnormally slow hear rate (less than 60 BPM)
bradypnea abnormal decrease in the respiratory rate of less than 10 respirations per minute.
celcius scale a temp. scale on on which the freezing point of water is 0 degrees and the boiling point of water is 100 degrees; also called the centigrade scale.
coduction the transfer of energy, such as heat, from one object to another by direct contact
convection transfer of energy, such as heat, through air currents.
crisis sudden falling of an elevated body temp. to normal.
cyanosis blusish discoloration of the skin and mucous membranes
diastole the phase in the cardiac cycle in which the heart arterial wall, which is recorded during diastole.
diastolic pressure the point of lesser pressure on the arterial wall, which is recorded during diastole.
dyspnea shortness of breath or diffficulty in breathing
dysrhyhmia irregular rhythem; also termed arrhythmia
eupnea normal respiration. The rate is 16 to 20 respirations per minute, the rhythm is even and regular, and the depth is normal.
exhalation the act of breathing out
fahrenheit scale a temp scale on which the freezing point of water is 32 degrees and the boiling point of water is 212 degrees.
febrile pertaining to fever
fever a body temp. that is above normal; synonym for pyrexia.
frenulum linguae the midline fold that connects the undersurface of the toungue with the floor of the mouth.
Hyperpnea abnormal increase in the rate and depth of respiration
hyperpyrexia extremly high fever.
hypertension high blood pressure.
hyperventilation abnormally fast and deep type of breathing, usually associated with acute anxiety conditons.
hypopnea abnormal decrease in the rate and depth of respiration
hypotention low blood pressure
hypothermia body temp. that is below normal.
hypoxemia decrease in the oxygen saturation of the bood. Hypoxemia may led to hypoxia
hypxia reduction in the oxygen supply to the tissues of the body
inhalation the act of breathing in
intercostal between the bribs
korotkoff sounds sounds heard during the measurment of blood pressure that are used to determine the systolic and diastolic blood pressure readings.
malaise vague since of body discomfort, weakness, and fatigue that often marks the onset of a disease and continues through the coarse of the illness.
manometer instrument for measuring pressure
meniscus curved surface on a column of liquid in a tube
orthopnea condition in which breathing is easier when an individual is in a sitting or standing position
pulse oximeter computerized device consisting of a probe and monitor used to measure the oxygen saturation of arterial blood
pulse oximetry use of a pulse oximeter to measure the oxygen saturation of arterial blood
pulse pressure difference between the systolic and diastolic pressures
pulse rhythm time interval between heartbeats.
pulse volume the strength of the heartbeat
radiation the transfer of energy, such as heat, in the form of waves.
SaO2 (saturation of arterial oxygen) abbreviation for the percentage of hemoglobin that is saturated with oxygen in arterial blood.
SpO2 (saturation of peripheral oxygen) abbreviation for the percentage of hemoglobin that is saturated with oxygen in arterial bood as measured by a pulse oximeter
sphygmomanometer instrument for measuring aterial blood pressure
stethoscope instrument for amplifying and hearing sounds produced by the body.
systole 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 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 pulse with a decreased volume that feels weak and thin.
