Vital signs

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. The aorta arises 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
Celsius scale a temperature scale on which the freezing point of water is zero and the boiling point is one hundred; also called centigrade scale
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 during diastole
dyspnea shortness of breath or difficulty in breathing
dysrhythmia an irregular rhythm; 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 the temperature scale on which the freezing point is 32 degrees and the boiling point is 212 degrees
febrile pertaining to fever
fever a body temperature that is above normal; synonym for pyrexia
frenulum linguae the midline fold that connects the undersurface of the tongue with the floor of the mouth
hyperpnea an abnormal increase in the rate and depth of respiration
hyperpyrexia an extremely high fever
hypertension high blood pressure
hyperventilation an abnormally fast and deep type of breathing, usually associated with acute anxiety problems
hypopnea an abnormal decrease in the rate and depth of respiration
hypotention low blood pressure
hypothermia a body temperature that is below normal
hypoxemia a decrease in the oxygen saturation of the blood, may lead to hypoxia
hypoxia a reduce in the oxygen supply to the tissues of the body
inhalation the act of breathing in
intercostal between the ribs
korotkoff sounds sounds heard during the measurement of blood pressure that are used to determine the systolic and diastolic blood pressure readings
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
orthpnea 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 a 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 systolic and diastolic pressures
pulse rhythm the time interval between heartbeats
radiation the transfer of energy, such as heat, in the form of waves
SaO2 abbreviation for the percentage of hemoglobin that is saturated with oxygen in arterial blood as measured by a pulse oximeter
stethoscope an instrument used 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
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
