Vital signs are measures of various physiological statistics, often taken by health professionals, in order to assess the most basic body functions. Vital signs are an essential part of a case presentation. The act of taking vital signs normally entails recording Body temperature, Pulse rate (or heart rate), Blood pressure, and Respiratory rate
lowest in morning
highest in evening
oral 96.8-99.8 F
rectal higher (0.5 to1.0 F)
Febrile, pyrexia or hyperthermia
Heart not pumping enough blood
Interference with oxygen supply (respiration)
Blood pressure (BP) is the pressure exerted by circulating blood on the walls of blood vessels, and is one of the principal vital signs. For each heartbeat, BP varies between a maximum (systolic) and a minimum (diastolic) pressure. The mean BP decreases as the circulating blood moves away from the heart through arteries, has its greatest decrease as the blood moves through the small arteries and arterioles, and continues to decrease as the blood moves through the capillaries and back to the heart through veins.
