Group of the 4 6 important medical signs that indicate the status of the body's vital functions

Vital signs (also known as vitals) are a group of the four to six most crucial medical signs that indicate the status of the body's vital (life sustaining) functions. These measurements are taken to help assess the general physical health of a person, give clues to possible diseases, and show progress toward recovery. The normal ranges for a person's vital signs vary with age, weight, sex, and overall health. There are four primary vital signs: body temperature, blood pressure, pulse (heart rate), and breathing rate (respiratory rate), often notated as BT, BP, HR, and RR. However, depending on the clinical setting, the vital signs may include other measurements called the "fifth vital sign" or "sixth vital sign." Early warning scores have been proposed that combine the individual values of vital signs into a single score. This was done in recognition that deteriorating vital signs often precede cardiac arrest and/or admission to the intensive care unit. Used appropriately, a rapid response team can assess and treat a deteriorating patient and prevent adverse outcomes.

Temperature recording gives an indication of core body temperature, which is normally tightly controlled (thermoregulation), as it affects the rate of chemical reactions. Body temperature is maintained through a balance of the heat produced by the body and the heat lost from the body. Temperature can be recorded in order to establish a baseline for the individual's normal body temperature for the site and measuring conditions. Temperature can be measured from the mouth, rectum, axilla (armpit), ear, or skin. Oral, rectal, and axillary temperature can be measured with either a glass or electronic thermometer. The main reason for checking body temperature is to solicit any signs of systemic infection or inflammation in the presence of a fever. Fever is considered temperature of 37.8 °C (100.0 °F) or above. It may also be called "heart rate". In addition to providing the heart rate, the pulse should also be evaluated for strength and obvious rhythm abnormalities. A child aged 1–⁠3 years old can have a heart rate of 80–⁠130 bpm, a child aged 3–⁠5 years old a heart rate of 80–⁠120 bpm, an older child (age of 6–10) a heart rate of 70–⁠110 bpm, and an adolescent (age 11–⁠14) a heart rate of 60–105 bpm. In contrast to the traditional vital signs, these measurements are not useful for assessing acute changes in state because of the rate at which they change; however, they are useful for assessing the impact of prolonged illness or chronic health problems. The definition of vital signs may also vary with the setting of the assessment. Emergency medical technicians (EMTs), in particular, are taught to measure the vital signs of respiration, pulse, skin, pupils, and blood pressure as "the 5 vital signs" in a non hospital setting.

Monitoring of vital parameters most commonly includes at least blood pressure and heart rate, and preferably also pulse oximetry and respiratory rate. Multimodal monitors that simultaneously measure and display the relevant vital parameters are commonly integrated into the bedside monitors in intensive care units, and the anesthetic machines in operating rooms. These allow for continuous monitoring of a patient, with medical staff being continuously informed of the changes in the general condition of a patient. While monitoring has traditionally been done by nurses and doctors, a number of companies are developing devices that can be used by consumers themselves. These include Cherish Health, Scanadu and Azoi.
