Vital signs, normally called as signs of life, are measures of various physical and physiological statistics of patients often taken by a physician or healthcare professional in order to assess the most basic functions of body.
Four primary vital signs include respiratory rate (rate of breathing), temperature, heart beat, and blood pressure Vital signs helps healthcare professional to asses and monitor patient’s conditions and provide critical information needed to make life saving treatment decisions.
Vital signs (signs of life) can be measured, observed and monitored by a physician, nurse or health care professionals. Vital signs measurements provide a baseline for a patient’s treatments. Abnormalities of heart rate are diagnosed by analyzing the pulse rate and blood pressure of a patient. Rate of heart beat is raised during conditions such as fever and lowered by conditions such as shock or elevated intracranial pressure (pressure that occurs within the cranium).
The average heart rate of an adult is approximately 72 beats per minute. A normal body temperature of a healthy person is 98.6 degrees Fahrenheit or 36.5 degrees Celsius but this can slightly vary from person to person and also depends where the temperature is measured and whether the temperature of a person is measured with mercury or digital thermometer. Blood pressure of a patient is recorded by sphygmomanometer. Blood pressure is recorded with the systolic pressure and diastolic pressure (e.g. 120/80).A normal blood pressure of a healthy person should be less than (120/80) mm Hg.
Vital signs are normally recorder after regular interval, or as required by patients condition. These vital signs (signs of life) are then compared with healthy persons vital signs of same age and physical conditions and based on these results further actions are taken.
