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) and blood pressure, but may also include other measurements. Vital signs often vary by age.There are three vital signs which are standard in most medical settings:body temperature,pulse rate (or heart rate),blood pressure. The equipment needed is a thermometer, a sphygmomanometer, and a watch. Though a pulse can often be taken by hand, a stethoscope may be required for a patient with a very weak pulse.In this research paper, we have introduced the ANDROID operating system to measure the vital signs such as Heart rate, blood pressure and temperature.s Heart rate, blood pressure and temperature.
