Abstract: With the increase in the number of senior citizens and chronic diseases, the number of elderly patients who need constant assistance has increased. One key point of all critical care for elderly patient is the continuous monitoring of their vital signs. So, we can use the purpose of Remote health care monitoring unit for elderly patient using GSM technology is used to identify the emergency of the patient. In this monitoring unit, we can monitor the range of heart beat, blood pressure, body temperature, oxygen level and glucose trips indicator. Here, heart beat is measured by electrodes, blood pressure is measured by pressure sensor, body temperature is measured by thermistor. The flash technology of PIC microcontroller is used to store the data for transmission. The data can be transmitted by GSM and received by GPS. It provides flexible and powerful patient surveillance through wearable devices at anytime and anywhere. The increasing feasibility and convenience of monitoring unit have several significant challenges for healthcare providers, policy makers, hospitals and patients.
