A patient in a coma is unconscious and unable to communicate. A real-time monitoring system called the IoT-Based Healthcare Monitor for Coma Patients is intended to provide coma patients with a safe and secure environment. The system continually monitors the patient's vital signs and movement in the bed using a variety of sensors, including heart rate, blood pressure, temperature, respiration, and PIR sensors. Videos or images of the patient may be taken using a camera for monitoring and assessment. The gathered data is wirelessly transferred to an embedded Raspberry Pi device, which analyses and uploads to a cloud server. The patient's data is stored on a cloud server, notifying medical personnel of unusual readings or movements. By giving healthcare providers fast access to reliable information to decide how best to treat patients, the proposed system may enhance patient outcomes. Additionally, a user-selectable interval for all process parameters is recorded online. This will be extremely helpful for further analyses and discussions of the patient's health.
