This document presents a wireless system for remotely monitoring a patient's blood oxygen saturation levels and pulse rate using IoT. Sensors including a pulse oximeter, temperature sensor, and IR sensor are used to monitor a patient's vital signs. The data is transmitted wirelessly via Bluetooth to a smartphone and to the cloud. If the oxygen level or other readings fall outside normal ranges, an alert is sent. The system was tested on real patients and performed satisfactorily in continuously transmitting health data and sending alerts during emergencies to help provide timely medical care from remote locations.
