Smart Health Monitoring System in Intensive Care Unit using Bluetooth Low Energy and Message Queuing Telemetry Transport Protocol

Smart healthcare monitoring is very essential for people who are in the Intensive Care Unit (ICU) in hospitals which provides continuous monitoring of health parameters, which cannot be afforded outside the hospitals. Because of the ever-increasing population of the world, smart health care has become increasingly crucial. The traditional patient-doctor consultation has lost its usefulness. The effective way of monitoring the patient’s health within ICU has great potential to introduce Bluetooth Low Energy (BLE) and Message Queuing Telemetry Transport (MQTT) protocol. The patient’s survival can be improved by the daily care of parameters such as heart rate, Hemodynamic, skin temperature, capillary refill, mental status, etc., which can be wirelessly monitored in smart way using BLE and MQTT. In addition, the Short Message Peer to Peer (SMPP) protocol could also be used for alerting the doctors if the sensor values go to a critical level as per the threshold value. It uses BLE and MQTT in monitoring the health of an ICU patient and also it will compare the ZigBee technology, which is already used in monitoring health parameters in following criteria low power, performance, cost, availability etc., with the proposed method. ZigBee will not support android version which is very important to access the smart phones. But the proposed method can support android version with low power consumption.
