Apnea MedAssist II: A smart phone based system for sleep apnea assessment

We have developed a real-time sleep apnea monitoring system called “Apnea MedAssist II”. This has three independent sensors: ECG, SpO2 and Breath sensor. These sensors are connected to a smartphone via Bluetooth. The signal processing of the sensor signals and automated classification of a sleep epoch as an apnea event or a non-apnea event are done in a smart phone. The soft ware for signal processing and automated classification can be imported to an Android OS based smart phones as an `app' that we have developed. The system has accuracy well over 97% when tested on Physionet database. The system is being readied for limited patient trial.
