Using standard medical sensors connected directly through the universal audio port of virtually any mobile device, the proprietary interface, called the Vital Signs DSP (Digital Signal Processor), provides precise monitoring of blood oxygen levels, blood pressure and body temperature which are displayed on the mobile device’s monitor.
The technology requires no external signal processors, microcontrollers, power sources or displays. Users just download a proprietary app that allows their mobile device to drive a low-cost standard medical sensor. Dr. Ansermino, Associate Professor in the Department of Anesthesiology, Pharmacology and Therapeutics, worked with Guy Dumont, Professor of Electrical and Computer Engineering, and their team, Electrical & Computer Engineering in Medicine (ECEM), to develop Vital Signs DSP.
