Abstract

We present a project that focused on creating a wearable medical device that uses pho- toplethysmography and pulse oximetry technology. The pulse oximeter sensor holder was designed to be mounted on the chest using adhesive tape and a threaded holder that the cover turns into to increase pressure on the sensor. Our holder can apply a pressure range of 0-51 mmHg. The range for greatest PPG amplitudes from the chest is 10-30 mmHg. The reflectance type pulse oximeter housed in the holder was able to read pulse rate to within approximately ±1.35 BPM compared to the EKG heart rate signal. Industry standards for finger pulse oximeters read pulse rate with ±3 BPM accuracy. The device was not tested for oxygen saturation due to time constraints and IRB approved testing.
