Title: Mobile Phone Pulse Oximeter

There is global demand for low cost medical care diagnostics, and too often these life-saving tools are unavailable to low-income countries and remote areas of the world. One example of such a device is a pulse oximeter: a vital instrument that measures blood oxygen saturation. A modern medical grade pulse oximeter is often physically large and requires training and access to a mains power. All such points are contrary to operation in a remote low-income locale.

This project covers the design, fabrication, and testing of a testbed pulse oximeter that is targeted for use in the developing world. While developing areas may be lacking infrastructure, mobile phones are readily available. Mobile phones provide a source of power, computation, and access to information that was previously unavailable. By connecting through the headset jack, the testbed design utilizes the phone’s capabilities run a pulse oximeter. Data was acquired from the testbed and then analyzed with good results.

Global access to point-of-care medical devices can be significantly improved with further use of mobile computing. This will lead to reductions in cost, increased portability, improved patient compliance, and expanded distribution of medical knowledge.
