Home spirometry is gaining acceptance in the medical community because of its ability to detect pulmonary exacerbations and improve outcomes of chronic lung ailments. However, cost and usability are significant barriers to its widespread adoption. To this end, we present SpiroSmart, a low-cost mobile phone application that performs spirometry sensing using the built-in microphone. We evaluated SpiroSmart on 52 subjects, showing that the mean error when compared to a clinical spirometer is 5.1% for common measures of lung function. Finally, we showed that pulmonologists can use SpiroSmart to effectively diagnose lung ailments. Now we are in process of developing a call-in service as well. Users would no longer need a smartphone to check their lung functions. They would be able to do it directly from a feature-phone over the voice channel of the network.
Mayank Goel is a PhD student in Computer Science and Engineering at University of Washington, where he works with Prof. Gaetano Borriello and Prof. Shwetak Patel. His research involves leveraging smartphones and sensing infrastructure for ubiquitous computing applications. He is interested in developing low-cost sensing solutions for healthcare in low resource environments. He received his M.S. in Computer Science from Georgia Institute of Technology in 2009, where he specialized in ubiquitous computing.
