Abstract

We present the hardware design of an FPGA-based portable device for home screening of sleep apnea syndromes. The device is simple to use, inexpensive, and uses only three signals, namely the nasal air flow and the thorax and abdomen effort signals. The device hardware stores data of overnight sleep on a Secure Digital card. At the clinic, the sleep specialist reads in the stored data and uses an algorithm for the detection and classification of sleep apnea. The device is fairly low-cost and may help spread the ability to diagnose more cases of sleep apnea. Most sleep apnea cases currently go undiagnosed because of cost and practicality limitations of overnight polysomnography at sleep labs.
