Clinical validation of the Bedbugg in detection of obstructive sleep apnea.

Abstract

To validate the accuracy of the Bedbugg, a new home monitoring device for diagnosis of obstructive sleep apnea. Simultaneous sleep monitoring was performed by formal polysomnography and by Bedbugg. Monitoring was performed in a university sleep center in 42 subjects who had previously been scheduled for polysomnography. The correlation for the apnea-hypopnea index (AHI) between polysomnography and Bedbugg was r = 0.96. The sensitivity of Bedbugg for detecting an AHI > 15 was 85.7%. The specificity of Bedbugg for detecting an AHI < 15 was 95.2%. The Bedbugg device provides an accurate assessment of the apnea-hypopnea index. Accurate home monitoring for sleep apnea may provide access to care for a higher proportion of undiagnosed sleep apnea patients.
