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

OBJECTIVE To validate the accuracy of the Bedbugg, a new home monitoring device for diagnosis of obstructive sleep apnea. STUDY DESIGN AND SETTING 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. RESULTS 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%. CONCLUSION The Bedbugg device provides an accurate assessment of the apnea-hypopnea index. SIGNIFICANCE Accurate home monitoring for sleep apnea may provide access to care for a higher proportion of undiagnosed sleep apnea patients.
