Clinical validation of the Bedbugg in detection of obstructive sleep apnea
1UCSF Sleep Disorders Center, UCSF, San Francisco, California 94115, USA. dclaman@itsa.ucsf.edu
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.
