Ambulatory detection of sleep apnea using a non-contact biomotion sensor.

Ambulatory detection of sleep apnea using a non-contact biomotion sensor. J Sleep Res. 2019 Jun 30;:e12889 Authors: Crinion SJ, Tiron R, Lyon G, Zaffaroni A, Kilroy H, Doheny E, O'Hare E, Boyle P, Russell A, Traynor M, Kent BD, Ryan S, McNicholas WT Abstract The high prevalence of obstructive sleep apnea has led to increasing interest in ambulatory diagnosis. The SleepMinder™ (SM) is a novel non-contact device that employs radiofrequency wave technology to assess the breathing pattern, and thereby estimate obstructive sleep apnea severity. We assessed the performance of SleepMinder™ in the home diagnosis of obstructive sleep apnea. One-hundred and twenty-two subjects were prospectively recruited in two protocols, one from an unselected sleep clinic cohort (n = 67, mean age 51 years) and a second from a hypertension clinic cohort (n = 55, mean age 58 years). All underwent 7 consecutive nights of home monitoring (SMHOME ) with the SleepMinder™ as well as inpatient-attended polysomnography in the sleep clinic cohort or cardiorespiratory polygraphy in the hypertension clinic cohort with simultaneous SleepMinder™ recordings (SMLAB ). In the sleep clinic cohort, median SMHOME apnea-hypopnea index correlated significantly with polysomnography apnea-hypopnea index (r = .68; p < .001), and in the hypertension clinic cohort with polygraphy apnea-hypopnea index (r = .7; p < .001). The median SMHOME performance agains...
