Scientists have developed a new wearable monitor to detect obstructive sleep apnoea, which may improve sleep apnoea testing at home.
The adhesive patch weighs less than one ounce and records nasal pressure, blood oxygen saturation, pulse rate, respiratory effort, sleep time and body position.
In a trial, simultaneous polysomnography and patch recordings from 174 subjects were analysed. The total rate of clinical agreement between the patch and standard in-lab polysomnography was 87.4 per cent, with a 95 per cent confidence interval of 81.4 per cent to 91.9 per cent.
“Our study provided clinical validation of a new wearable device for diagnosing sleep apnoea,” said principal investigator Maria Merchant, CEO of Somnarus Inc. “It was most surprising to us how well this inexpensive miniature device performed in comparison with in-lab sleep studies.”
The study results will now be used to apply for approval from the U.S. Food and Drug Administration for the SomnaPatch.
The findings will be presented at the 31st Annual Meeting of the Associated Professional Sleep Societies LLC (APSS) in Boston today (Wednesday, June 07). It is expected that the Sleep 2017 conference will be attended by more than 5,000 delegates.
