|Abstract:||Obstructive Sleep Apnoea (OSA) is an extremely common disorder creating a significant burden on Respiratory services. Sleep studies where among top 5 procedures for elective hospitalisation in 2016. Since the emergence of the SARS-CoV2 pandemic, there has been a shift towards home Limited Sleep Studies (LSS) which are widely accepted for OSA diagnosis. They are, however resource intensive and can be challenging for patients. |
WatchPAT is a wrist-based device which utilised peripheral arterial signal, heart rate, oximetry, actinography, body position, snoring and chest motion to provide AHI, RDI, ODI & Sleep Time for OSA diagnosis. WatchPAT is clinically validated, with an 89% correlation with PSG. To date, it has not been compared to Limited Sleep Studies.
We preformed 38 simultaneous home Limited Sleep Studies and WatchPAT analysis (13 female, age 50years ±12years) recruited from our Sleep Clinic. Thirty six WatchPAT studies were diagnostic and 38 LSS. Mean AHI by LSS was 21 ± 23 events per hour, with 6 normal studies, 7 with mild, 12 moderate and 15 with severe OSA. Correlation between LSS and WatchPAT AHI, RDI and ODI is 0.81, 0.80 and 0.74, p<0.001 respectively.
We found the WatchPAT device is accurate for home diagnosis of OSA in a Sleep Clinic population.
