AB  - Sleep-disordered breathing (SDB), cardiac and respiratory disease are highly prevalent in the elderly population, and often not diagnosed. A contactless mattress-based monitor (Sonomat) records breath and heart sounds, simultaneously detecting breathing and body movements. This enables the identification of adventitious sounds and the quantification of sleep and sleep disturbance (Norman, M.B. et al. Sleep 2014; 37(9):1477-1487).Aim: To assess the capability of contactless monitoring in elderly people for SDB, respiratory and cardiac disease.Methods: Eight volunteers (3 male, age = 84 ± 4 years) were from an in-home telemonitoring project. The participants were required to turn the device on/off at sleep-time and wake-time respectively. Data was stored in the device for offline analysis.Results: All subjects performed successful Sonomat recordings. View this table:Range of sleep disordered breathing variablesView this table:Pathological sounds identified during sleepPathological sounds were present in all subjects. Crackles typically occurred at the same time as central apneas and hypopneas.Conclusion: Nocturnal contactless monitoring is achievable with elderly people at home. Signs of nocturnal respiratory and cardiac co-morbidities were identified in all. A high prevalence of SDB and cardiorespiratory comorbidities in elderly has been confirmed.
