Key result
Contactless monitoring technologies provided acceptable accuracy for estimating heart rate (mean absolute error < 2.2 bpm) and breathing rate (mean absolute error ≤ 1.6 cpm) compared to polysomnography in older adults.
Why the study?
Contactless technologies embedded into the bedroom environment could enable seamless, longitudinal monitoring of vital signs during sleep in older adults, but require evaluation against gold standard measures in relevant populations.

Do contactless sleep monitoring technologies accurately measure heart rate and breathing rate compared to polysomnography in older adults?
Contactless under-mattress and bedside radar technologies provide accurate heart rate and breathing rate monitoring during sleep in older adults compared to gold-standard polysomnography.
Ravindran et al. (2023) conducted an observational in Aging and Sleep Apnea (n=35). Contactless monitoring technologies (Withings sleep analyser, Emfit QS, Somnofy) vs. Polysomnography (PSG) was evaluated on Accuracy of heart rate and breathing rate measurements (Mean Absolute Error and Mean Absolute Percentage Error). Contactless monitoring technologies provided acceptable accuracy for estimating heart rate (mean absolute error < 2.2 bpm) and breathing rate (mean absolute error ≤ 1.6 cpm) compared to polysomnography in older adults.
