Does a non-intrusive pneumatic sensor accurately measure cardiorespiratory metrics during sleep compared to polysomnography in sleep laboratory participants?
A non-intrusive pneumatic sensor can accurately estimate overnight cardiorespiratory metrics including heart rate and respiratory rate compared to standard polysomnography.
Effect estimate: Bias -0.8 bpm (heart rate) (95% CI -4.3 to 2.7 (95% LOA))
Abstract We show that a non-intrusive pneumatic sensor can be used to measure respiratory rate, heart rate, and their variability during sleep. The pneumatic sensor was included in a polysomnography (PSG) study involving 42 participants in a sleep laboratory. The agreement between the pneumatic sensor and the PSG for respiratory rate, heart rate, and their variability was quantified by Bland-Altman analysis. The respiratory rate has a mean value of 15.4 breaths per minute for a bias of −0.06 and 95% limits of agreement (LOA) of −0.6; 0.5 breath per minute. The respiratory rate variability root mean square of successive differences (RMSSD) has a mean value of 459.51 ms, a bias of 9.2 and a 95% LOA of −43.5; 61.9 ms. The heart rate has a mean value of 60.6 beats per minute for a bias of −0.8 and a 95% LOA of −4.3; 2.7 beat per minute. The heart rate variability RMSSD has a mean value of 44.1 ms, a bias of 14.7 and a 95% LOA of −19; 48.4 ms. These results show that a non-intrusive pneumatic sensor can accurately estimate cardiorespiratory metrics overnight.
Yang et al. (Thu,) conducted a observational in Sleep (n=42). Non-intrusive pneumatic sensor vs. Polysomnography (PSG) was evaluated on Agreement between pneumatic sensor and PSG for respiratory rate, heart rate, and their variability (Bias -0.8 bpm (heart rate), 95% CI -4.3 to 2.7 (95% LOA)). A non-intrusive pneumatic sensor accurately estimated overnight cardiorespiratory metrics compared to polysomnography, demonstrating a heart rate bias of -0.8 bpm (95% LOA -4.3 to 2.7).
