Does the NAPS system accurately detect heart rate and breathing rate compared to standard measures in healthy subjects?
The NAPS system demonstrates preliminary accuracy for passive, noninvasive monitoring of heart rate and breathing rate during sleep.
Mack et al. (2008) conducted an observational in Healthy (n=40). Noninvasive analysis of physiological signals (NAPS) system vs. ECG, pulse oximetry, and respiratory inductance plethysmography (RIP) was evaluated on Heart rate and breathing rate accuracy. The NAPS system detected heart rate to within 2.72 beats per minute of ECG and breathing rate to within 2.10 breaths per minute of RIP during overnight sleep studies.
