Key result
Contactless video monitoring of respiratory and heart rates in non-acuity settings showed high correlation with standard methods (R^2 0.88-0.91) and low mean absolute errors (0.84 and 2.15 bpm).
Why the study?
Does a contactless video monitoring system accurately measure respiratory rate and heart rate compared to standard monitors in non-acuity hospital settings?
Population
158 subjects in a low-acuity setup (general ward and dialysis unit) at a tertiary care hospital in India
Comparison
Contactless monitoring system using a video… vs Alice NightOne and manual counts

Does a contactless video monitoring system accurately measure respiratory rate and heart rate compared to standard monitors in non-acuity hospital settings?
Contactless video monitoring provides an accurate and unobtrusive method for measuring respiratory and heart rates in non-acuity hospital settings.
Varma et al. (2022) conducted a cross-sectional in Low-acuity hospitalised patients (n=158). Contactless video monitoring vs. Alice NightOne and manual counts was evaluated on Vital parameters (RR and HR). Contactless video monitoring of respiratory and heart rates in non-acuity settings showed high correlation with standard methods (R^2 0.88-0.91) and low mean absolute errors (0.84 and 2.15 bpm).
