Why the study?
Respiratory rate is a valuable vital sign for remote long-term monitoring, but implementation is challenging and contactless home-use devices aim to address this need.
Does the Sleepiz One+ contactless respiration monitor accurately measure instantaneous respiratory rate and its summary statistics compared to a thoracic effort belt in patients with sleep-related breathing disorders?

Does the Sleepiz One+ contactless respiration monitor accurately measure instantaneous respiratory rate and its summary statistics compared to a thoracic effort belt in patients with sleep-related breathing disorders?
Mean Difference: 0.48 (95% CI -0.88–1.61)
The Sleepiz One+ contactless respiration monitor accurately estimates instantaneous respiratory rate and summary statistics during sleep compared to standard thoracic effort belts, demonstrating potential for remote long-term patient monitoring.
Bujan et al. (2023) conducted an observational in Sleep-related breathing disorders and chronic cardiopulmonary conditions (n=158). Sleepiz One+ contactless respiration monitor vs. Thoracic respiratory effort belt (TREB) was evaluated on Agreement of instantaneous respiratory rate (mean absolute error) (MAE 0.48 Brpm, 95% CI -0.88 to 1.61). The Sleepiz One+ contactless respiration monitor demonstrated excellent agreement with the thoracic effort belt during overnight monitoring, achieving 99.5% accuracy within 3 breaths per minute and a mean absolute error of 0.48 Brpm.
