Published in 2025 at "Scientific Reports"

DOI: 10.1038/s41598-025-02270-x

Abstract: Rapid respiratory rate (RR) changes in older adults may indicate serious illness. Therefore, accurately estimating RR for cardiorespiratory fitness is essential. However, machine learning algorithm-related errors are unsuitable for medical decision-making processes because some data… read more here.
