Telemonitoring of daily activities compared to the six-minute walk test further completes the puzzle of oximetry-guided interventions

Abstract Pulmonary rehabilitation is based on a thorough patient assessment, including peripheral oxygen saturation (SpO2) and heart rate (HR) at rest and on exertion. To understand whether exercise-field tests identify patients who desaturate (SpO2 < 90%) during physical activities, this study c...
