In this project, the investigators aim to assess changes of physiological parameters obtained non-invasively through PPG and accelerometry signals between before and during LTOT (long-term oxygen therapy) and investigate if those changes are different in patients with worsening frailty and/or improving quality of life.
For this, they will record optical (PPG) and accelerometry data via a datalogger on 40 patients undergoing LTOT and assess the PPG-derived physiological signals.
