Overview
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.
Eligibility
Inclusion Criteria:
- Age ≥ 18-year-old, and
- Chronic respiratory disease including a) chronic obstructive pulmonary disease, b) interstitial lung disease, c) pulmonary hypertension, d) bronchiectasis, and
- Prescribed new LTOT due to a chronic respiratory disease with resting and/or exertional hypoxemia, and
- Able to speak/read/understand German or French, and
- Willing and able to understand and provide signed informed consent
Exclusion Criteria:
- Pregnant or lactating women, or
- Inability to follow the procedures/instructions of the study (e.g. due to language, psychological disorders, dementia, etc.), or
