Summary

The investigators aim to study the effect of liquid oxygen therapy (4l/min, nasal) )in Swiss residents with pulmonary vascular diseases (PVD) defined as pulmonary arterial hypertension (PAH) or chronic thromboembolic pulmonary hypertension (CTEPH).

Conditions

  • Pulmonary Vascular Disease
  • Chronic Thromboembolic Pulmonary Hypertension (CTEPH)
  • Pulmonary Arterial Hypertension (PAH)

Interventions

OTHER

6-minute walk distance (6MWD) test on ambient conditions

6-minute walk distance (6MWD) test will be performed on ambient air according to clinical standards

OTHER

6-minute walk distance (6MWD) test with supplemental oxygen (LOX)

6-minute walk test(6MWT) test will be performed according to clinical standards with supplemental liquid oxygen therapy (LOX, approximately 4l/min, nasal)
