Oxygen therapy can enhance the quality of life of patients with pulmonary arterial hypertension or PAH who experience hypoxemia or low oxygen levels. This treatment helps prevent potential organ damage.

By increasing and sustaining blood oxygen levels, oxygen therapy reduces fatigue, improves breathing, and boosts concentration.

Furthermore, oxygen acts as a pulmonary vasodilator, effectively lowering the elevated pressure in the pulmonary arteries.

In PAH therapy, a critical target is the alveolar endothelium.

While current guidelines recommend supplemental oxygen therapy only for severe hypoxemia, recent research suggests potential benefits for all PAH patients.

This therapy can typically be administered at home through various means, including nasal cannulas, face masks, oxygen concentrators, or portable oxygen cylinders, either in gaseous or liquid form.

Challenges associated with oxygen therapy in PAH encompass cost considerations, practical issues, and compliance with the treatment.
