Answer

Long-term oxygen supplementation therapy should be used for hypoxemic patients with PVOD to keep their oxyhemoglobin saturation at greater than 90% at all times. This may result in symptomatic and subjective improvement. No direct good-quality evidence exists for speculation about the magnitude of benefit in terms of survival or exercise capacity in patients with PVOD.
