Why the study?
Pulmonary vasodilators, including oxygen, have not shown consistent beneficial effects in pulmonary hypertension due to valvular heart disease.
Does acute administration of 100% oxygen improve pulmonary hemodynamics in patients with pulmonary hypertension due to valvular heart disease?
Does acute administration of 100% oxygen improve pulmonary hemodynamics in patients with pulmonary hypertension due to valvular heart disease?
Acute administration of 100% oxygen significantly reduces mean pulmonary artery pressure and pulmonary vascular resistance in patients with pulmonary hypertension due to valvular heart disease.
No takes yet. Share an insight, caveat, or question.
Hyperoxia may reduce MPAP and PVR in PH-VHD; leaves open whether acute oxygen testing should inform perioperative or procedural decisions.
