Authors' conclusions Based on low quality of evidence, LTOT (~ 15 hours/day) decreases all-cause mortality in patients with COPD who have severe hypoxemia (PaO2 ~ 50 mm Hg) and heart failure. The effect for all-cause mortality had borderline statistical significance when the control group was no LTOT: one study. Based on low quality of evidence, there is no beneficial effect of LTOT on all-caus...

Hepatopulmonary syndrome (HPS) is characterized by pulmonary vasodilation and subsequent hypoxemia in the setting of hepatic dysfunction. There is currently no pharmacologic intervention that has been shown to significantly affect outcomes and liver transplantation remains the mainstay of therapy. Unfortunately, patients undergoing liver transplantation are at high risk of significant hypoxemia...

In 2009, during the influenza A (H1N1) epidemic, there were many reported cases of pulmonary infection with severe hypoxemia that was refractory to the ventilatory strategies and rescue therapies commonly used to treat patients with severe acute respiratory distress syndrome. Many of those cases were treated with extracorporeal membrane oxygenation (ECMO), which renewed international interest i...
