abstract：:Gastrointestinal (GI) blood flow, O2 transport, and O2 uptake were measured during recovery from severe hypoxemia in newborn piglets. Hypoxemia was induced by lowering the inspired O2 concentration to 0.05 for 15 min. This resulted in an 82% decrease in GI O2 uptake. Recovery measurements were obtained 5 and 65 min af...
