WitrynaTissue oxygenation may be impaired either by a low arterial oxygen saturation, as in cyanotic congenital heart disease, or by a reduced blood flow, as occurs with myocardial failure or with obstruction to the left heart (aortic atresia). Anaerobic metabolism results in the accumulation of lactic acid in the tissues. WitrynaA growing body of evidence suggest that tissue oxygen extraction may be impaired in adult respiratory distress syndrome (ARDS) and sepsis. In these syndromes the minimum oxygen delivery needed to maintain a normal oxygen uptake appears to be increased, as tissues become hypoxic despite high levels of delivery. However, controversy …
