WitrynaWhen the arterial oxygen content (CaO 2) and/or CO becomes impaired, DO 2 decreases, which is often accompanied by a parallel decrease in VO 2. The most frequently occurring scenarios are represented in Figure 1. In the early phase of decreasing DO 2, the circulation can compensate to some extent, and VO 2 remains … 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.
