Fig. 3

Original registration in an anesthetized spontaneously breathing dog. After 2 heart cycles, recording speed was reduced and tracings of COTransonic and pulmonary arterial pressure (PAP) were switched to mean values. At the end of each intervention, blood volumes were determined in duplicate. During hypoxia, PAP increased markedly, whereas pulmonary capillary wedge pressure (PCWP), and pulmonary blood volume (PBV) remained unchanged. *: PCWP was determined intermittently at three moments. **: a zero-adjustment was performed at three moments
