Estimates of the first three principal components (PC1 to PC3) for each individual ventilatory condition. A multi-dimensional k-means clustering algorithm was applied to these estimates to identify the PaO2 waveform cluster. The resulting clusters are denoted by colours and individual animals identified with shapes. An interactive 3D version of this figure is provided in Additional file 5: Fig. S5
