Fig. 4From: Intra-tidal PaO2 oscillations associated with mechanical ventilation: a pilot study to identify discrete morphologies in a porcine modelAllocation of PaO2 oscillations to each of the five identified clusters. Thin lines show all individual waveforms colour-coded by PaO2 oscillation cluster membership. Thick lines denote per-cluster mean, and light grey background inspirationBack to article page
