Figure 2

Dendrogram describing the constituents of mean arterial pressure and oxygen delivery in the context of suspected decompensation. For each key abnormality, physiologic variables are indicated in black, along with the main corresponding medical diagnoses indicated in blue. For each, key differentiating findings of laboratory or physiologic monitor data are presented in red. Abbreviations: VO2, oxygen uptake; DO2, oxygen delivery; CO, cardiac output; MAP, mean arterial pressure; SVR, systemic vascular resistance; CVP, central venous pressure; PaOP, pulmonary artery occlusion (wedge) pressure; PAP, pulmonary artery pressure; PTX, pneumothorax.
