Clinical Study
Volumetric and End-Tidal Capnography for the Detection of Cardiac Output Changes in Mechanically Ventilated Patients Early after Open Heart Surgery
Figure 4
Scatterplot EtCO2. Correlation between mean relative changes in CO and EtCO2 from BL to RVP and PLR, respectively. Least significant changes for CO and EtCO2 are indicated with shadows. CO = cardiac output; EtCO2 = end-tidal carbon dioxide; VtCO2 = exhaled carbon dioxide per tidal volume; BL = baseline; RVP = right ventricular pacing; PLR = passive leg raise; ρ = Spearman’s rho with confidence intervals.
