Clinical Study

Volumetric and End-Tidal Capnography for the Detection of Cardiac Output Changes in Mechanically Ventilated Patients Early after Open Heart Surgery

Figure 5

Correlation between mean relative changes in CO and VtCO2 from BL to RVP and PLR, respectively. Least significant changes for CO and VtCO2 are indicated with shadows. Dots are for RVP; circles are for PLR. 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.
