Figure 1

Bland–Altman plots of the relationship (right panels) and agreement (left panels) between the PPG-based device and invasive measures. Measurements obtained by the PPG-based device, arterial line (AL) or Swan-Ganz (SG) include heart rate [HR; (a,b)], systolic blood pressure [SBP; (c,d)], diastolic blood pressure [SBP; (e,f)], and cardiac output [CO; (g,h)]. In the left panels, the solid line is the best fit linear regression and the dash line is the line of identity. In the right panels, the solid horizontal line represents the mean difference between the two measurements and the dash horizontal lines represent the limits of agreement. Blue symbols: pre bleeding phase; red symbols: bleeding phase; green symbols: post bleeding phase.
