TABLE 1.

Statistical analysis of algorithm determined cardiac output (ih + ip) and systemic vasculature resistance (R) compared against the thermodilution measured cardiac output (TCO) and systemic vasculature resistance (SVR).

Cardiac output (L/min) Systemic vascular resistance (dynes-s/cm5)
Reference mean (low-high) 6.0 (3–10.6) 1054 (501–1897)
Bias (mean) − 0.11 − 62
Precision (standard deviation) 0.89 161
Limits of agreement (95% confidence interval) 1.75 315
Percentage error 29.1% 29.9%
Correlation plot (slope) 1.08 1.04
Correlation plot (offset) − 0.39 18.8
Correlation coefficient (r) 0.82 0.86
