Cardiac Output Monitoring in Children, Adolescents and Adults Based on Pulse Contour Analysis: Comparison with Echocardiography-Derived Data and Identification of Factors Associated with Their Differences.

CO(PCA) had systematic (< 0.17 L/min) and percent (≤ 30%) errors, which allow us to postulate that its use allows reaching levels comparable to those of echocardiography. Differences in CO-data between methods were associated with arterial and cardiac properties.
