Non-invasive cardiac output measurement by electrical cardiometry and M-mode echocardiography in the neonate: a prospective observational study of 136 neonatal infants.

ABSTRACT:

Background

Electrical cardiometry (EC) is a continuous, non-invasive method for measuring cardiac output (CO). This study investigates the correlation and consistency of CO values in newborns obtained by using EC and M-mode echocardiography (Teichholz formula).

Methods

In this prospective observational study, simultaneous measurement of CO was implemented with EC (COec) and M-mode echocardiography (COm) in neonates. The absolute values of CO measured by the two methods were converted to Z-scores. Following that, Pears's correlation analyses and the Bland-Altman index were employed to analyze the correlation and consistency of COec Z-scores and COm Z-scores.

Results

A total of 136 neonates (93 preterm infants) were enrolled in this study, and EC and M-mode echocardiogr
