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

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.

3-[(E)-1-(Benzyl-oxyimino)eth-yl]-2-oxo-2H-chromen-7-yl acetate.

The title compound, C(20)H(17)NO(5), was prepared by the reaction of 3-acetyl-2-oxo-2H-chromen-7-yl acetate with benzyl-oxy-amine. The mol-ecule adopts an E configuration with respect to the C=N double bond. The dihedral angles between the coumarin ring system, the phenyl ring and the C=N-O-C plane of the oxime unit are 35.
