Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Background:

Impedance cardiography (ICG) is a noninvasive method for continuous left cardiac output monitoring based on measurement of thoracic electrical bioimpedance. The objective of this study is to validate an ICG device by investigating the agreement in cardiac output (CO; left ventricular output x heart rate) measurements performed by ICG and echocardiography. The ICG device (PhysioFlow) has a new filter technology reducing signal noise and enabling measurements in patients who are moving freely.

Material and Methods

* Design: Prospective observational study.
* Inclusion: 30 healthy term infants between 24 and 48 hours of age, after parental consent
* Methods: Continuous measurement with ICG over a 30 min period and point of care echocardiography
* Primary outcome: Agreement (bis and precision) between measurement of CO with ICG and echocardiography.
* Secondary outcomes: Agreement between other echocardiographic indices of myocardial function and ICG parameters (early diastolic filling ratio, cardiac index, ventricular ejection time and left cardiac work index).
* Statistics: Agreement between ICG and echocardiography data will be evaluated using Bland-Altman statistics, including the calculation of mean bias (average difference between measurements) with corresponding standard deviation and lower and upper limits of agreements (95% confidence interval).
