We conducted a prospective, observational study to investigate the relationship between the
respiratory variation in aortic blood flow peak velocity (ΔVPeak) measured by …

Background The primary aim of the current study was to investigate the ability of respiratory
variations in descending aortic flow, measured with two‐dimensional echo at the …

Invasive monitoring is rarely used for children undergoing routine anaesthesia, whereas
usual non-invasive haemodynamic measurements such as heart rate and blood pressure …

Objective: To validate cardiac output measurements by ultrasound dilution technology
(COstatus monitor) against those obtained by a transit-time ultrasound technology with a …

Aortic peak systolic velocity variation (ΔV peakAo) is a reliable dynamic indicator of preload
in mechanically ventilated children. However, easily measurable alternative parameters like …

Background: The diameter of the aortic root is used as a parameter to calculate blood flow in
very preterm infants. There are considerable differences in diameter of the four anatomical …

In previous work, we postulated that mean aortic flow velocity (MAFV) might be a direct
measure of cardiac index. To investigate the assumptions inherent in this relation, we …

Background: It has recently been reported in critically ill patients that a linear relationship
exists between cardiac index (CI) measured with thermodilution and mean aortic blood flow …

Methods CO was determined at the end of diagnostic or interventional cardiac
catheterization for congenital heart defects. Standard ECG surface electrodes were attached …

This study was performed to evaluate the hemodynamic status of children admitted to the
intensive care unit, using suprasternal and transesophageal Doppler ultrasound, and to …
