The thermodilution technique with a pulmonary artery catheter has been the standard in adult patients for cardiac output measurement. However, using pulmonary artery catheter remains a major clinical problem in children due to technical and size constraints.
COstatus measures changes in blood ultrasound velocity in an extracorporeal AV loop caused by body-temperature isotonic saline injected into the central vein and calculates cardiac output derived from a dilution curve.

- Measurement of cardiac output by a new ultrasound dilution method in mechanically ventilated children after pediatric cardiac surgery. [ Time Frame: Measurements are made during a patient's stay with insitu catheters. The expected average stay is 3-4 days. ]To compare cardiac outputs measured with this new ultrasound dilution method with flowmetry (perivascular probe) using ultrasound transit time measured directly on the aorta in children < 15 kg of weight. Also to assess reliability of COstatus measurements in pediatric patients.
