Correction factor introducing method for use during transpulmonary thermodilution with femoral during injection of cold bolus into vena jugularis and vena subclavia, involves finding thermodilution curve from temperature changes in blood

摘要

The method involves providing a central venous catheter for injecting cold bolus into vena jugularis and vena subclavia over inferior canal vein. A thermodilution sensor is arranged in arteria femoralis for detecting temperature changes of blood. A thermodilution curve is determined from the temperature changes in the blood over a time period based on hemodynamic parameter e.g. cardiac output, intrathoracic blood volume, and global end-diastolic volume.
