Noninvasive Monitoring of Cardiac Output in Critically Ill Patients Using Transesophageal Doppler

摘要

Measuement of cardiac output using thermodilution technique in mechanically ventilated patients is associated with significant morbidity. The goal of the present study was to assess the validity of car- diac output measurement using transesophageal Doppler in critically ill patients. Forty-six patients from three different intensive care units underwent 136 paired cardiac output measurements using thermodilution(CO_TH) and transesophageal Doppler(CO_TED). In addition, simultaneous suprasternal Doppler and indirect calorimetry(fick principle) were used to measure cardiac output in 26 patients From one center.
