摘要: Measurement of cardiac output using thermodilution technique in mechanically ventilated patients is associated with significant morbidity. The goal the present study was to assess validity measurement transesophageal Doppler critically ill patients. Forty-six from three different intensive care units underwent 136 paired measurements (COTH) and (COTED). In addition, simultaneous suprasternal indirect calorimetry (Fick principle) were used measure 26 one center. A good correlation found between COTH COTED (r = 0.95), a small systematic underestimation (bias 0.24 L/min) Doppler. limits agreement + 2 L/min − 1.5 L/min. Variations two consecutive measures either or techniques similar direction magnitude (b...
