Brief Summary:
The purpose of this study is to determine whether the endotracheal cardiac output monitor (ECOM) is accurate and predictive in liver failure patients with hyperdynamic circulatory changes.

Group/Cohort Intervention/treatment
OLT patients intubated with ECOM ETT
Patients undergoing liver transplantation and intubated with ECOM endotracheal tube (ETT).
Device: ECOM ETT
Intubation with ECOM endotracheal tube (ETT)

Primary Outcome Measures :
  1. endotracheal cardiac output monitor (ECOM), a non-invasive cardiac output monitor, is accurate and predictive [ Time Frame: Less than 24 hours ]
    Pulmonary artery catheters are a standard of care for intraoperative hemodynamic assessment during liver transplantation. We propose to compare hemodynamic parameters obtained from PA catheters and ECOM. Use the endotracheal cardiac output monitor (ECOM) to evaluate multiple hemodynamic parameters (invasive blood pressure from the indwelling arterial catheter, noninvasive cardiac output via ECOM), and compare these to the parameters obtained from PA catheter.
