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.

Condition Intervention
Liver Transplantation Device: ECOM ETT

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: Noninvasive ECOM Monitoring of Hemodynamic Parameters During Liver Transplantation

Primary Outcome Measures:
  • 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.
