  Purpose
The primary objective of this study is to obtain the TPTD, GEDV and EVLW measurements from existing indwelling femoral arterial Volume View™ catheter and central venous catheters.

Condition
Cardiac Output and Preload Assessment Lung Water Assessment

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Clinical Evaluation of a New Transpulmonary Thermodilution Method to Assess TPTD, GEDV and EVLW

Further study details as provided by Edwards Lifesciences:

Primary Outcome Measures:
  • TPTD, GEDV and EVLW measurements to evaluate the precision and accuracy of a novel algorithm in comparison to the widely accepted TPTD method [ Time Frame: Up to 72 hours of femoral arterial catheter dwell time. ]
    This is not an outcome study. This is an observational Study to obtain TPTD, GEDV and EVLW data to evaluate the precision and accuracy of a novel algorithm in comparison to the widely accepted TPTD method using an approach defined by Bland-Altman.

Groups/Cohorts
EV1000 Observational Group
Patient must have an indwelling femoral arterial catheter and central venous catheter considered necessary for routine clinical monitoring; Patient, or legal guardian, will give consent prior to study enrollment and data capture; Patient must be at least 18 years old; Patient height and weight are available prior to study.

Detailed Description:

Transpulmonary thermodilution has been proposed to measure transpulmonary thermodilution cardiac output (TPTD), preload (GEDV, global end diastolic volume) and to quantify pulmonary edema (EVLW, extravascular lung water). The method currently available on the market is based on the estimation of time characteristics of the curve (mean transit time and down slope time).

The purpose of this study is to evaluate a new transpulmonary thermodilution method to assess the TPTD, EVLW and GEDV in patients requiring cardiac preload and lung water assessment. Up to one hundred (100) patients will be enrolled at four (4) study sites, (up to 25 subjects at each site). Hôpitaux Universitaires de Genève, Universität Bonn, Stadtspital Triemli Zürich, and Universitätsklinikum Aachen will participate in the study.

This is a prospective, observational data collection study.
