Cardiac output at skin level: PPC vs. Fick method

Comparison of cardiac output by Fick formula vs. thermodilution, following vasodilator challenge in pulmonary hypertension

Introduction: Cardiac output and index, measured during right heart catheterization are used to define vasoreactivity and predict mortality. The Fick and thermodilution methods are routinely used, but have not been compared following vasoreactivity. Methods: We retrospectively reviewed the RHC data of 50 patients; that met inclusion criteria, of a right heart catheterization with inhaled nitric...

Cardiac output during exercise by the open circuit acetylene washin method: comparison with direct Fick.

An open-circuit (OpCirc) acetylene uptake cardiac output (QT) method was modified for use during exercise. Two computational techniques were used. OpCirc1 was based on the integrated uptake vs. end-tidal change in acetylene, and OpCirc2 was based on an iterative finite difference modeling method. Six subjects [28-44 yr, peak oxygen consumption (VO(2)) = 120% predicted] performed cycle ergometry...

A continuous cardiac output recorder employing the Fick principle.

Comparison of cardiac output determined by bioimpedance, thermodilution, and the Fick method.

BACKGROUND Cardiac output can be determined by using a variety of methods. OBJECTIVES To determine the precision and bias between 3 methods for determining cardiac output: bioimpedance, thermodilution, and the Fick method. METHODS Cardiac output was determined by using bioimpedance via neck and thorax patches and thermodilution via pulmonary artery catheter in 46 patients in the intensive c...

Cardiac output measurement using a modified carbon dioxide Fick method: comparison analysis with pulmonary artery catheter method and pulse induced contour cardiac output method.

OBJECTIVES In the present study, cardiac output in mechanically ventilated patients were determined using three methods including modified CO2-Fick (mCO2F), pulmonary artery catheter (PAC), and pulse induced contour cardiac output (PiCCO) methods and the results were compared to assess the effectiveness of mCO2F method in measuring the cardiac output. METHOD Mechanically ventilated and hemody...
