简要总结
The purpose of this study is to test a new way to measure the oxygen level in the mixed venous blood system (the system that carries blood collected from all over the body to the heart), which is a very important monitoring tool for the overall oxygen delivery to all our tissues. This new way measures the oxygen level in the mixed venous blood from outside the body, instead of measuring from the inside through a catheter (a thin, flexible plastic tube) that is placed by breaking the skin.

结局指标
主要结局
Determining the Accuracy of Mixed Venous Oxygen Saturation Obtained With a Novel Mathematical Equation Using Arterial Oxygen Saturations and Various Local Tissue Oxygen Saturations.
时间窗: 6 months
Four sensors of the 'Cerebral/Somatic Tissue Oximeter' device will be placed on subject's both sides of the forehead, palm and calf area. Simultaneously, blood samples will be drawn from the pulmonary artery catheter and arterial line for blood gas analyses. The values obtained from the device measurements will be used in a new equation to calculate the mixed venous oxygen saturation. The calculated value will be compared to the real value from the blood gas analysis for accuracy.
