简要总结
The purpose of this study is to determine whether analysis of near infrared absorbance signals that occur at different frequencies might provide information about the difference in oxygen saturation between arterial and venous blood.

研究组 & 干预措施
All
All subjects will undergo spontaneous ventilation through an impedance threshold device and ScvO2 will be recorded before and after
干预措施: Use of impedance threshold device during spontaneous ventilation (Other)
结局指标
主要结局
Estimated venous oxygen saturation
时间窗: From 5 to 6:59 minutes after applying the impedance threshold device
Oxygen saturation will be calculated from the five minute period of time prior to use of the impedance threshold device (0-4 mins), and then again in the 2 minute period after the impedance threshold device is applied (5-6 mins)
