简要总结
The purpose of this study is to evaluate whether a correlation exists between the partial pressure of carbon dioxide existing within arterial blood and the gradient between inhaled and exhaled fractions of oxygen.

结局指标
主要结局
Correlate the level of carbon dioxide within arterial blood to inspired and expired oxygen gradient.
时间窗: At least 2 hours
Compare the levels of carbon dioxide found in the patient's blood to the amounts of carbon dioxide and oxygen in the air that the patient inhales and exhales. If a relationship exists between the levels of carbon dioxide in the blood and the levels of carbon dioxide and oxygen inhaled and exhaled by the patient, anesthesiologists will be able to use this relationship to adjust ventilators during anesthesia without having to take blood from an artery.
