Variation of venous admixture, SF6 shunt, PaO2, and the PaO2/FIO2 ratio with FIO2.

We used a mathematical model of an inhomogenous lung to predict the effect of increasing inspired oxygen concentration (FIO2) on: (1) venous admixture (Qva/Qt); (2) arterial oxygen partial pressure ...

Variation in the PaO2/FiO2 ratio with FiO2: mathematical and experimental description, and ...

Previous studies have shown through theoretical analyses that the ratio of the partial pressure of oxygen in arterial blood (PaO2) to the inspired oxygen fraction (FiO2) varies with the FiO2 level.

呼吸不全とは？

1．室内空気吸入時の動脈血O2分圧が60Torr以下となる呼吸器系の機能障害またはそれに相当する異常状態を呼吸不全と診断する． 2．呼吸不全の型を2型に分け，動脈血CO2分圧が45Torrを超えて異常な高値を呈するものとしからざるものとに分類する． ...

Lung Injury Is a Predictor of Cerebral Hypoxia and Mortality in Traumatic Brain Injury

Background: A major contributor to unfavorable outcome after traumatic brain injury (TBI) is secondary brain injury. Low brain tissue oxygen tension (PbtO2) has shown to be an independent predictor of ...
