Introduction:
The partial pressure of oxygen in the sea is about 100 mm Hg while that in a solution is equal to 3 mL O2/L of blood. Oxygen is carried by the blood in two forms, that is, the dissolved form and bound to Hb (hemoglobin).
Please refer to Clinical Application Case-2 for further information.
Explanation of Solution
The total oxygen content of arterial blood is denoted by
Putting the values of Hb as 15 g/dL,
Putting the values of Hb as 15 g/dL,
Total oxygen delivery can be calculated by using the following formula:
Putting the values of QT as 3.83 and
Putting the values of QT as 3.1 and
The difference between
The best PEEP was 5 cm
Therefore, it can be concluded that the best PEEP was 5 cm
