Calculate the P/F ratio using the following:

P-Pa02 82

F-F102 60%

The P/F ratio is used to assess the degree of hypoxemia in patients, particularly those with acute respiratory distress syndrome (ARDS). A P/F ratio of less than 300 suggests mild ARDS, less than 200 suggests moderate ARDS, and less than 100 indicates severe ARDS.

Given:

PaO₂ (Partial pressure of oxygen in arterial blood) = 82 mm Hg

FiO₂ (Fraction of inspired oxygen) = 60% = 0.60 (in decimal form)

Answer and Explanation

The Correct Answer is ["136.67"]

Calculation:

The P/F ratio is calculated as:

P/F ratio= PaO₂÷ FiO₂

P/F ratio = 82÷0.60

=136.67
