PF Ratio Formula
The following formula is used to calculate the PF Ratio.
PFR = P/F
- Where PFR is the PF Ratio
- P is the arterial p02 (P)
- F is the fraction percent of inspired oxygen (FI02)
How to Calculate PF Ratio?
The following example problems outline how to calculate PF Ratio.
Example Problem #1:
- First, determine the arterial p02 (P).
- The arterial p02 (P) is given as: 86.
- Next, determine the fraction percent of inspired oxygen (FI02).
- The fraction percent of inspired oxygen (FI02) is provided as: .80.
- Finally, calculate the PF Ratio using the equation above:
PFR = P/F
The values given above are inserted into the equation below and the solution is calculated:
PFR = 86/.80 = 107.5
Example Problem #2:
For this problem, the variables required are provided below:
arterial p02 (P) = 90
fraction percent of inspired oxygen (FI02) = .70
Test your knowledge using the equation and check your answer with the calculator above.
PFR = P/F = ?
