Calculate Fio2/Pao2 Ratio



Formula

The formula to calculate the Fio2/Pao2 ratio (R) is:

\[ R = \frac{P}{F} \]

Where:

Definitions

Example

Let's say the partial pressure of oxygen in arterial blood (Pao2) is 80 mmHg and the fraction of inspired oxygen (Fio2) is 0.21. Using the formula:

\[ R = \frac{80}{0.21} \]

We get:

\[ R \approx 380.95 \]

So, the Fio2/Pao2 ratio is approximately 380.95.

PaO2/FiO2 Ratio

Definition: The PaO2/FiO2 ratio is a measure of the efficiency of oxygen transfer in the lungs.

Formula: \( \frac{PaO2}{FiO2} \)

Example: \( \frac{80}{0.21} \)

PaO2/FiO2 Ratio in kPa

Definition: The PaO2/FiO2 ratio in kPa is used to assess the oxygenation status in patients using the metric system.

Formula: \( \frac{PaO2}{FiO2} \)

Example: \( \frac{10.6}{0.21} \)

SpO2/FiO2 Ratio

Definition: The SpO2/FiO2 ratio is an alternative to the PaO2/FiO2 ratio, using oxygen saturation instead of partial pressure.

Formula: \( \frac{SpO2}{FiO2} \)

Example: \( \frac{95}{0.21} \)
