Pulmonary Function Test (PFT) Interpretation Calculator





Formula

The formula to calculate the Pulmonary Function Test (PFT) Interpretation (PFT) is:

\[ \text{PFT} = \left( \frac{\text{FVC}}{\text{FEV1}} \right) \times 100 \]

What is PFT Interpretation?

PFT Interpretation refers to the analysis of Pulmonary Function Tests, which measure lung function and efficiency.

It helps diagnose respiratory conditions and monitor lung health, providing crucial information for treatment planning.

Example Calculation

Suppose a patient's Forced Vital Capacity (FVC) is 4.5 liters and their Forced Expiratory Volume in 1 second (FEV1) is 3.5 liters.

To calculate the PFT Interpretation:

\[ \text{PFT} = \left( \frac{4.5}{3.5} \right) \times 100 \approx 128.57\% \]

Therefore, the PFT Interpretation is approximately 128.57%.
