This pulmonary function tests (PFTs) calculator determines the most commonly tested respiratory parameters and capacities based on easily obtained data and volumes.
This pulmonary test analyzer will help you understand your FVC, FEV1, VC, and other pulmonary test results. Select a test and enter your lab value to learn more.
Using the PFT (Pulmonary Function Test) Calculator. The PFT Calculator is a tool designed to assist in evaluating lung function by taking inputs such as age, height, gender, FEV1, and FVC to calculate predicted values and percentages. Below is a step-by-step guide on how to use this calculator effectively. Step 1: Input Personal Details
Lung function data were collated and prediction equations derived using the LMS method, which allows simultaneous modelling of the mean (mu), the coefficient of variation (sigma) and skewness (lambda) of a distribution family.
This FEV1 FVC ratio calculator determines the ratio of the forced expiratory volume in the first second to the forced vital capacity of the lungs.
Pulmonary Function Test Interpretation (PFT): The PFT Interpretation Calculator is a valuable tool used in respiratory medicine to assess lung function based on key metrics such as Forced Vital Capacity (FVC) and Forced Expiratory Volume in the first second (FEV1).
The FEV1/FVC ratio calculator allows you to compute the real-life Tiffneau index and predict the possible result based on your patient's age and height.
Spirometry Reference Value Calculator. Enter Age, Height, Gender and Race. To see Percent Predicted, you must enter observed FVC, FEV1, and FEF25-75% values in the appropriate boxes. Click Calculate to calculate the predicted values.
High-quality, office-based spirometry provides diagnostic information as useful and reliable as testing performed in a pulmonary function laboratory.
In practice, spirometers and pulmonary function test equipment have software that uses reference equations for calculation of "predicted values," as determined by published studies of large numbers of healthy individuals .
