PFT Overview
Pulmonary function tests measure lung volumes airflow and diffusion capacity to evaluate respiratory health.
Diagnostic Value
PFTs help diagnose obstructive restrictive and mixed lung disorders by analyzing airflow patterns and lung capacity.
Testing Techniques
Common tests include spirometry lung volume measurement and diffusion capacity assessment.
Interpretation Principles
Interpretation requires comparing results to predicted values based on age sex height and ethnicity.
Clinical Application
PFT results guide treatment decisions and monitor disease progression.
