Pulmonary Function Testing

Pulmonary Function Tests (PFT)

Pulmonary Function Tests (PFT) are non-invasive tests that measure how well the lungs function. They help diagnose lung conditions, monitor disease progression, and guide treatment plans.

1. Types of Pulmonary Function Tests

Spirometry:

  • Purpose: Measures how much and how fast air is exhaled.
  • Parameters Measured: Forced Vital Capacity (FVC), Forced Expiratory Volume in 1 second (FEV1).
  • Clinical Use: Diagnoses asthma, COPD, and restrictive lung diseases.

Body Plethysmography:

  • Purpose: Measures lung volumes, such as Total Lung Capacity (TLC) and Residual Volume (RV).
  • Clinical Use: Diagnoses restrictive diseases and assesses hyperinflation in COPD.

Diffusion Capacity (DLCO):

  • Purpose: Assesses gas exchange efficiency.
  • Parameters Measured: DLCO (Diffusion Capacity of the Lung for Carbon Monoxide).
  • Clinical Use: Diagnoses conditions like pulmonary fibrosis and emphysema.

Peak Expiratory Flow (PEF):

  • Purpose: Measures how fast a person can exhale, typically used to monitor asthma.
  • Clinical Use: Home-monitoring for asthma patients to detect early signs of worsening lung function.

Lung Volume Measurement:

  • Purpose: Provides detailed lung capacity data, measuring Functional Residual Capacity (FRC) and Inspiratory Capacity (IC).
  • Clinical Use: Differentiates between obstructive and restrictive lung diseases.

2. Indications for Pulmonary Function Testing

  • Symptoms of lung disease (e.g., chronic cough, wheezing).
  • Chronic conditions like asthma, COPD, or pulmonary fibrosis.
  • Preoperative evaluation, especially for respiratory risk patients.
  • Occupational lung disease or long-term smokers.

3. Preparation for Pulmonary Function Tests

  • Avoid Smoking: No smoking for 4-6 hours before the test.
  • Inhalers: Patients may need to avoid bronchodilators unless otherwise instructed.
  • Wear Comfortable Clothing: To avoid restricting breathing during the test.

4. Benefits of Pulmonary Function Testing

  • Early Diagnosis: Detects lung issues before symptoms appear.
  • Monitoring: Tracks disease progression and treatment effectiveness.
  • Personalized Treatment: Results help guide individualized treatment plans.

5. Risks and Considerations

  • Minimal Risk: PFTs are non-invasive and generally safe, though some may experience mild shortness of breath.
  • Not for Acute Conditions: Individuals with respiratory infections or severe heart conditions may not be ideal candidates for PFTs.
