What Is a Pulmonary Function Test?

Pulmonary function testing is a group of non-invasive tests that assess how air moves in and out of your lungs and how effectively your lungs deliver oxygen to your body.

These tests provide detailed information about lung performance, including:

  • Airflow and lung volume
  • Gas exchange and oxygen levels
  • How your lungs respond during breathing

Results help identify patterns that may point to specific respiratory conditions.

What Pulmonary Function Testing Evaluates

Pulmonary function testing provides insight into how your lungs are functioning and where breathing issues may be occurring.

Airflow and Breathing Patterns

Assess how air moves in and out of your lungs and identify patterns that may be linked to conditions such as asthma or COPD.

Lung Volume and Capacity

Measure how much air your lungs can hold and how effectively they expand and contract during normal breathing.

Obstructive and Restrictive Patterns

Identify whether airflow is limited or lung expansion is reduced, which can point to different types of lung conditions.

Changes Over Time

Track lung function across visits to monitor progression and evaluate how your condition responds to treatment.

This information helps your provider better understand your symptoms and determine whether further evaluation or treatment may be needed.

When You May Need Pulmonary Function Testing

Ongoing Shortness of Breath

If you feel winded during routine activities or notice a change in your breathing, testing can help identify the cause.

Persistent or Unexplained Cough

A cough that does not go away or has no clear cause may require further evaluation to assess underlying lung function.

Wheezing or Chest Tightness

Wheezing and tightness may be linked to airway changes that can be evaluated through pulmonary testing.

Monitoring a Known Lung Condition

If you have been diagnosed with asthma, COPD, or another lung condition, testing can track changes and guide care.

Before or After Starting Treatment

Pulmonary function testing can be used to establish a baseline and measure how well treatments are working over time.

Pre-Surgical or Routine Evaluation

In some cases, testing is recommended before surgery or as part of a broader health assessment to evaluate lung function.
