Year in Review: Pulmonary Function Testing

Area of Science:

• Pulmonology
• Respiratory Medicine
• Clinical Physiology

Background:

• Pulmonary function testing (PFT) has a long history, with many common tests developed before widespread computer use.
• Despite extensive use, optimal methods for performing, interpreting, and applying PFTs remain areas of active research and debate.

Purpose of the Study:

• To review recent publications on key aspects of pulmonary function testing.
• To discuss advancements in lung volume measurement, airflow obstruction classification, and bronchodilator responsiveness.
• To examine the implementation and impact of race-neutral reference equations in PFT.

Main Methods:

• Literature review of recently published papers in the field of pulmonary function testing.
• Synthesis of findings related to lung volume testing methodologies.
• Analysis of studies defining and grading airflow obstruction.
• Evaluation of research on the clinical utility of bronchodilator responsiveness.
• Review of studies on the development and application of race-neutral reference equations.

Main Results:

• Recent research continues to refine the performance and interpretation of lung volume testing.
• Newer definitions and grading systems for airflow obstruction are being explored.
• The clinical significance of bronchodilator responsiveness is under ongoing investigation.
• The transition to race-neutral reference equations is a significant development in PFT.

Conclusions:

• Continued research is essential to optimize pulmonary function testing practices.
• Standardization in performance, interpretation, and application of PFTs is crucial for accurate diagnosis and management.
• The adoption of race-neutral equations represents a move towards more equitable respiratory health assessment.
