Area of Science:

• Pulmonary Medicine
• Respiratory Physiology

Context:

• Pulmonary functional tests (PFTs) are crucial for diagnosing and managing chronic respiratory diseases.
• Interpretation of PFTs relies on international guidelines from societies like the American Thoracic Society (ATS) and European Respiratory Society (ERS).
• The ATS/ERS established updated PFT interpretation standards in 2022, succeeding the 2005 guidelines.

Purpose:

• To provide a comprehensive synthesis of the five-step PFT interpretation process.
• To guide clinicians in applying the ATS/ERS-2022 standards for PFT analysis.
• To ensure accurate and consistent interpretation of spirometry, plethysmography, and DLCO measurements.

Summary:

• The ATS/ERS-2022 PFT interpretation involves five key steps: comparing results to reference values, identifying ventilatory impairments (obstructive/restrictive), assessing severity, evaluating bronchodilator response, and tracking changes over time.
• This systematic approach ensures a thorough evaluation of lung function.
• The guide emphasizes the importance of longitudinal data for detecting significant PFT parameter changes.

Impact:

• Facilitates more accurate diagnosis and management of chronic respiratory conditions.
• Promotes standardized interpretation of PFTs globally, improving patient care consistency.
• Aids healthcare professionals in utilizing the latest ATS/ERS guidelines for optimal clinical decision-making.
