Insights
Cardiopulmonary exercise testing (CPET) offers valuable insights into pediatric respiratory diseases. Updated recommendations are needed to reflect its expanding clinical applications and novel metrics for dynamic abnormality detection.
Area of Science:
- Pediatric Pulmonology
- Cardiopulmonary Physiology
- Diagnostic Testing
Background:
- Cardiopulmonary exercise testing (CPET) is crucial for assessing functional limitations in pediatric respiratory diseases.
- Novel applications reveal dynamic abnormalities missed by static tests.
- Updated guidelines are necessary due to clinical importance and new research.
Purpose of the Study:
- To provide an updated review on CPET applications in pediatric respiratory diseases.
- To cover physiological differences between children and adults.
- To discuss novel CPET metrics and emerging technologies.
Main Methods:
- Narrative review of literature up to April 2025.
- Focus on pediatric respiratory diseases.
- Inclusion of physiological differences, non-traditional metrics, and reference values.
Main Results:
- CPET is a potent tool for assessment, evaluation, and diagnosis in pediatric respiratory diseases.
- Standardized protocols, age-specific values, and novel parameters improve clinical utility.
- Emerging trends include AI integration and CPET for younger children.
Conclusions:
- CPET is essential for diagnosing pediatric respiratory conditions.
- Standardization and novel metrics enhance its clinical value.
- Future research should focus on AI, interpretation refinement, and broader age applicability.
Introduction:
Cardiopulmonary exercise testing (CPET) is a diagnostic-integrated tool for evaluating cardiovascular, ventilatory, and metabolic functional limitations in children with respiratory diseases. Recently, novel applications have emerged, revealing dynamic abnormalities that may go unnoticed in standard static cardiac and pulmonary function tests. Given its clinical importance and novel research findings, updated recommendations are warranted.
Areas Covered:
We conducted a narrative review based on a literature search up to April 2025. This review provides an update on the application of CPET in pediatric respiratory diseases, covering physiological differences to adults, non-traditional CPET metrics such as the oxygen uptake efficiency slope (OUES), tidal volume to inspiratory time ratio (VT/Ti), and recent reference values. Indications, contraindications, and standardized protocols are discussed, alongside emerging trends in CPET technology.
Expert Opinion:
CPET is a potent tool for assessing, evaluating, and diagnosing pediatric respiratory diseases. Standardized protocols, age-specific reference values, and novel CPET parameters enhance clinical utility. Future research should refine interpretation, integrate artificial intelligence for data analysis, and facilitate CPET for younger children.

01:25Pulmonary Function Tests
Pulmonary Function Tests are crucial diagnostic tools for assessing respiratory function, particularly in patients with chronic respiratory disorders. They comprehensively evaluate lung volumes, ventilatory function, breathing mechanics, diffusion, and gas exchange. These tests help diagnose pulmonary diseases and play a significant role in monitoring disease progression, evaluating disability, and assessing response to therapy.

Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
