[Pulmonary function test: The testing of children]

Area of Science:

• Pediatric Pulmonology
• Respiratory Medicine

Context:

• Pulmonary function tests (PFTs) are crucial in pediatric care, primarily for asthma diagnosis and follow-up.
• Assessing respiratory symptoms and functional impairment aids in establishing prognosis and guiding preventive strategies.

Purpose:

• To outline the requirements and methodologies for performing PFTs in children aged three and above.
• To detail the progressive development of PFT techniques suitable for pediatric patients as they mature.

Summary:

• PFTs can be initiated from age three with appropriate techniques, equipment, and trained personnel.
• Early PFTs include tidal breathing measurements (Rrs, Rint, sRaw) and functional residual capacity.
• As children mature, more complex tests like spirometry and plethysmography become feasible, adhering to international pediatric PFT guidelines.

Impact:

• Ensures accurate and reproducible PFT results in children, crucial for effective respiratory disease management.
• Facilitates early and precise diagnosis, prognosis, and tailored interventions for pediatric respiratory conditions.
• Standardizes pediatric PFT practices, improving the quality of care and research outcomes in pediatric pulmonology.
