Objective: To propose and analyze a playful adaptation of the Forced Expiratory Technique (FET) in children based on a mechanism-oriented framework for airway clearance.
Methods: This is a descriptive theoretical-conceptual study based on the development and analysis of a pediatric clinical protocol incorporating playful strategies into FET execution. The components of the technique were mapped to their underlying physiological mechanisms according to contemporary classifications of airway clearance techniques.
Results: The proposed model suggests that the playful adaptation of FET is theoretically capable of activating key physiological mechanisms involved in airway clearance, including airflow modulation, increased lung volumes, and secretion mobilization. The integration of these components supports a multimodal physiological approache.
Conclusion: The playful adaptation of FET may represent a feasible and physiologically grounded strategy to enhance adherence and facilitate the execution of therapeutic breathing patterns in pediatric patients.
