Evaluation of Time-Sensitive Nebulization Mode Converter

Brief Summary

This study utilizes a randomized crossover design to evaluate and compare the clinical and technical efficacy of different nebulization modes for aerosol drug delivery. By implementing a within-subject comparison, each participant will receive the two designated aerosol delivery interventions under distinct, controlled protocols. The primary objective is to determine whether synchronization of aerosol generation with the inspiratory phase could improve respirable aerosol delivery, enhance pulmonary drug deposition, and reduce aerosol loss during exhalation without significantly altering aerosol aerodynamic particle size distribution characteristics. This research aims to optimize nebulization practices and establish evidence-based guidelines for enhanced respiratory drug administration.
