About

Background: Nebulizers design influences efficiency of aerosol delivery. Performance of nebulizers is commonly tested by breathing simulators with static parameters. However, breathing patterns vary in adults.

Objectives: The purpose of this study was to evaluate drug deposition of different types of nebulizers testing with breathing patterns of healthy subjects.

Material and Methods

The study was approved by Chang Gung Memorial Foundation Institutional Review Broad. Ten healthy subjects, aged 20.6±0.5 years, were recruited. Four nebulizers:

a constant jet nebulizer (Neb-easy, Galemed Corp., Taiwan); a breath enhanced nebulizer (Pari LC plus, Pari Inc., Germany); a manual-actuated nebulizer (A-T Neb, Atlantean Corporation, Taiwan); and a breath-actuated nebulizer (AeroElipes, Trudell Medical Inc, Canada) were evaluated.

Aerosolized drug depositions

Experimental group

Description:

Aerosol drug deposited on the inhaled and exhaled filters and the residual dose were evaluated delivered by four types of nebulizer: 1) a constant jet nebulizer, a breath enhanced nebulizer, a manual-actuated nebulizer, and a breath-actuated nebulizer.

Treatment:

Device: Breath enhanced nebulizer

Device: Manual-actuated nebulizer

Device: Breath-actuated nebulizer

Device: Constant jet nebulizer
