There are theoretical benefits of delivering drug aerosols to patients with asthma and
chronic obstructive pulmonary disease (COPD) using Heliox as a carrier gas. The objective …

Objective To evaluate nebulizer performance when heliox was used to power the nebulizer.
Methods Conventional and continuous nebulizer designs were evaluated. The conventional …

An MRI-based model of the mouth, throat, and upper airways of a 5-year-old boy is used to
evaluate methods for increasing the nebulized drug dose delivered to the lungs. Four …

BACKGROUND: Heliox (helium-oxygen mixture) has been shown to reduce turbulence and
improve aerosol delivery in a range of clinical settings. We questioned whether heliox as …

BACKGROUND: A new holding chamber was designed to be used with a vibrating mesh
nebulizer to increase the total inhalable dose for patients. It facilitates intermittent and …

Background: The bench experiments presented herein were conducted in order to
investigate the influence of carrier gas, either medical air or a helium–oxygen mixture (78 …

Heliox improves lung deposition of inhaled particles when compared with air or oxygen
inhalation. We studied the spirometric effects of albuterol nebulized with heliox during …

Medical aerosols may be delivered in combination with gases other than air, thus it is of
interest to assess the effects of gas properties on the characteristics of the administered …

Aerosol drug delivery using helium-oxygen gas mixtures (heliox) is considered in terms of
flow physics, atomization, and aerosol mechanics. Theoretical considerations are then …

Our understanding of albuterol nebulization driven by helium-oxygen mixture (heliox) has
matured with recent advances in clinical therapy, delivery systems, and understanding of …
