While administration of medical aerosols with heliox and positive airway pressure are both
used clinically to improve aerosol delivery, few studies have differentiated their separate …

To compare the effects of heliox-driven (He 80: O2 20) to air-driven (N 79: O2 21) β2-agonist
aerosol therapy on pulmonary function tests (PFTs) in patients with asthma, a prospective …

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 …

To compare the deposition patterns of heliox-driven and air-driven radiolabeled
bronchodilator aerosol, a prospective randomized study was undertaken at the Ben Taub …

Background This study compares the effect of heliox-driven to that of air-driven
bronchodilator therapy on the pulmonary function test (PFT) in patients with different levels …

Study objectives To evaluate the effect of heliox on airflow obstruction and dyspnea in
patients with acute severe asthma. Design A prospective, randomized, controlled study …

We examined systematically all controlled and cross‐over randomised trials in patients with
acute exacerbations of asthma and chronic obstructive pulmonary disease comparing …

Aerosol drug administration using helium-oxygen mixtures as a carrier gas has been
advocated in the treatment of severe airway obstruction. Helium's low density has been …

Objective To evaluate, by systematic review, the efficacy of heliox on respiratory mechanics
and outcomes in patients with acute asthma. Methods The search strategy included …

Objective To evaluate the effectiveness of a helium-oxygen mixture (79% He-21% 02) as an
aerosolizing compressed gas for β2-agonist therapy in patients with an asthma …
