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 …

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 …

BACKGROUND: Heliox and forward-leaning posture (torso inclined forward at 50–60° with
the elbows resting on the thighs) are adjuncts in the administration of nebulized …

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 …

The purpose of this study was to evaluate the efficacy of heliox-driven continuous nebulizers
in the management of moderate to severe asthma exacerbations in the Emergency …

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 …

Background In chronic obstructive pulmonary disease (COPD) the clinical efficacy of
bronchodilator therapy delivered via a nebulizer versus an aerochamber on FEV 1 is …

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

Studies of the efficacy of heliox in patients with severe asthma have shown mixed results.
Among the factors that are responsible for variable outcomes, the failure of heliox delivery …

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 …
