During severe acute asthma exacerbations, it has been found that albuterol nebulized with Heliox leads to a more significant improvement in spirometry when compared with albuterol nebulized with oxygen because the low-density gas improves albuterol deposition in the
Inhalation of Heliox results in significantly lower turbulence, particularly in the more distal portions of the lung. The decreased turbulence results in an increased flow by up to 50% during Heliox inhalation.
Evidence continues to evolve that heliox can effectively reduce airway resistance and work of breathing in patients with severe airway obstruction and can improve delivery of aerosol by reducing turbulence and aerosol particle impact en route to the lungs.
