Helium Oxygen Nitrogen mixture

What is this medication? A helium-oxygen mixture (Heliox) is a specialized medical gas used primarily to assist patients experiencing severe respiratory distress. This medication works by utilizing the low density of helium to decrease the resistance of gas flow within the airways. By making the gas easier to move through narrowed passages, the mixture reduces the physical effort required for a patient to breathe, which is particularly beneficial for those suffering from conditions like acute asthma exacerbations, chronic obstructive pulmonary disease, or various upper airway obstructions. This gas combination is typically administered through a tightly fitting mask or a mechanical ventilator in a hospital setting under close medical supervision.
