Helium/Oxygen Mixture 70/30

What is this medication? Helium and oxygen mixture 70/30 is a therapeutic gas used to manage patients with severe respiratory distress or airway obstructions. By replacing the nitrogen in normal air with helium, the density of the gas is significantly reduced. This lower density allows the mixture to travel more smoothly and with less turbulence through narrowed bronchial tubes or the upper airway. Consequently, the patient does not have to work as hard to breathe, which helps prevent respiratory fatigue and improves the delivery of oxygen to the lungs. This medication is commonly utilized in clinical settings to treat conditions such as acute asthma attacks, exacerbations of chronic obstructive pulmonary disease, and airway swelling. It acts as a bridge therapy, providing immediate relief from the mechanical strain of breathing while other primary treatments like bronchodilators or steroids begin to work. It is typically delivered via a non-rebreather mask or a mechanical ventilator to maintain the specific 70/30 ratio required for effective treatment.
