Helium, Oxygen

What is this medication? Helium and oxygen, commonly referred to as Helox, is a prescription medical gas mixture used to assist patients with severe breathing difficulties. Unlike atmospheric air, which consists mostly of nitrogen and oxygen, this mixture replaces nitrogen with helium. Helium is a low-density gas that allows the mixture to flow through narrowed or obstructed airways with significantly less turbulence. By decreasing the resistance of airflow, the medication helps to reduce the mechanical work of breathing for patients experiencing respiratory distress. This medication is primarily used in emergency or clinical settings to treat conditions such as acute asthma exacerbations, croup, and chronic obstructive pulmonary disease. It is also effective for managing upper airway obstructions caused by tumors or vocal cord dysfunction. By making it easier for oxygen to reach the lungs, Helox helps prevent respiratory failure and muscle fatigue while other primary treatments have time to work. It is typically administered through a specialized mask or a mechanical ventilator under the supervision of healthcare professionals.
