The use of Heliox, a mixture of helium and oxygen, can significantly improve patient outcomes during airway procedures by enhancing gas exchange. Helium is a lighter gas compared to oxygen, allowing it to flow more easily through constricted airways. This reduces resistance during breathing and can help deliver oxygen more effectively to the alveoli, especially in patients with obstructive airway diseases such as asthma or COPD.

By improving the movement of gas in the lungs, Heliox facilitates better oxygenation and can lead to reduced work of breathing, allowing patients to maintain adequate oxygen levels with less effort. This is particularly beneficial during airway procedures, where rapid and efficient gas exchange is crucial. The lower density of Heliox, compared to regular air or even pure oxygen, decreases the turbulence of gas flow, making it easier for patients to breathe, thus contributing to a more favorable outcome during respiratory distress situations.

Consequently, the correct understanding is that Heliox can be a valuable adjunct in the management of patients during airway interventions by improving overall gas exchange and clinical outcomes.
