What is the main benefit of using Heliox in respiratory treatments?

Using Heliox, a mixture of helium and oxygen, primarily offers the benefit of reducing turbulence of gas flow in the airways. This is due to the low density of helium compared to oxygen, which allows for smoother and more laminar flow of gas during respiration. This characteristic is particularly advantageous in conditions where airflow is obstructed, such as in cases of asthma or COPD, as it helps to improve airflow to the lungs and can facilitate easier breathing for patients experiencing respiratory distress.

While improving oxygen levels is important, Heliox itself does not directly enhance the amount of oxygen in the mixture; its main function lies in facilitating better gas delivery through the respiratory system. Additionally, Heliox might not have a significant direct effect on decreasing inflammation or improving pulmonary function in the way that medications specifically designed for those purposes do. Therefore, the primary benefit of its use in respiratory treatments is its ability to reduce the turbulence associated with gas flow.
