What is the typical concentration of Heliox used in treatments?

The typical concentration of Heliox used in treatments is 70% Helium and 30% Oxygen. This specific mixture is effective for optimizing respiratory therapies, particularly in cases of severe obstructive airway diseases, as it reduces the density of the gas being delivered. The lighter density of Helium allows for easier passage through narrowed airways, facilitating improved airflow and reducing the work of breathing.

In clinical settings, this concentration provides the benefits of better gas exchange and less resistance when patients are experiencing severe bronchospasm or other forms of airway obstruction. By using the 70/30 combination, healthcare providers aim to achieve a favorable therapeutic effect while maintaining adequate oxygenation in the patient.

The other options, while still combinations of Helium and Oxygen, either do not reflect the typical ratios used in practice or result in less effective treatment scenarios.
