What is a notable benefit of using helium-oxygen mixtures in some patients?

The use of helium-oxygen mixtures, often referred to as heliox, offers notable benefits, particularly in reducing airway resistance. Helium is a less dense gas compared to regular air, which allows it to flow more easily through constricted airways. This property makes heliox particularly advantageous for patients experiencing obstructive airway conditions, such as asthma or chronic obstructive pulmonary disease (COPD), where airway resistance is a significant concern.

By using helium-oxygen mixtures, clinicians can improve airflow and thus enhance the delivery of oxygen to the lungs without putting excessive pressure on the respiratory system. This is especially beneficial in emergent situations where rapid resolution of hypoxia is essential. The lower density of helium allows for more efficient ventilation, which can lead to better outcomes in these patients.

In contrast, while other options may seem relevant, they do not specifically highlight the primary advantage heliox provides in the context of airway management and respiratory ease.
