helium-oxygen mixtures

Helium-oxygen mixtures combine helium, a light, non-toxic gas, with oxygen, essential for breathing. These mixtures are often used in medical treatments, particularly for patients with respiratory issues, as they reduce the work of breathing and improve airflow. The lower density of helium makes it easier for patients to inhale, especially when under stress or with narrowed airways. Additionally, helium-oxygen mixtures are utilized in deep-sea diving to prevent the bends and are used in certain industrial applications. Overall, they enhance breathing efficiency and safety in specific environments.
