What is the primary reason for using medical gases?

The primary reason for using medical gases is to ensure adequate oxygenation for patients. Oxygen is essential for cellular metabolism and overall physiological function, making its administration critical in various medical scenarios, including respiratory distress, anesthesia support, and during surgeries. Ensuring that patients receive sufficient oxygen prevents complications arising from hypoxia (lowered levels of oxygen in the tissues), which can lead to serious health issues.

While other options mention important aspects of medical gas use, they serve more specific roles within the context of patient care. For instance, aiding in surgical procedures, decreasing recovery time, and maintaining sedation levels are important applications of medical gases, but they are not the primary objective. The underlying goal remains the same across different medical contexts: to provide adequate oxygen to support life and promote healing.
