What is the primary purpose of medical gases in healthcare?

The primary purpose of medical gases in healthcare is to support patient breathing and provide therapeutic interventions. Medical gases, such as oxygen and nitrous oxide, play a crucial role in respiratory therapy and anesthesia, ensuring that patients receive the necessary support for effective breathing and comfort during procedures. Oxygen, in particular, is vital for treating various respiratory conditions and can aid in maintaining adequate oxygenation in patients, especially in critical situations.

While other options touch on important aspects of medical care, they do not encompass the primary function of medical gases. Diagnostic testing, sanitization of equipment, and enhancement of imaging techniques involve different processes and technologies unrelated to the fundamental role of medical gases in patient care. The focus of medical gases is predominantly on sustaining life and managing health conditions directly related to respiration and therapeutic needs.
