Which of the following is NOT a classification of medical gases?

Industrial gases are primarily used across various industries for purposes that are not related to medical treatment or patient care, such as manufacturing, welding, and chemical processes. Unlike therapeutic, anesthetic, and laboratory gases, which are specifically designed and regulated for safe use in medical environments, industrial gases lack the regulatory oversight and safety standards pertinent to medical applications.

Therapeutic gases, such as oxygen and carbon dioxide, are utilized for treatment and support of patients. Anesthetic gases, like nitrous oxide and halothane, are specifically formulated for use in medical procedures to induce anesthesia. Laboratory gases are often utilized in medical and scientific research, providing necessary conditions for testing and experimentation in medical settings. In contrast, industrial gases do not fit into the framework of medical applications, highlighting why they are not classified alongside the other categories of medical gases.
