Medical gas refers to a range of specialized gases used in hospitals and clinics for anesthesia, respiration, sterilization, and various treatments. These gases—such as oxygen, nitrous oxide, carbon dioxide, and medical air are manufactured, stored, and distributed under strict regulatory conditions. Their correct use is essential for safe and effective patient care. Medical gas systems ensure that healthcare professionals can administer life-supporting gases reliably and without interruption across different departments of a medical facility.
