Medical gas refers to gases that are used in healthcare settings for various therapeutic and diagnostic purposes. Common types of medical gases include oxygen, nitrous oxide, and carbon dioxide. These gases are essential for patient care, often used in procedures like anesthesia, respiratory support, and imaging. Medical gases are typically stored in high-pressure cylinders or supplied through pipelines in hospitals. They must meet strict safety and quality standards to ensure patient safety. Proper handling and administration of medical gases are crucial, as improper use can lead to serious health risks.
