Medical gases are specialized gases used in healthcare settings for various purposes, including patient treatment and diagnostics. Common examples include oxygen, which supports breathing, and nitrous oxide, often used for pain relief during procedures. These gases are typically stored in high-pressure cylinders and must be handled with care to ensure safety. In addition to oxygen and nitrous oxide, other medical gases include carbon dioxide for insufflation during surgeries and helium for certain respiratory treatments. Each gas has specific applications and is regulated to ensure quality and safety in medical environments. Proper training is essential for healthcare professionals who work with these gases.
