Medical gases are essential substances used in healthcare settings for various purposes, including patient treatment and diagnostics. Common examples include oxygen, nitrous oxide, and carbon dioxide. These gases can be delivered through specialized equipment, such as gas cylinders and flow meters, to ensure accurate dosing and administration. In hospitals, medical gases play a crucial role in procedures like anesthesia and respiratory support. For instance, oxygen is vital for patients with breathing difficulties, while nitrous oxide is often used for pain relief during surgeries. Proper handling and storage of these gases are critical for safety and effectiveness in medical care.
