How is medical air typically stored?

Medical air is typically stored in two primary forms: compressed gas in cylinders and produced on-site by air compressors. This method allows for the safe and efficient delivery of medical air with the necessary purity and pressure required for therapeutic use. The use of cylinders provides a convenient way to transport and store medical air, ensuring that it remains readily available for patient care in various medical settings.

The other options do not accurately describe the storage of medical air. Storing medical air solely in liquid form is impractical in most healthcare environments, as it is primarily utilized as a gas. Additionally, medical air does not exist dissolved in oxygen tanks, since these tanks are designed for oxygen storage specifically. Mixing medical air with carbon dioxide for storage is incorrect, as medical air consists of a specific mixture of gases mainly composed of nitrogen and oxygen without any intentional addition of carbon dioxide.
