How are medical gases commonly supplied?

Medical gases are supplied in various formats to accommodate different needs and settings within healthcare. The correct answer outlines the comprehensive ways in which medical gases can be delivered.

Compressed gas cylinders, or "tanks," are a widely recognized method, providing a portable and readily accessible source of medical gases like oxygen or nitrous oxide. They can be utilized in hospitals, emergency services, and even in home care settings, showcasing their versatility.

Bulk storage systems are another critical component, often used in larger facilities where a higher volume of gas is needed. These systems typically consist of large tanks that hold significant quantities of gas and are piped directly into the facility, allowing for continuous supply without the need for frequent cylinder changes.

Liquid thermoses, also known as cryogenic containers, are specifically used for transporting liquid medical gases, especially those that need to be kept at extremely low temperatures, like liquid oxygen.

Finally, portable home systems are designed for patients who require medical gas therapy in their residences. These systems provide convenience and ease of use, allowing patients to manage their therapy in the comfort of their own homes.

Together, these methods ensure that medical gases are efficiently and effectively delivered to meet the diverse needs of patients in various environments.
