Who among the following can receive medical gases?

Patients can receive medical gases with a prescription because medical gases, such as oxygen, are classified as prescription medications due to their potential risks and medical necessity. Prescriptions ensure that a licensed healthcare provider has evaluated the patient's condition and determined the appropriate use of the gas, safeguarding patient health.

In this context, it is important to understand that the regulation of medical gases emphasizes the oversight of their distribution to ensure they are used safely and effectively. Unlike some medical supplies that might be sold over the counter, medical gases require careful handling and monitoring, typically necessitating a prescription from a qualified healthcare practitioner. This prescription process is a key aspect of ensuring patient safety and adherence to legal frameworks regarding the distribution of medical treatment.

The other options imply either unrestricted access to medical gases or limit their availability solely to certain types of facilities or professionals, which does not align with current regulations regarding the handling of these substances.
