In the United States, what distinguishes a medical oxygen system from an emergency oxygen system?

The distinguishing factor between a medical oxygen system and an emergency oxygen system is the requirement of a prescription for medical oxygen. Medical oxygen is intended for patients with specific medical needs, such as those with respiratory conditions. This means that it must be prescribed by a healthcare provider, ensuring it is used safely and correctly as part of a treatment plan.

In contrast, emergency oxygen systems are designed for immediate use in crisis situations, such as in lifeguard scenarios or emergency medical care. These systems are accessible without a prescription, allowing first responders and trained individuals to administer oxygen quickly to individuals in distress. The focus of emergency oxygen is on providing immediate assistance, rather than on ongoing medical treatment, which is why a prescription is not necessary for their use.

The requirement for a prescription ensures oversight and regulation in the use of medical oxygen, highlighting its specialized application compared to emergency systems that prioritize rapid deployment for acute situations.
