Oxygen Delivery Systems. Continuous flow. This system delivers a continuous flow of oxygen from the storage container. It is a very economical system in that it doesn’t need complicated masks or regulators to function. But it is also very wasteful—the flow of oxygen is constant whether you’re inhaling, exhaling, or pausing in between breaths.
