To administer the medication, the MDI is depressed once, resulting in the release of one dose of medication.

The exhaled breath exits the device through the valves rather than entering the chamber ...
Draeger Ray dive/surface valve with bite grip scuba mouthpiece, non-return valves, and breathing hoses. A breathing hose or sometimes breathing tube on a rebreather is a flexible tube for breathing gas to pass through at ambient pressure. They are distinguished from the low-, intermediate-, and high-pressure hoses which may also be parts of ...

If the breathing gas supply is depleted, the dose of fresh breathing gas decreases until the breathing supply is used up. The diver will notice the decreasing volume of gas available which signals the need to switch to an independent open-circuit bailout system, which is integrated into the rebreather mouthpiece as a bailout valve, or to ...
The device must have a pressure relief valve that opens at 60cm of water pressure to avoid over ventilation and trauma to the lungs. The (FROPVD) is contraindicated in adult patients with potential chest trauma and all children. Note: ( In cases with an apneic patient the best results will be achieved using the Two person bag-valve-mask technique.)
