I'll tell you about this movie rebreather I made, which depicts a Soviet rebreather from the 1940s. It's made from a life-worn IPSA.
There were two such movie rebreathers on the set of "Admiral Kuznetsov", which I prepared for filming. One was my life-worn IPSA, and the other was an even more life-worn IPSA from the film studio.
It works in an open cycle. Air is supplied from an external cylinder with a reducer through ... a water tap.
The tap supplies gas for inhalation through a hose into a gas mask. The valve box is an imitation - one of the hoses goes through it and ends with a ni**le with a gas mask thread.
In order to breathe in such a device, a good level of self-control is required, since you can inhale only when you open the tap. You can't open the tap for constant supply - the gas mask easily flies off your head as soon as excess air appears in the mask. You need to open the valve just enough so that all the air supplied ends up in your lungs.
It's even more difficult in the frame - you can't exhale while the shooting is in progress, so as not to spoil the picture with bubbles. We had stuntmen with good freediving training working with these devices.
