So, my practical engineering hat tells me to spec for the upper bounds here, so I'll calculate for:

| 0.75 litres | 30 breaths / sec | 1 : 2 | 1.125 litres / sec (2.34 cfm) |

(for reference) 1000 Pa is ~ 0.15 PSI. This sounds appropriate. [Inflatable Arenas](https://en.wikipedia.org/wiki/Air-supported_structure) using air pressure commonly only need ~250 Pa to stay up, but this relationship is dependent on the size (bigger: smaller pressures).

Finally, I am here to investigate what kind of fan / pump I need. My burning desire / hope is that I can use commonly available '5015' blowers:
