I assume this is the issue:

From a quick overview I don't think VAP will be a more serious issue for the proposed device than the commercial ones.
The microbes would come from two sources: Inside the system (from a prior patient), and from the air supply.
The former can be mostly prevented by replacing the bag and the tracheal tube, because both are cheap and disposable. Then there are probably some connection pieces and those need to be sterilized or replaced between patients.
The air supply can be run through a relatively low-tech filter if absolutely necessary.

I was under the impression these bag mask valves have a filter to prevent contamination from getting back in the bag but seems like its safe to just dispose, given adequate supply.

I think the concern was about the widespread use of ventilators in general, whether they are commercial or not.

cheap and disposable like the N95 masks? Does anyone manufacture these bags and tubes in your country at scale?

Not quite that disposable, but one per patient isn't really a big ask.
I'm curious how that would work out. I think it would have to do with the drugs that are given along side the ventilator, not from the ventilator itself?
>I hope we don't fixate on ventilators too much.
It feels to me like we might be. It'll definitely be needed, but I think there are other issues that aren't getting as much attention; problems that might not seen as solvable by someone in their garage with a 3d printer and some pneumatic valves.
