Ref the exhausting of face masks in the home environment:
Take a HEPA filter (3M purple) for home use. Cut it apart. Wrap it around a ball shape, tape/glue in place. Without the ball inside... place ball around the mask port and tape/seal into place. The HEPA filter will catch virus sized particles.
You would want enough volume to allow for exhale pressure.

If you have a tube, this sort of in-line filter might help.
The hospital machine in the video will be in-line for exhaust.
Anyone know the specs (ISO, industry) for HEPA filters?

HEPA filters remove 99.99% 0f particles 0.3 microns and smaller. They will not remove viruses particles but will remove the large droplets in which they are carried. Someone in a previous post mentioned using theHEPA filters from our CPAPs as exhaust air filters. The inlet filters on our machines don't come anywhere close to HEPA standards. They are just dust filters. All HEPA filters have a small amount of leakage, especially around the periphery which cannot be completely eliminated. They should not be considered sterilizing filters. I know this from 25 years of experience with clean rooms employed for the filling of sterile pharmaceuticals.

Supersleeper and everybody please have a look at this from the north of Spain:

Apnea board won't let me post links because I'm new.
FDA released new guidance yesterday
Enforcement Policy for Ventilators and Accessories and Other Respiratory Devices During the Coronavirus Disease 2019 (COVID-19) Public Health Emergency
Discusses use of CPAP/BiPAP.

Instead of just posting links, it might be helpful to include executive summaries or abstracts.
Give us the gist or the upshot or the takeaway.

Having agreed to the rules of Apnea Board, you'd have understood there'd be restrictions as a new member. As you are a member, this also means you've accepted those rules.
Regardless of your complaint, here's the link to the article I think you were referring to:

A fascinating thread, that echoes some of my own thoughts from a few days ago, ie what precisely is the difference between a ventilator and a CPAP machine.
What is needed is for one of the major CPAP vendors to contribute to the debate, and to explain definitively why using CPAP as a ventilator is, or is not, an idea worth pursuing. It might even be the case, for example, that a hidden menu option or PCB jumper on some models might enable features that could help. Such as disabling the safety feature which normally prohibits setting a pressure of more than 20. (Yes, there's an inherent risk in that, but we're more interested in saving lives than satisfying lawyers right now.)
