Somebody else also came up with this suggestion earlier in this thread but I didn't see any subsequent discussion about the idea (I've tried to read all postings -- difficult at times -- very, very helpful!).

Thank you!  Carl

Here is a link to another thread...

The one thing I am wondering is if there are other materials than specific NXX be "somewhat" effective.  People are using dense cotton, but I'm not sure that is much better than nothing.  But, for example, can EVA foam or wetsuit neoprene work to some extent?

Is there any merit what-so-ever that material density (weave?) indicates resistance to particle size?

While this is bordering on the ridiculous, could 5 layers of even tissue paper provide a barrier?

RE: CPAP use for Coronavirus mitigation & severe pneumonia
Here is an article that just came out yesterday from eurekalert.org/pub

ESA (European Society of Anaesthesiology)

CPAP (continuous positive airway pressure) breathing devices may delay respiratory failure, and help medical staff (also non-ICU experts) to avoid ICU admission when intubation is not feasible.

Thanks Cryonix, great job. It's 01:20 here now so I'll read it in the morning.

RE: CPAP use for Coronavirus mitigation & severe pneumonia
I agree with everything you just said… You got to do what you Gotta do.

I was only speaking from my personal standpoint and where possible trying to buy from a North American distributor.

It is probably also the case that many of the parts inside of both my machines are made in China.

Certainly not blaming anyone for being forced to buy from a certain supplier, but I think you know what I’m saying…

Yep, I hear 'ya 3rdMarDiv. I completely agree that if I can purchase stuff made here, it's much better. That's my usually strategy when buying products anyway. I'm just lamenting the fact that our once great manufacturing base here in the U.S. is all but gone now. That's what's causing us a lot of grief now during this crisis, with lack of pharmaceuticals, consumer products and other items we now outsource to China and other countries. I think that will change soon after this crisis is over, hopefully.

Nice catch John…! That is very encouraging information… Worse comes to worse… We have a effective tool in our homes.

My next curiosity is how they are deploying them and utilizing them… What are their procedures and protocol.

Thanks again

From what I've seen from RT's discussing vent management for covid-19...they emphasize high PEEP (being the most crucial parameter), controlling the max inspiratory pressures to prevent lung injury, moderate tidal volumes, higher than normal set respiratory rate, placing patients in the prone position being crucial for oxygenation, and sedation/neuromuscular blockade so the patient doesn't fight the vent and it somehow helps keep the peak pressures from spiking maybe due to asynchrony.

RE: CPAP use for Coronavirus mitigation & severe pneumonia
I'm going to ask again, after reading cryonix' translation of that Breathing Project document:

They're working really hard to create a mechanical device to attach to a CPAP machine that will allow for IPAP of 20 and EPAP of 6

Isn't this just reinventing the wheel? Bilevel machines exist in large quantities in the world and do this already. Why aren't we just using them?
