Right.

We know that the research actually explores between 1% to 4% of the fraction of inspired H2O.

So any nurse or doctor that especially works in ER knows what fraction of inspired O2 is.

You know, we need to know how much oxygen is actually getting into the system, right?

Not just what the flow rate is, right?

What the fraction of what someone is inspiring is that concentration.

So we need to ensure this fraction of inspired H2.

Right.

To know that whether it's a 90 year old grandma with lung cancer having a panic attack or a 300 pound healthy bodybuilder practicing deep breathing, that they are getting the same precise concentration with every breath.

And we ask the questions, how do we do this?

Because nobody's doing anything like this.

So our machine, first off, it's pulling in air and filtering it through a HEPA filter.

So it's cleaner air than the room you're in, and we're making our H2, and the H2 is variable.

So you can set it based on the power that'll go to the membrane, and it can be 1%, 1.1%, 1.3%, 2.2%, 2.8%, 3.2%, all the way up to 4%, so by 0.1% variabilities.

Now it's a closed system.

They mix and they go into an inflatable bag made of silicone that has a three liter capacity.

And we actually had to design a custom mask to make this work because we needed to make sure that it's a closed system.

Yeah.

That you were only getting your breath from this precise concentration of the machine.

So when you inhale, everything from that silicone bag that's been pre-mixed to that precise concentration comes through a one-way valve into a full face mask.
