If you google 'ventilator tester' the result shows devices which presumably are the market we are aiming for. (they look similar to Ventitest in pictures). It seems these external devices are required for regular testing as described in website below under the heading 'volume'. I see in the specifications for Ventitest it includes a test lung which indicates its an external device.

Thus the market does seem large and if our technology is indeed superior then one would expect it would sell and attract attention from large manufacturers.
As much as I like biotech stocks, they have a high opportunity cost because they don't pay dividends and thus holding them always requires a leap of faith. Sometimes its hard keeping the faith if you're a longterm holder and nothing much happens, but I always sell and put my money elsewhere if I become cynical.
So I'm believing our technology does have advantages for now and not selling.
At the very least I'm keen to see the effect of recently being included in international clinical guidelines, which as the AR says, will drive sales on its own.
