Most of us have a minute vent respiratory volume measured in multiple liters for each breath. A micro fluidic pump cannot produce a volume that would sustain that, even if we account for removing the inefficiency of the intentional leak rate, tubing and other losses in the current CPAP systems. The people presenting this technology for crowd funding have not even produced a specification for what air volume and pressure they are able to produce. That would be a bare minimum beginning for me to consider this real.
I have seen a lot of buzz about this on social media, including facebook and the apnea forums. I have no doubt they will raise a lot of money, and that they will never put anything on the market that will benefit apnea patients. The mere promise is enough to raise million$$ from people who think this will revolutionize treatment. Many of the advocates have failed at CPAP and use full-face masks, which is not even part of the development at this point.
Think for a moment how fast a micro device would need to spin to produce a large air volume at pressure. Now imagine the sound of that on the end of your nose. We haven't even talked about the battery needed to power it. A watch battery is not going to go far, so a whole new technology is needed. Vapor ware.
