I don't understand why he has connected a 3KV electrophoresis supply to the apparatus under the microscope. Some kind of micromachine that runs on such a high voltage is not very likely.
And here's what I think was in that giant wooden crate from a message postings back:

Looks an aweful lot like this: http://www.pva.net/products/Benchtop-Coating-Dispensing-System_116.htm
Good work!
Actually, that machine can be seen behind the crate. So crate must have had something else.

I don't get that either
The Airling doesn't add any moisture, so that is another reason to think it must only switch on when there is a breathing event. A constant pressure apnae machine with no moisture can get very uncomfortable.
The number seem very marginal at best, but it is not necessarily the same level of scientific dodgyness the uBeam, Batteriser and the Triton. If they can get the pump and the HV drive electronics right, it would be a very simple device that could be made cheaply.

Pumping non-humidified air through the nose is a non starter - it will quickly lead to cracked, bleeding nasal mucosa.
I have no idea of the number here, but if it was common to have 200 breathing interruptions a night

I don't think that is always true. There are people who need constant positive pressure. There are people who don't.
If it is not blowing dry air continuously into the nose, it will be no more drying then normal breathing.

Hey all. I am new here. I have some field experience repairing electronic devices. But a couple of things from scratch to make life easier and what not. So I am not a total newbie.
But I am scratching my head and wondering if anyone has thoughts on this product.

Airing: the first hoseless, maskless, micro-CPAP
My wife uses a CPAP and i just don't see how you can get the air-flow that a big machine produces in such a tiny package.
Not only that if it could generate the air pressure required how does it stay in the noise without blowing off ?

18 more months for this debacle to reveal itself for what it truly is....No need for 18 months. It is a very slick but obvious scam. CPAP requires several orders of magnitude more energy than any known battery that could possibly fit that form factor device mock-up. The powersupply for contemporary CPAP machines is similar in size and capacity to a laptop powersupply of 10 years ago. Could be 50 to 100 Watts for 8 hours.
There is no way the pressure required to hold the airways open could be overcome without a strap to hold the mask in place.

There is no way the pressure required to hold the airways open could be overcome without a strap to hold the mask in place.As I understand it, it does not need the same power as a CPAP because it does not work the way as a conventional CPAP. The pump only switches on when there is a CPAP event, and so the power consumed is dependant on how many CPAP events an individual person has and how long the Airling has to boost the pressure for each event. The airflow is less then a conventional CPAP since the conventional CPAP supply a lot of air that goes straight out of the mask vents. The CPAP machine is also still pumping when you are breathing out and the Airling concept does not do that. That is probably a 50% power saving.
The problems about the lack of a humidifier have been discussed before - it is probably only usable if you live in a location with a regular high humidity. When the air is dry, you would want to revert to a conventional CPAP with a humidifier.
Yes, discussed earlier and debunked. Humidity would need to be close to 100 % - maybe in a rainforest...
Yes, discussed earlier and debunked. Humidity would need to be close to 100 % - maybe in a rainforest...Well then I will have to debunk the debunkers. I have a CPAP and I was able to use it throughout summer with no humidifier without the slightest problem as long as the air is not heated. I have no airconditioning or heating in the bedroom so the air is at the normal outside humidity. If the bedroom was heated, I would need a humidifier.
When winter came, I did have to go back to the humidifier as I was waking up with a very dry nose and mouth. I live at about 1100 meters elevation and the humidity is typically 40% to 60%. It is almost never 100%.
. Fair enough. CPAP machines are only constant pressure because it is a very simple and very reliable way to achieve a result. It is not because a constant pressure is the only way to achieve the result.
And I do understand that CPAP does mean constant pressure and the Airling is not. Fair enough. CPAP machines are only constant pressure because it is a very simple and very reliable way to achieve a result. It is not because a constant pressure is the only way to achieve the result.
Well you're unusual then. Anytime I've seen it used without a humidifier for anything other than short periods - a few days -it is not tolerated at all - their nasal mucosa starts getting too dry. . That's in the pacific northwest USA - not a dry climate. But fair enough -I suppose I was being overly dramatic with the 100% figure. But it defies the reality of the physiology of nasal mucosa that you can run air over it at a significantly lower humidity (and high pressure) without drying it out. I think if you had a "microblower" trying to ramp up pressure quickly with every inspiration it would only be worse.

Based on what I've seen so far, the Airing is barely better than the Triton scam.
As you point out, the technical problems are huge if not unsurmountable, and then they have to convince the doctors and regulators that the device is safe.

One of the reasons for continuous positive airway pressure in the instance of obstructive sleep apnea is to prevent the obstruction from occurring in the first place as obstruction can occur both in the inspiratory and expiratory phases of the respiratory cycle. Example of obstruction during the expiratory phase is retropalatal narrowing - Starling Resistor.
The medical research needs to come first; the engineering of a particularly tiny implementation can come later, and representing a nonexistent implementation of an unproven treatment as effective is unethical.
