@sonhouse saidIf it works as well as his vacuum cleaners, it'll ventilate the virus right back into the patient's lungs.

He is getting them into production as we speak. Er, type.....
The only Dyson product I've ever found to be effective are those hot-air hand dryers, and even those only work well if they're turned up hot enough - which they aren't nearly often enough.

@shallow-blue saidDyson vacuum cleaners are absolutely awesome when new.

But they don't last and nobody wants to repair them.

@wolfgang59 saidTrue story that. I did repair ours twice. Then I didn't get the required spare part...

@wolfgang59 saidSince the ventilators are to cope specifically with excess demand from covid-19 this isn't a problem, there's be a massive surplus after the disease fades and they won't be much use. So provided they work for as long as they're needed maintainability isn't an issue.

@deepthought saidWritten like a good capitalist...the surplus could proove to be an issue if we don't leran that preparedness is also of value.

@ponderable saidRight now ventilators are needed fast and at a capacity several times over what's normally required. The requirement is that the ventilators that can be made quickly, and preferably inexpensively but that's a secondary consideration. Under normal circumstances the NHS simply doesn't need a ton of spare capacity in one particular piece of equipment, they'll have some reserve capacity across the board and a way of getting new equipment with known characteristics. The catch with the Dyson ventilators is that they might work fine when they're new but in a year they can be mildly faulty with medical staff not used to spotting the problems with them. Now the requirement is for ventilators and the risks associated with their aging characteristics are irrelevant. After this the risks associated with how they behave as they age will matter.

@deepthought saidWhat if they all went back to dyson for a refurb and then put into storage for the next viral or bacterial outbreak.

I’ve had a dyson vacuum for about three years and it’s still doing its job but there are cheaper equivalents though.

@kevcvs57 saidI'm not making a comment about Dyson kit generally. They have some justification for wanting to make a new design and all engineering involves trade offs. I'm guessing that the trade off is a gain in ease of production against a sacrifice of service life.

If there's no gain in speed of production they may as well just build a standard model that won't need to go through the NHS validation procedure or involve any of the risks in building a new piece of kit. If they're reliable then the post-covid surplus could be put to use in other countries or international emergencies or just dismantled - if and when SARS-CoV-3 comes along we can expand capacity fairly quickly then, if my assumption that they're easy to make is correct.
There's problems having multiple different types of the same piece of equipment as the staff need to be trained in how to use each one, also it can really complicate logistics and I imagine that most people are of the same opinion as I am that money should be focused on patient care and not overcomplicated supply chains.

@deepthought saidI think most people that end up gasping for air will take whatever they can get but I take your point about the shortage of trained staff and that’s only going to get worse as the crises peaks, perhaps simplicity of operation should override durability. I saw a report about existing ventilators being adapted to enable them to ventilate several patients at once which would cut down the number of trained staff required per patient.

@Ponderable
So you whipped out your laser driven metallic 3D printer and MADE the part in true MacGyver style, right?😉
Seriously, a ventilator innards are not like a vacuum cleaner where the motor is spinning upwards of 20,000 RPM, it is a much gentler mechanical operation so if he makes them I suspect they will hold up.
Just remember, the output pressure of a ventilator is not like 200 PSI or anything close, more like 20 at best.

@sonhouse saidIt'd better not be 200 psi 'cos that'll be a total mess to clean up.
