Re: Low-Cost Arduino-Based Ventilator
#72This probably should have gone on the thread about flattening the curve not being enough. But. Where is the core team of 12 people plus 108 collaborators that should have been assembled a month and a half ago to figure out how to retune US manufacturing to start producing stripped down ICU beds and the supplies needed to keep them operational? This game is easy. The parameters are well understood. You could assign th…
In Norway at least it isn't the beds themselves that are the issue it's the infrastructure needed for this in the hospital rooms of which the most important seems to be oxygen outlets. I'm not sure how safe it is to hook up gas tanks directly to DIY respirators.
Not that we are in a shortage yet, there are only 50 people hospitalised but it's expected to rise.

Who would have thought that a loudmouthed self promoter with an overinflated sense of his own intelligence and a history of making thoroughly unrealistic and unscientific predictions would get this one wrong too?
> a history of making thoroughly unrealistic and unscientific predictions I thought you were going to say "a history of making thoroughly unrealistic goals come to fruition" because that seems more accurate.
How're those Mars flights treating you? https://nypost.com/2018/03/11/elon-musk-flights-to-mars-will...
Good place to hide out from COVID-19, I'd reckon.

Musk has missed just about every goal he's ever set by a wide margin and has only managed to pull through because hordes of taxpayers and investors continue to line up to dump money into his black hole projects on the back of his self-aggrandising.

#75For those of us outside the US/EU, can someone explain about the change in tone here on HN ? There was a similar post a few weeks back and top-voted comments were uniformly scornful about such DIY medical equipment, and about how a ventilator was just one component in the ICU ecosystem. Now, though, there is a complete 180 ? What gives ? There is also the question of supply-side issues - uCs and IC boards are overwhe…

First skepticism, then shallow takes, then acknowledgement and analysis, now frenzied problem solving. > a ventilator was just one component in the ICU ecosystem. Yes, the ventilator is a CPAP machine on steriods. The Respiratory Therapist, Intensivist and Critical Care Nursing staff are…
>It's not uncommon for one or more of these to have multiple touches per hour for evaluation and adjustment of the parameters
Maybe a stupid question, but why can't this be automated?

Devil's advocate: Why would a manufacturer consider damaging what is a potential mega cash cow? I read earlier that ventilators generally sell for $40-70,000USD to hospitals (who then go on to charge $20-40k for ventilator based treatment.) We're much better off right now with the government seizing the means of production and figuring out how to make as many as possible.

The US fed gov just tried to buy an early vaccine candidate “on unprecedented scale”. I’m not sure that they will do the same when shit hits the ventilators.

Yes, but everyone else in the space sector has missed by a bigger margin.
How’s the Bush Mars mission coming along? Bush senior that is, initiative announced 1989.

You mean the rockets which are half the cost of any other provider including both government and private launch agencies?
Or do you mean the car company which turned electric cars from a hippy fantasy into a rich person fantasy and just made its millionth vehicle?

The evidence was presented 50 years ago under the label of Soviet Union. USSR couldn’t produce shit.
During crisis times wild [T-34]( https://en.wikipedia.org/wiki/T-34 ) appears and overwhelms with numbers and firepower/versatility
Well ... kind of.
Stalin fleeced the Kuleks to pay for Americans to build factories just before WW2, after Ford's River Rouge industrial city was completed.
He did a good job on T-34 production, but around half of Soviet armaments came from the USA during WW2. The tanks were directly driven to the front - no parking lot needed! :)
Stalin is portayed as a monster because he was. But he was also the great leader his country needed at that time.

Yet they somehow beat the US to space. And for some reason the US is still buying rocket engines from Russia.

Somehow? With captured German rocket scientists.
Same as USA.
Re: Low-Cost Arduino-Based Ventilator
#80If you're interested we are working on various mechanical ventilator designs which don't require actuators or electronics. There are actually devices like that in the market, you can learn more in our collaboration docs: https://docs.google.com/document/d/1R25O2mKT3TfSjXTmheGEevIk... Edit: Another design we're considering based on an Army prototype: https://docs.google.com/document/d/1Hcuu-55q2a3_-LmBwg0uBdgM... If y…
As a member of that group, I honestly wonder what use our work will be due to regulations. Most hospitals cannot use uncertified equipment or software. I think however that there might be a large policy shift where these projects may become acceptable for use after some new or temporary legislation in 1-2 months. At that time, the projects may be extremely valuable
If its this, or triage, a bloody thump up should be sufficient. If the regulators dont like it, let them come down and out to review procedure.
