The situation has caused them to temporarily suspend a lot of that, as it was hampering the production and supply of critical medical equipment we are short on.Cutting cost is mainly done by foregoing the couple-of-years spent on testing and validation before getting an FDA approval. (As is usually required. I don't know if there are any temporary changes in requirements.)
A respirator that meets the absolute barest requirements (only one mode, no feedback, minimal instrumentation and only the most basic adjustments by adjusting levers, weighs, valves, set screws, etc.) can be made from ~$200 worth of stuff from a hardware store as a dumb mechanical or pneumatic contraption.Cutting cost is mainly done by foregoing the couple-of-years spent on testing and validation before getting an FDA approval.

I gather that standard hospital ventilators need to be a swiss-army-knife, because hospitals often have only a few and need to use them to handle the gamut of different scenarios. So, perhaps the standard ventilators are something of a "Cadillac", when all we really need is a stripped-out Civic.A respirator that meets the absolute barest requirements (only one mode, no feedback, minimal instrumentation and only the most basic adjustments by adjusting levers, weighs, valves, set screws, etc.) can be made from ~$200 worth of stuff from a hardware store as a dumb mechanical or pneumatic contraption.
What drives cost and complexity up is making the smallest machine possible that can do every possible variant of every possible mode with all programmable parameters and all optional patient comfort without requiring that the operator also be a mechanic.
If mechanical engineers can put together engines, pneumatic and hydraulic systems that can handle extreme loads for hundreds of hours and billions of cycles on end between service intervals, they should be able to design something capable of reliably driving a flesh bag at a rate of one cycle per 6-10 seconds for days at a time with relative ease.However, I'm sure a lot goes into reliability, testing, and ensuring that the device will both provide adequate ventilation without over-pressurizing the lungs, not allowing mold to develop in the tubing/valves, and half-a-dozen other issues you probably haven't even thought of.
Given a choice between a hackspirator which can save lives when made well enough and certain death due no respirator at all, I'd take the hackspirator. That's the choice people currently have in places with overrun ICUs.Would anyone in their right mind actually want to be hooked up to this thing if their life depended on it?
Your lungs filling with fluid is a problem regardless of what other effects covid-19 may have elsewhere and respirators are something that we've been building for decades vs no known safe and effective treatment for its symptoms and no specific timeline for those either.I guess nobody told these guys that the real problem was that Covid-19 was displacing an iron ion in the blood, and that pneumonia wasn't actually part of the problem?
People get put on respirators when they cannot breathe on their own power anymore. You cannot find evidence of anyone disputing their usefulness because by the time they get put on it, the alternative is practically certain immediate death.I can't find a single article written in the last few days, or at all really, from anybody working in the thick of things, that indicates they believe ventilators are helping anybody at all.
https://threadreaderapp.com/thread/1247628906472980482.htmlCOVID-19 glycoproteins bond to the heme groups, and in doing so the oxidative iron ion is “disassociated” (released) from red blood cells.
Without the iron ion, hemoglobin can no longer bind to oxygen, rendering the red blood cells useless.
It is very likely that this is more the case, rather than developing a form of ARDS or pneumonia.
Many doctors are starting to believe that they are operating under a false notion of pneumonia, & possibly treating the wrong symptoms on a systematic basis throughout the country.
Ventilators may not be treating the root cause, as many of the patient’s lungs aren’t ‘tiring out’, they’re pumping just fine.
It is instead that the affected hemoglobin have been stripped of their ability to carry oxygen, resulting in hypoxia.
When you are at the stage where you cannot breathe on your own, no ventilator is a definitive death sentence - they literally require assistance with the mechanical function of breathing.Most doctors are saying that they do not believe that the people who ARE pulling through, wouldn't have pulled through anyhow even without a ventilator.
Without addressing the accuracy of your statement, rest assured that lots of people are tackling this virus from all angles.I guess nobody told these guys that the real problem was that Covid-19 was displacing an iron ion in the blood, and that pneumonia wasn't actually part of the problem?
Really? ThailandMedical.news? Had you ever hard of that site, before? Do you even have a clue if they're at all reputable?
I can't find a single article written in the last few days, or at all really, from anybody working in the thick of things, that indicates they believe ventilators are helping anybody at all. They all say exactly the opposite. If the doctors are saying this, then who is it that is saying these are needed and are helpful?
It's not as simple as that. The lung tissue is inflamed.We have ways to get fluid out of the lungs, and they don't involve the use of a ventilator for the most part.
Yes, there are risks. That & shortages are why ventilators are used as a last resort. Especially when they're in critically short supply.In some cases, the ventilator itself causes pneumonia, which may be part of the whole problem. I'm no doctor, I don't have answers.
Another sketchy link. Possibly worse than spreading misinformation, you could even spread malware like that.
No, it was debunked. The hemoglobin thing is fake news. That's why you can't find it reported from any reputable source.Those links are 100% valid data which you obviously didn't bother to look at before sounding off against them.
Twitter and youtube are not reputable sources. You can claim to be anyone, on Twitter. Youtube is so full of conspiracy theories that I call it ConspiracyTube. That "doctor" could be a Russian troll, for all we know. Even if he's a real medical doctor, there are a few quacks out there.Feel free to visit twitter or Youtube to view the actual content.
Why would I use that? If it's a reputable source, just post the original URL. I don't use intermediaries, like tinyurl and such.If you knew what threadreader was, you wouldn't even suggest that. It simply "unrolls" existing tweets into a readable web page.
That's exactly why you need to use reputable sources. Neither you nor I have the expertise to know, for sure, whether someone is a quack or not. Good reporting involves looking at & verifying someone's credentials and looking at their data, analysis, methodology, seeing if it scientifically holds water, and how it's regarded by their peers.Whatever though, any half intelligent person can create seemingly merited arguments against any fact, position or argument,
If you want to discuss this in good faith, please don't twist my words. I did not say I trust anyone claiming to be a doctor, or even someone who actually is a doctor.I guess it's a waste of time to also point out, despite your comment that "you trust the medical profession enough to trust what they say when they say they need respirators" that the information I linked to was all FROM medical professionals and that it is a currently evolving early swing in the opinion of the healthcare community.
Uh, well, then why'd you post it? And why are you now arguing it? It sounds to me like you want to have it both ways - put it out there and squash debate over it.Again, the whole point wasn't to argue any of this,
I broadly agree with your skepticism about how much of this effort is useful and worthwhile. However, I didn't always think that.but only to say that every company out there that currently has no need or demand for the products they normally make doesn't need to be making ventilators. We're going to end up with a billion ventilators that are useless because they are not needed.
The only reason there is a rush to make ventilators today is because most governments didn't order them years ago ahead of the next pandemic where they may be needed. The Trump GOP got the report from Obama's pandemic office before disbanding it two years ago saying that the US government was 740k respirators short of what it could potentially need for the next SARS or Spanish flu. If Trump had started working on that back then, the USA could easily have been 100k ventilators ahead of where it is today, which would have extended the amount of time before hospitals needed to start sharing them between patients by several weeks if not avoid it altogether, possibly long enough for the situation to stabilize and not require panic-buying.Even factoring in the needs of other countries, it would be overkill for ALL these companies that are gearing up to create ventilators, to ALL being doing it. Once one or two of them get going, in addition to the companies that normally make them, I think there will be more than enough for the cases that actually might require them.
