Ventilator made from car parts

If it lasts for the duration of time the patients need it - the alternative being that 8 of them die anyway - is that not a good thing?

He has a PhD in respiratory medicine - I would trust his judgement on this, unless you are similarly qualified? (Check the tweet out, it links to it - I agree re: Daily Mail)

I’m sure it lasts the first 8 patients. Maybe not the next 8.  And I’d like more than the trite factoids to be presented by the daily mail which as a distinct reputation of spouting utter bullshit and distorting reality.

I’ll take a second opinion thanks. I can get one if I need it easily enough...

noname4me:
I just wanted to underline the severity of the situation:

The government is pushing through device approvals at the moment such that a lot of the required safety documentation and testing is being curtailed - this only happens if there is a dire need.

Yes, normally approvals take a long time, and have a necessarily rigorous V&V cycle.  They are also produced by companies which have the approvals in place to produce such devices.

The ventilator group - I don't know for certain if it actually has such certification, although the automotive industry is similarly well controlled.

It really in unprecedented, the way that everyone is working to a single aim to get these designed and produced in the shortest possible time.  Don't know if I'll ever see it again in my lifetime (hopefully not).

I still remember the look in my grandmothers eyes when they brought her back the second time from cardiac arrest while she was dying from cancer. It was a cross between sheer terror and annoyance that she had to suffer longer. Fortunately the third time didn’t work the day after and she passed away without hours of intense suffering.

What are you talking about?! Are you seriously suggesting that dying of Covid is a painless and peaceful exit? Are you suggesting that Covid is the same situation as terminal cancer? I'm talking about people who stand a chance of making a nearly full recovery with treatment vs virtually certain death without treatment. Would you *seriously* not try an un-approved but apparently functional ventilator on someone who was virtually guaranteed to die without it? Holy hell, I certainly hope if I end up in that position that I've got a doctor who is less concerned about consent and more willing to try anything they have at their disposal to save me. If it ends up killing me, well at least they tried, the alternative of dying by drowning slowly in my own juices does not sound like an improvement. A lack of approval does not automatically mean something is dangerous or ineffective.

I'm honestly baffled that someone would even suggest it's better to throw our hands up and let who knows how many people die because we know we can't get a sufficient number of certified machines. That's just... wow.  :o

bd139:
My point is it’s a hell of a lot more complicated than “saving lives” and people “living happily ever after” and throwing new untested technology into the mix can have a net negative on quality of life outcomes. Your point disregards nearly all of the complex matters and the probabilistic outcomes of forced ventilation.
