Kudos to him.

I am glad to hear about companies making ventilators. Mrs. is a Nurse at the local hospital. Masks and gowns are in such short supply that she is given one set for each potential infectious person she cares for. reusing masks is a danger to her and to other patients. Allegedly 3M is making over 1 million masks per day and another California company is making over 3 million a day. It would be really nice if some were actually delivered to hospitals for use. The hospital has been told everything is on back order by all the medical suppliers. Nurses have started turning in resignations and applying for other jobs because of the shortages. Which creates a strain for the remaining staff. Politicians keep saying fuzzy warm things about getting supplies for the medical workers, it would be nice if someone actually delivered instead of talking about it. I don't know where the logistics have failed, but it would be nice if one of them stepped in and actually did something to free them up.

I would be concerned about a brand new design for a ventilator, especially by someone who was not experienced with the design of ventilators. I'm sure there are all kind of subtleties in the design and operation of a ventilator and it would take quite a bit of testing to work it all out before you were willing to put it on a human. It seems to me that the best and safest approach is to take existing, proven designs and ramp up production.

Even then, I expect some problems with some of the units from manufacturing defects. When you push a production line you get problems.

If I had a loved one dying due to a lack of ventilators, I would rejoice to have someone step in with a new piece of equipment or to split one ventilator for two persons. We need to think how to make things work, not coming up with reasons why they might not work. I just watched a war film about Ford cranking out a B-24 bomber every 55 minutes during WWII. We need that mentality.

There are generally two kinds of ventilators....simpler designs like the one that Dyson came up with to "assist" with breathing by supplying air passively at low pressure and the more complicated computerized units that are designed for serious life support. A large percentage of the Covid-19 patients who are hospitalized supposedly can benefit from the simpler designs which are faster and easier to product. Dyson was actually in a good position to do this because they have extensive experience, research and IP around moving air efficiently with small devices. What they are doing should generally be extremely helpful in support of patients who just need some assistance and can be served by the simpler method. It does sound like their focus is primarily on the UK, however.

That distinction was not covered in the article posted. When I think of a ventilator, I think of intubating someone. From experience with a loved one who was intubated, I know that those ventilators are complex - and they're controlled by software.

The problem with any device that is used on humans is to make sure that it does not harm. That is, it would be tragic if the device caused death that would not have occurred without the device.

Yes, for full intubation, the "more complicated" computerized ventilator is required. You may notice that many of the folks posting on social media from their hospital beds are not intubated and are equipped with cannula at the nose that provides positive air pressure. Some may be on O2, but others are just getting air assist. There's a great need for both types.

I absolutely agree with the hope for "do no harm", however.

Could you point me to your source for this information? Particularly the first part?
Thanks

I am sorry Jim, but this sentence absolutely not correct. I am telling this as a professional, who is taking care of COVID 19 patients and other patients too.

I will accept and acknowledge I was incorrect. I was coming down with the damn thing at about the same time...

[Eduard Nemirovsky]

Jim, sorry to hear that. I wish you a full recovery.

Here's something that a few of you may find interesting.

So sorry to hear that Jim. Hang in there and be one of the many that recovers quickly.

Mike,

Perhaps they redesigned in effort to reduce the cost or time of creating such a unit. I certainly agree with you but when people are in desperate need what is ideal is going to become the adversary of what is possible.
