Well you also need the personnel to operate them.
Wishful thinking. Source the part, manufacture and test them.
If the make some parts in 3d printing those parts will need to be validated, they are different from the actual design.
Assembly 2000/day...don't know.
These are medical device, no matter how simple they might be, still I guess you'd want to have them produced in a modern and safe way (and those certification process have a greater importance than the pure industrial assembly one)
Unlike a lot of people, I've been through this. Last year, my wife contracted pneumonia and it progressed into ARDS (Acute Respiratory Distress Syndrome), which is what is happening to critically ill COVID-19 patients. That required that she be in a medically induced coma and on a ventilator for 19 days. After the 19th day, she was transferred to a longterm acute care facility, where she was weaned off the ventilator over a two week period. It took her those two weeks to become fully conscious, and even then she suffered from
ICU delirium for another two weeks.
When you get ARDS, your lungs become hard and you can no longer breathe on your own. It takes a long time and a lot of drugs to get you well again. She spent a month in the hospital, a month in the long-term acute care facility, and a month in a rehab facility.
I found out later that her chances of survival were 10%. (She is diabetic, has high blood pressure, and has suffered from asthma her entire life - almost died from it several times.)
The doctors tried hard to get me to pull the plug. They told me my wife had very little chance of survival. One doctor told me at least five times, "If a healthy 18-year-old boy had what your wife has, he would have a 50% chance of survival." The message was quite clear. And they were telling the truth. But I held on, and she eventually recovered.
If she got COVID-19, I don't think she'd have a snowball's chance in hell of surviving, and I suspect the doctors if they were overwhelmed with patients, would pull the plug without my approval. That's the hard reality of something like this.
That's why we haven't left the house (except for a brief no-contact foray) since the middle of last week. We're not taking any chances because we know how brutal this can be. It took her ten months to fully recover and even now she has to take (self-administered) breathing treatments daily.
In order to properly operate a ventilator, you need to be a fully qualified respiratory technician under the supervision of a pulmonologist. You aren't going to produce those overnight. What's going to happen is that retired respiratory techs and pulmonologists will be pressed into service as well as students who are still learning and people who have left the hospital setting and moved into other lines of medical work. (If it gets to that point.) And hard decisions will have to be made about who lives and who dies. This is serious stuff. Deadly serious.
