Starting a company is not fun for most engineers. Way more fun to get paid (a smaller amount, but way above "average") to hack at a company that has already found product-market fit. Replit doesn't have a Facebook-size audience, but it's still millions of people who you can reach with your work.
I'm impressed. Maybe those guys in Italy who 3d printed the valves can 3d print some of these components. I'm guessing the doctors there would be willing to try anything at this point.
Seems like this can be produced much faster on a CNC. 3D printing of large parts is extremely slow.
That said, I'm not even sure this is useful at all in practice, since I'm not a doctor. This needs to work on an intubated patient, and be able to maintain a sanitary environment, neither of which it'll probably be able to do to the extent required by health and safety regulations. But I'd love to be proven wrong by someone more knowledgeable in this case.
The other issue is that an ambu-bag doesn't work the same way a ventilator does, and can't provide the functionality that a critically ill respiratory patient would need. It can shove air into the lungs, but it can't manage pressures during the other phases of ventilation (which are equally, or even more, important).

Can you please elaborate on this? What pressures and what phases are involved?
The author explicitly calls for help and input from people to make it more functional and easier to built. Maybe your concerns can be addressable and they would be helpful.
In Italy doctors have to pick who to connect ventilators as they don't have enough number of them. This thing has the potential to save at least 1 more patient if not thousands.
It's a physical limitation of the bag style ventilation, it's not something you could design around by squeezing the bag differently.
For instance, the amount of "back pressure" during exhalation is important when managing ARDS patients. The ambu-bag can only exert pressure when it is being actively squeezed, and you can only squeeze it so far.
> In Italy doctors have to pick who to connect ventilators
I've read that this was exaggerated by the media. A doctor said that they _may at some point have to_ pick whom to treat, which the press has interpreted as them writing death warrants to those over 80.

I totally agree with you... but in the case where there are no respirators available at all, I'd rather have a 10% chance of secondary infection or contamination than just die.
I don't see a device like this as being a replacement for a $50k computer controlled machine, but as a stopgap in desperate emergencies.

But what if that 10% requires much more and longer medical care, doctors attention etc, such that someone else dies because they didn’t get treatment? I’m not saying it definitely is, but presumably the tradeoffs from a medical perspective are about more than about one personal perspective (which of course is a rational perspective)
Honestly I'd like to see a 1 month quarantine, with the US government guaranteeing the wages of everyone in the workforce for that time. Something like 100% up to 50k/year, 75% of 50-100k, and cap it there. It would cost a few hundred billion dollars but it would keep the "I have to work or be homeless" people from being homeless and allow them to actually stay home for that time.
Should cars prevent people from running red lights? There are a few unusual circumstances when this is something you want to do intentionally and knowing the risks.

That made me chuckle. I cringe at exaggerated, buzz-wordy, vague sales-copy as much as the other person, but isn't it shown to work (by Apple et al)? I'd be interested if you or anyone else have examples of to-the-point landing pages / sales-copy with zero exaggeration and gimmicks.
I liked the WhatsApp's back in the day [0], but they had a lot going for them and didn't need any extraordinary claims. MissiveApp [1] is another one that feels comfortable, to me.
For those of us not in that situation it's a lot harder, especially if you want to work now so you don't have to work later and can retire asap.
