Can't make a ventilator with a concentrator.

Although it would help you to have o2 to recover at home.

Never say never. With a little Trini ingenuity, somebody might pull one off with a palm frond, balloon, and a clothespin!

I've been following a lot of the efforts to design a low cost ventilator. Here is some light bathroom reading for anyone who is interested. Not rocket science but a matter of getting airway pressures and flows correct.

How Ventilators Work

Generating Positive Airway Pressure

Ventilator using Hospital Air Supply (Italian)

Tesla Video of their Ventilator

Bag Valve Mask Type Ventilators

MIT Version
Open Source Ventilator Project

Commercial Designs

Medtronic Ventilator Design Files that have been released...The license is not open source and only grants temporary use of data.

It's a generic vacuum at this point Franklin. Home Depot, Lowe's, Ventilators-R- Us. Get ear plugs.

Bag masks really work but they are intensive. Takes someone squeezing an awful lot.

It seems to me that this would be an excellent (inexpensive) alternative. Like Pete said, BVM really work well and are plentiful in hospitals.

It won't have the sensor systems that "proper" ventilators will have, but it seems workable (enough) with a little bit of setup for the individual patient to ensure you're getting the proper chest rise. It would be cheap, easy to build, and about a gazillion times better than being able to provide nothing for the patient.
