^^^ Hear, hear!

Mixing terminology in healthcare is deadly. Not "can be", but IS deadly.

No one is making a fully functional, homemade ventilator. They are attempting to make respirators. A rather significant difference.

What Won posted appears to be a certainly viable....respirator, for a conscious and cooperating patient. See the smile and thumbs up?

Try strapping that thing on someone in distress, gasping for breaths. Or possibly even combative.

( here's a side assignment for everyone, take a look at how a toddler is restrained to acquire an x-ray image... then report back )

Those not in healthcare attempting to build an "open source ventilator" makes about as much sense as the Jiffy Lube guy does on an F1 Team.
