Perhaps a more "low hanging fruit" solution for this problem space would be better procedures for helping people recover.

Doctors routinely prescribe antibiotics. I never had any of them tell me to eat yogurt afterwards to repair what they do to your gut biome. I learned that elsewhere.

No doctor ever told me I needed to taper off of steroids. I learned that from a friend.

There are a lot of ways modern follow-up care for medicine seems to be pretty bad and this is probably a much easier thing to improve upon than innovating on intubation tubes (which I'm not trying to discourage -- I see no reason we can't do both).
