> I expect a device like this to have an extensive array of sensors and a lot of extra hardware for constant self-monitoring. If the two lines of devices don't have exactly identical hardware, the differences need to be checked carefully. The lower tier device may be missing some capabilities because of that.

This argument came up in the topic of using ventilators for two patients. It came up again in the topic of using home-built devices.

Of course using untested or under-tested equipment is a last resort. In a situation where there are no alternatives and a patient is dying, we do use unapproved drugs under “compassionate use” with much less testing than is otherwise be necessary. Using hacks like this with only some minimum of clinical testing is similar.

I think all your concerns are addressed in the article. They say it’s a proof of concept that needs more validation, as you would expect.
