My apologies, that was meant in relation to covid specifically. But i can tell you, your brother must have been strong, many are ready to give up after a few weeks on vent, its often reported that when asked patients would take death over another multi week stint on a vent. Its not specified but im sure its not just the vent, its being treated like an experiment, getting poked, drugged, monitors / noise constantly popping off. unfortunately the icu environment is one of the least human. But again regardless, hats off to your brother, he was a strong willed mofo to go through that for that long.
