Yes, it’s slightly nuanced and individual of course. Just like with more traditional drugs (oxygen is considered a drug) there are always pros, cons and risks to all of it especially when not used appropriately.So am I understanding correctly that physiologically people can tolerate lower sats, but doctors are now concerned about that because someone could panic and crash quickly? Can't their diligence to prevent that sometimes actually exacerbate that by aggressive oxygen use (thinking high FiO2 and ROS damage to lungs; plus I've read CPAP with PEEP can damage lungs)?
I personally have always tried (as I was taught in school & clinicals) to keep oxygen and peep to the minimum amount necessary to maintain a person with the least potential for harm. I have seen coworkers that didn’t attempt aggressive weaning out of either busyness or laziness though. If you need to be told by a doctor to wean then you are probably not doing your job. Every hospital I’ve worked at has vent and oxygen weaning protocols in place so you don’t have to wait on a doctor to do the best thing for the patients.
