Are you medically trained in the use of a ventilator? If not, I don't see how you could make that judgment either.
But if you're going to claim the contrary, I take it that you have a wealth of experience administering ventilation.
For the record, I've worked in fields tangential to medicine, including lab research for FDA trials and health tech. I may not be qualified to operate a ventilator, but I'm experienced enough to understand the technical skill gap between a non-invasive procedure and an invasive one. And ventilation falls into the latter category.
