Highly skilled professionals also bled everyone a few centuries ago, a piece of paper does not equate truth. There are many doctors that now refuse to put anyone on these death machines.
Death machines - here we go.
I can tell you categorically the decision to use mechanical ventilation is not taken lightly, and usually in conjunction with family consent.
For the most part, patients requiring ventilation, if not placed on ventilation, will usually die.
One final intervention after ventilation is ecmo.
For those requiring ecmo, and not receiving it, rapid onset of death is an absolute certainty.
Both interventions are high risk and fraught with complications, but to call ventilators death machines is absurd.
