Intensive Care provides organ support while a reversible process is treated. There is no benefit of intensive care in the context of an irreversible pathology.

For Intensive Care to work, you need both a reversible disease and a patient with the reserve to respond to treatment. Intensive Care is a burdomsome treatment. It is rare for patients to come out of it unscathed (either physically or psychologically). It is not “sleeping on a breathing machine” - at a cellular level, patients are running consecutive marathons.
