In brief: Depends

It depends on the reason why the patient was placed on the ventilator in the first place and how they respond.
Sometimes an abg is obtained only a few minutes after being placed on a ventilator (e.g. After an emergency intubation); often, an abg is not needed at all (e.g. Intubated for an elective procedure requiring general anesthesia).
