The anesthesia process is not over when the patient leaves the OR - the patient is still under the medical supervision of the anesthesiologist until eligible for discharge. In post-anesthesia care, the patient is often still under the influence of anesthetic drugs which may cause unexpected things to happen.
Careful monitoring is necessary.
One of the key elements for a smooth recovery process is continuity of care, facilitated by continuity of data through the entire perioperative process, and seamless communication between the care personnel. Standardization of equipment and accessories in the anesthesia department helps ensure fast transfer of patients from one care area to another.
