  1. To oxygenate excessively, that is, to give (a patient) too much oxygen therapy.

    If an attempt is made to use a low-flow oxygen device when a patient is in a labile period, the respiratory therapist will be unable to accurately adjust the oxygen flow to compensate for rapid changes in breathing pattern and may either overoxygenate or underoxygenate the patient.
