* If the patient receives less than the indicated lower treatment threshold, a case audit is to be undertaken. For these disorders, too few treatments may be unlikely to have sufficient therapeutic effect and potentially waste resources. Reasons for early termination of HBO therapy may include: death; misdiagnosis; non-compliance; deterioration, or failure to perceive improvement.

** For patients treated more than three days after clinical plateau.
