Primary Outcome Measures:

6-week cognitive sequelae

Secondary Outcome Measures:

Neurological examination
Depression, anxiety or post-traumatic stress syndrome
Vocational assessment
Patient self-reports of CO-related problems
We will follow patients at 6 months to categorize long-term outcomes, but the prime outcome follow-up period is 6 weeks after CO poisoning.

Estimated Enrollment:	200
Study Start Date:	April 2007
Estimated Study Completion Date:	May 2009

Detailed Description:

All patients presenting with acute carbon monoxide poisoning will receive one hyperbaric oxygen treatment (barring contraindications for hyperbaric oxygen therapy). After this treatment, eligible patients who provide consent will be randomly allocated to receive two sham sessions, or two additional hyperbaric oxygen sessions administered in a double-blind fashion.

Outcome measures will be administered at 6 weeks and 6 months.

Eligibility

Ages Eligible for Study:	18 Years to 79 Years
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Symptomatic CO poisoning (headache, nausea, vomiting, dizziness, fatigue, muscle aches, slowed mentation, confusion, or loss of consciousness).

Less than 24 hours from removal from the source of CO exposure and study enrollment.
Accidental poisoning

Exclusion Criteria:

Pregnancy
Age < 18 years or > 79 years
Complication during first hyperbaric oxygen session precluding subsequent hyperbaric oxygen.
Intentional CO poisoning
Unable to obtain informed consent
Moribund patient
Concomitant smoke inhalation with cyanide poisoning
Bleomycin use within two weeks of study enrollment
Intracardiac defibrillator that cannot be deactivated
Non-English speaking
Unlikely to return at 6 weeks
