Summary:
Carbon monoxide (CO) poisoning is common and causes cognitive sequelae. Hyperbaric oxygen reduces cognitive sequelae, but which patients need hyperbaric oxygen is unclear.
What This Study Adds to the Field: HBO2 oxygen is indicated for patients with acute CO poisoning who are 36 years or older or have exposure intervals greater than or equal to 24 hours. In addition, subgroup analyses support that patients with loss of consciousness or higher carboxyhemoglobin levels warrant HBO2.
