Hyperbaric Oxygen Therapy for Carbon Monoxide Poisoning
An emergency UHMS-approved indication. Hyperbaric oxygen rapidly clears carbon monoxide from the blood and may reduce delayed neurological injury.
Typical Protocol
How HBOT Helps
HBOT cuts the half-life of carboxyhemoglobin from hours on room air to roughly 20–30 minutes, and is thought to limit the inflammatory cascade behind delayed cognitive effects.
What to Know
Used emergently, especially with loss of consciousness, neurologic signs, pregnancy, or high CO levels. Time-critical — this is hospital/emergency care, not a wellness booking.

Before You Book — What to Verify
- Chamber type: approved indications need a clinical hard-shell chamber (2.0–3.0 ATA), not a mild soft-shell unit.
- Whether a hyperbaric-trained physician supervises treatment.
- Insurance coverage and pre-authorization for this indication.
- UHMS accreditation status of the facility.
- That the recommended pressure and session count match the protocol above.
Frequently Asked Questions
Is HBOT FDA/UHMS-approved for CO poisoning?
Yes. Carbon Monoxide Poisoning is one of the indications approved by the Undersea & Hyperbaric Medical Society, and hyperbaric oxygen therapy for it is generally eligible for insurance coverage when criteria are met.
What pressure and how many sessions does CO poisoning typically need?
Standard-of-care protocols typically run at 2.5–3.0 ATA for about 1–3 sessions (emergent). Your physician sets the exact protocol based on your case.
How does hyperbaric oxygen help with CO poisoning?
HBOT cuts the half-life of carboxyhemoglobin from hours on room air to roughly 20–30 minutes, and is thought to limit the inflammatory cascade behind delayed cognitive effects.
How many directory centers list CO poisoning?
107 centers in our directory report treating CO poisoning, of which 32 are UHMS-accredited. Always confirm directly with the center.
