Are there indications for hyperbaric oxygen?

💡 Diagnose by carboxyhemoglobin (COHb) — pulse oximetry is unreliable and may read falsely normal. All suspected/confirmed cases get immediate high-flow 100% normobaric oxygen (non-rebreather mask) to shorten the COHb half-life; intubate and ventilate with 100% oxygen if comatose/hypoventilating. Remove from the source, supportive care, monitor for delayed neuropsychiatric sequelae.
