oxygen therapy
Treatment for Cluster Headache
High-flow oxygen therapy for cluster headache involves inhaling 100% oxygen at 12-15 liters per minute through a non-rebreather mask, which induces rapid cerebral vasoconstriction and reduces regional blood flow in the hypothalamus and trigeminal system. The rapid onset of action (typically within 15 minutes) and minimal side effects make it a first-line abortive treatment by ameliorating neurovascular inflammation and reducing pain signal transmission.
