Treatment for Cluster Headache
Oxygen therapy provides rapid vasoconstriction and sympathetic nervous system modulation, effectively reducing cerebral blood flow and alleviating acute cluster headache symptoms. High-flow 100% oxygen administered at 12-15 liters per minute via non-rebreather mask triggers a parasympathetic response that can terminate or significantly reduce the intensity and duration of cluster headache attacks by mitigating neurovascular inflammation and pain signaling.
