Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Cluster headache is a disorder marked by frequent attacks of short-lasting, severe, unilateral head pain with associated autonomic symptoms. It is the most severe head pain syndrome known. Currently, the two most common treatments for cluster headaches are inhaled oxygen and injectable sumatriptan. These treatments do not work for all cluster headache patients, and patients who smoke may eventually develop contraindication to triptans. New treatment options are needed. An alternative method of oxygen delivery (as opposed to continuous flow) uses a demand valve that is controlled by respiration rate, allowing increased oxygen flow in response to increased demand. This system may be more efficacious at stopping a cluster headache attack than the currently prescribed oxygen delivery system. This study will compare the effectiveness of oxygen delivered via demand valve versus continuous high flow oxygen via non-rebreather face mask in the acute treatment of a cluster headache attack. All patients will treat one cluster headache with each of the 2 treatment methods.
