METHOD OF DEMAND VALVE OXYGEN THERAPY FOR RAPID ABORT OF CLUSTER HEADACHE

摘要

Methods for easing the duration of pain experienced by patients during acluster headacheare disclosed including providing a high-pressure source of substantially pureoxygen,applying the oxygen to the patient so that inhalation by the patient issubstantially limited toinhalation of the substantially pure oxygen, inhaling the substantially pureoxygen in orderto cause hyperventilation by the patient, and continuing hyperventilation atleast until thepatient achieves respiratory alkalosis, hypocapnia hyperoxia, and until thepain is terminated.The method preferably includes using a demand valve having a predeterminedmanual purgeflow rate and a variable output flow rate to the user based on respiratorydemand.
