Abstract:
1. A method of easing the duration of pain experienced by a patient during a cluster headache comprising providing a high pressure source of substantially pure oxygen capable of accepting a pressure input of about 50 psi and of delivering a maximum flow rate of at least about 140 l/m, applying said high pressure source of substantially pure oxygen to said patient in a manner such that inhalation by said patient is substantially limited to inhalation of said substantially pure oxygen using a demand valve having a predetermined manual purge flow rate and a variable output flow rate to the user based on respiratory demands, inhaling said substantially pure oxygen in a manner so as to cause hyperventilation by said patient, and continuing said hyperventilation at least until said patient achieves respiratory alkalosis, hypocapnia hyperoxia and until said pain is terminated.
