Methods for easing the duration of pain experienced by patients during a cluster headache are disclosed including providing a high-pressure source of substantially pure oxygen, applying the oxygen to the patient so that inhalation by the patient is substantially limited to inhalation of the substantially pure oxygen, inhaling the substantially pure oxygen in order to cause hyperventilation by the patient, and continuing hyperventilation at least until the patient achieves respiratory alkalosis, hypocapnia hyperoxia, and until the pain is terminated. The method preferably includes using a demand valve having a predetermined manual purge flow rate and a variable output flow rate to the user based on respiratory demand.
La présente invention concerne un procédé permettant de diminuer la durée de la douleur ressentie par les patients lors dune algie vasculaire de la face consistant à apporter une source de haute pression doxygène sensiblement pur, à appliquer loxygène au patient de telle sorte que linhalation par le patient se limite sensiblement à linhalation de loxygène sensiblement pur, à inhaler loxygène sensiblement pur afin de provoquer une hyperventilation chez le patient, et à poursuivre lhyperventilation au moins jusquà ce que le patient atteigne une alcalose respiratoire, une hyperoxie-hypocapnie, et jusquà ce que la douleur disparaisse. Le procédé consiste de préférence à utiliser une soupape dadmission à la demande ayant un débit de purge manuelle prédéterminée et un débit de sortie vers lutilisateur variable basé sur la demande respiratoire.
