ABSTRACT:
A gas administering method for administering gas to an airway of a patient having a nasal vestibule and for use with a gas administering apparatus comprises a primary gas source that is operable to provide gas and a nasal vestibular portion arranged so as to receive the gas from the primary gas source. Further, the nasal vestibular portion is capable of releasing the primary gas into the nasal vestibule. The method comprises inserting the nasal vestibular portion into the nasal vestibule, forming a seal between the nasal vestibular portion and an inner surface of the nasal vestibule, administering an amount of a gas from the primary gas source at a constant flow rate into the nasal vestibule via the nasal vestibular portion, and administering an anesthetic to the patient. The anesthetic induces depression of a portion of the nervous system of the patient. Furthermore, the seal promotes airway pressure buildup that is sufficient to prevent obstruction of the airway during depression of at least a portion of the nervous system and prevents escape of the gas from between the nasal vestibule and the nasal vestibular portion.
