Nasal gas delivery system and method for use thereof

A gas administering method of administering gas to an airway of a patient having a nasal vestibule and for use with an anesthetic administering apparatus comprising an anesthetic gas source that is operable to provide an anesthetic, said method comprising:

• fastening a nasal vestibular portion to the anesthetic administering apparatus so as to receive the anesthetic gas from the anesthetic gas source, the nasal vestibular portion being capable of releasing the anesthetic gas into the nasal vestibule,
• inserting the nasal vestibular portion into the nasal vestibule;
• forming a seal between the nasal vestibular portion and a surface of the nasal vestibule;
• fastening a supplemental gas source to the anesthetic administering apparatus, the supplemental gas source being operable to provide a supplemental gas at a constant flow rate to the anesthetic administering apparatus;
• administering an amount of the supplemental gas from the supplemental gas source at a constant flow rate into the nasal vestibule, from the anesthetic administering apparatus, via the nasal vestibular portion, such that the seal promoters 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 anesthetic gas or the supplemental gas from between the nasal vestibule and the nasal vestibular portion;
• and
• administering, from the anesthetic gas source via the nasal vestibular portion, an amount of the anesthetic gas sufficient to induce depression of the at least a portion of the nervous system of the patient.

A gas administering system for administering gas to an airway of a patient having a mouth and a nasal vestibule, said gas administering system comprising:

• a gas source that is operable to provide gas at a constant flow rate;
• and
• a nasal vestibular portion arranged so as to receive the gas from said gas source, said nasal vestibular portion being capable of releasing the gas into the nasal vestibule, said nasal vestibular portion being shaped to from a seal between the nasal vestibular causes airway pressure buildup sufficient to prevent obstruction of the airway during depression of at least a portion of the nervous system,
• wherein the seal prevents escape of the gas from between the nasal vestibule and said nasal vestibular portion.

A gas administering method for administering gas to an airway of a patient having a face, a mouth, a nervous system and a nasal vestibule and for use with a gas administering apparatus comprising a gas source that is operable to provide gas and a nasal vestibular portion arranged so as to receive the gas from the gas source, the nasal vestibular portion being capable of releasing the gas into the nasal vestibule, said method comprising:

• inserting the nasal vestibular portion into the nasal vestibule;
• forming a seal between the nasal vestibular portion and a surface of the nasal vestibule;
• administering an amount of a gas from the gas source at a flow rate into the nasal vestibule via the nasal vestibular portion such that the seal causes 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;
• and
• administering an anesthetic to the patient to induce depression of the at least a portion of the nervous system of the patient.

A gas administering method for administering a gas to an airway of a patient having a nasal vestibular and for use with a gas administering apparatus comprising a gas source that is operable to provide gas at a flow rate and a nasal vestibular portion having a shape such that the nasal vestibular portion provides a force on a surface of the nasal vestibule, due to elasticity of the nasal vestibule, for retaining the nasal vestibular portion in the nasal vestibule, the nasal vestibular portion being arranged sa as to receive the gas from the gas source, the nasal vestibular portion being capable of releasing the gas, said method comprising:

• inserting the nasal vestibular portion into the nasal vestibule thereby forming a seal between the nasal vestibular portion and a surface of the nasal vestibule;
• administering an amount of a gas at a flow rate into the nasal vestibule via the nasal vestibular portion such that the seal causes airway pressure buildup that is sufficient to prevent obstruction of the airway while under sedation and prevents escape of the gas between the nasal vestibule and the nasal vestibular portion;
• and
• administering an anesthetic to the patient to induce depression of at least a portion of the nervous system of the patient.

• and
• administering, from the anesthetic gas source via the nasal vestibular portion, an amount of the anesthetic gas sufficient to induce depression of the at least a portion of the nervous system of the patient.

• a nasal vestibular portion arranged so as to receive the gas from said gas source, said nasal vestibular portion being capable of releasing the gas into the nasal vestibule, said nasal vestibular portion being shaped to form a seal between the nasal vestibular portion and a surface of the nasal vestibule such that the gas released into the nasal vestibule causes airway pressure buildup sufficient to prevent obstruction of the airway during depression of at least a portion of the nervous system,
• wherein the seal prevents escape of the gas from between the nasal vestibule and said nasal vestibular portion.
