Abstract:
A high-frequency oscillation artificial respiration apparatus comprising:an inhale gas introducer that supplies an inhale gas containing oxygen to a patient, a patient side path that guides the inhale gas from the inhale gas introducer into the patient, an oscillating air pressure provider that applies an oscillating air pressure, having a higher frequency than a respiration frequency of the patient, to the inhale gas flowing through the patient side path, and an exhaust path that exhausts an exhale gas containing carbon dioxide exhaled from the patient, into the atmosphere, wherein the patient side path comprises a branching pipe that branches a flow from the inhale gas introducer to the exhaust path side and the patient side and an in-trachea insert tube which is connected to the patient side end of the branching pipe and can be inserted through a mouth into the trachea of the patient, the apparatus further comprising an auxiliary inhale gas supply that supplies an inhale gas to the vicinity of the lungs of the patient through a path different from the patient side path, the auxiliary inhale gas supply including an inhale gas supply including an inhale gas supply source and an auxiliary inhale gas supply path, which is different from the patient side path, that guides the inhale gas from the supply source into the lungs of the patient.
