Abstract
The present invention provides a high-frequency oscillation artificial respiration apparatus that includes an inhale gas introducer that supplies an inhale gas containing oxygen to a patient and 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, an exhaust path that exhausts an exhale gas containing carbon dioxide exhaled from the patient, into the atmosphere, and an auxiliary inhale gas supply are also provided. The patient side path includes a branching pipe that branches a flow from the inhale gas introducer to the exhaust path side and the patient side and an intrachea insert tube that is connected to the patient side end of the branching pipe can be inserted through a mouth into the trachea of the patient.
