PCT No. PCT/JP85/00646 Sec. 371 Date Jul. 14, 1986 Sec. 102(e) Date Jul. 14, 1986 PCT Filed Nov. 21, 1985 PCT Pub. No. WO86/03128 PCT Pub. Date Jun. 5, 1986.A high-efficiency and compact high-frequency artificial respirator is disclosed. A patient circuit (1) of the artificial respirator is supplied with a respiration gas from a respiration gas supply source (6), and an oscillation generator (2) imparts high-frequency oscillation to the respiration gas thereby supplied. The patient circuit (1) has at one thereof a chamber defined by a vessel (12d) or a serpentine passage (31). A positive pressure is exerted on the chamber as a result of the gas being injected from nozzles (12e, 32).
