Isekhethi ye-ventilator iyisisetshenziswa sezokwelapha esixhuma isiguli emshinini womshini wokungenisa umoya, ovumela ukulethwa komoyampilo kanye nokususwa kwe-carbon dioxide.Iqukethe izingxenye ezihlukahlukene, okuhlanganisa amashubhu okuphefumula, izixhumi, nezihlungi, eziqinisekisa ukulethwa okuphephile nokusebenza kahle komoya emaphashini esiguli.Amashubhu ngokuvamile enziwe ngezinto zepulasitiki ezingasindi, eziguquguqukayo futhi eza ngosayizi abahlukene ukuze kuhlaliswe iziguli ezineminyaka yobudala nobukhulu obuhlukahlukene.Izixhumi zisiza ukuvikela amashubhu endaweni futhi zivikele noma yikuphi ukuvuza.Izihlungi zibalulekile ukuze kukhishwe noma yikuphi ukungcola noma amagciwane emoyeni, okunciphisa ingozi yokutheleleka.Amasekhethi okungenisa umoya asetshenziswa kakhulu ezibhedlela, emitholampilo, nasezindlini eziphuthumayo ezigulini ezinenkinga yokuphefumula ngenxa yezifo ezinzima noma ukulimala.
