Amasekhethi okuphefumula kwe-anesthesia ayingxenye ebalulekile yesistimu yokulethwa kwe-anesthesia. Asetshenziselwa ukuletha ingxube yamagesi, okuhlanganisa umoya-mpilo kanye nama-anesthetic agents, esigulini ngesikhathi sokuhlinzwa noma ezinye izinqubo zezokwelapha. Lezi zifunda ziqinisekisa ukungena komoya wesiguli futhi zinikeza indlela yokuqapha nokulawula isimo sazo sokuphefumula.Kunezinhlobo eziningana zamasekhethi okuphefumula kwe-anesthesia, okuhlanganisa: Amasekhethi okuphefumula (Amasekhethi avaliwe): Kulezi zifunda, amagesi akhishwa umoya aphefumula kancane isiguli. Ahlanganisa i-CO2 absorbent canister, esusa i-carbon dioxide emagesini akhishwe umoya, kanye nesikhwama se-reservoir esiqoqa futhi sigcine okwesikhashana amagesi akhishwe ngaphambi kokuba abuyiselwe esigulini. Amasekhethi aphefumulayo asebenza kahle kakhulu ekugcineni ukushisa nomswakama kodwa adinga ukuqapha nokugcinwa njalo ukuze kuqinisekiswe ukusebenza kahle.Amasekhethi angaphefumuli kabusha (Amasekhethi avuliwe): Lezi zifunda azivumeli isiguli ukuthi siphefumule kabusha amagesi azo akhishwe umoya. Amagesi akhishwa umoya axoshwa endaweni ezungezile, avimbele ukunqwabelana kwe-carbon dioxide. Amasekhethi angaphefumuli kabusha ngokuvamile ahlanganisa imitha yokugeleza kwegesi entsha, ishubhu lokuphefumula, i-valve engaqondile, kanye nemaski yokubulala izinzwa noma ishubhu le-endotracheal. Amagesi amasha alethwa esigulini ngokuhlushwa kwe-oksijeni ephezulu, futhi amagesi aphefumulayo axoshwa endaweni ezungezile.Izinhlelo zokuphefumula ze-Mapleson: Izinhlelo ze-Mapleson zihlukaniswa ngezinhlobo ezahlukene, kuhlanganise nezinhlelo ze-Mapleson A, B, C, D, E, ne-F. Lawa masistimu ayahlukahluka ekucushweni kwawo futhi aklanyelwe ukuthuthukisa ukushintshaniswa kwegesi nokunciphisa ukuphefumula kabusha kwe-carbon dioxide.Izinhlelo zokuphefumula eziyindilinga: Amasistimu ayindilinga, aziwa nangokuthi amasistimu wokumunca isiyingi, ayizinhlelo zokuphefumula kabusha ezivame ukusetshenziswa emisebenzini yesimanje yokubulala izinzwa. Zifaka ithini elimunca i-CO2, ishubhu lokuphefumula, i-valve yendawo yonke, kanye nesikhwama sokuphefumula. Amasistimu wombuthano avumela ukulethwa kwamagesi amasha okulawulwayo futhi okuphumelelayo esigulini, kuyilapho futhi kunciphisa ukuphefumula kabusha kwe-carbon dioxide.Ukukhethwa kwesifunda esifanele sokuphefumula kwe-anesthesia kuncike ezintweni ezihlukahlukene, kuhlanganise neminyaka yesiguli, isisindo, isimo sezokwelapha, kanye nohlobo lwenqubo yokuhlinzwa. Abahlinzeki be-Anesthesia bacubungula ngokucophelela lezi zici ukuze baqinisekise ukungena kahle komoya kanye nokushintshaniswa kwegesi ngesikhathi sokuphathwa kwe-anesthesia.
