Iisekethe zokuphefumla i-anesthesia yinxalenye ebalulekileyo yenkqubo yokuhambisa i-anesthesia. Zisetyenziselwa ukuhambisa umxube weegesi, kubandakanywa i-oxygen kunye ne-anesthetic agents, kwisigulane ngexesha lotyando okanye ezinye iinkqubo zonyango. Ezi zijikelezo ziqinisekisa i-ventilation yesigulane kwaye zibonelela ngeendlela zokubeka iliso kunye nokulawula isimo sabo sokuphefumula.Kukho iintlobo ezininzi zeesekethe zokuphefumula kwe-anesthesia, kuquka: Iisekethe zokuphefumula (Iisekethe ezivaliweyo): Kule mijikelezo, iigesi eziphumayo ziphefumlelwa ngokuyinxenye yisigulane. Ziquka i-CO2 i-absorbent canister, esusa i-carbon dioxide kwi-exhaled gases, kunye ne-reservoir bag eqokelela kwaye igcine okwethutyana iigesi eziphumayo ngaphambi kokuba zibuyiselwe kwisigulane. Iisekethe zokuphefumula zisebenza ngokufanelekileyo ekugcineni ukushisa kunye nomswakama kodwa zifuna ukubeka iliso kunye nokugcinwa rhoqo ukuze kuqinisekiswe ukusebenza ngokufanelekileyo.Ii-circuits ezingasebenziyo (iisekethe ezivulekileyo): Ezi zijikelezo azivumeli isigulane ukuba siphefumle iigesi zabo eziphumayo. Iigesi ezikhutshwayo zigxothwa kwindawo engqongileyo, zithintela ukuqokelelana kwekharbon diokside. Iisekethe ezingaphefumliyo ngokuqhelekileyo ziquka imitha yokuhamba kwegesi entsha, ityhubhu yokuphefumla, ivalve ye-unidirectional, kunye ne-anesthesia mask okanye i-endotracheal tube. Iigesi ezitsha zihanjiswa kwisigulane nge-concentration ephezulu ye-oksijeni, kwaye iigesi eziphumayo zixoshwa kwindawo. Ezi nkqubo ziyahluka ekucwangcisweni kwazo kwaye zenzelwe ukunyusa ukutshintshiselana kwegesi kunye nokunciphisa ukuphefumla kwakhona kwe-carbon dioxide.Iinkqubo zokuphefumla isangqa: Iinkqubo zesangqa, ezaziwa ngokuba ziinkqubo zokutsala isangqa, ziinkqubo zokuphefumla ezisetyenziswa ngokuqhelekileyo kwi-anesthesia yanamhlanje. Zibonisa i-CO2 yokufunxa i-absorbent, ityhubhu yokuphefumla, ivalve ye-unidirectional, kunye nebhegi yokuphefumla. Iinkqubo zesangqa zivumela ukuhanjiswa okulawulwayo kunye nokusebenza kakuhle kweegesi ezitsha kwisigulane, ngelixa kunciphisa ukuphefumla kwakhona kwe-carbon dioxide.Ukukhethwa kwesiphaluka esifanelekileyo sokuphefumula kwe-anesthesia kuxhomekeke kwizinto ezahlukeneyo, kubandakanywa iminyaka yesigulane, ubunzima, imeko yonyango, kunye nohlobo lwenkqubo yokuhlinzwa. Ababoneleli be-Anesthesia baqwalasela ngokucophelela le miba ukuze kuqinisekiswe umoya ophezulu kunye nokutshintshana kwegesi ngexesha lolawulo lwe-anesthesia.
