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 (Iijikelezo 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 kakuhle.Ii-circuits ezingasebenziyo (iisekethe ezivulekileyo): Ezi zijikelezo azivumeli isigulane ukuba siphinde siphefumle iigesi zabo eziphumayo.Iigesi ezikhutshwayo zikhutshwa kwindawo engqongileyo, zithintela ukuqokelelwa 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 uhlobo lwenkqubo yotyando.Ababoneleli be-Anesthesia baqwalasela ngokucokisekileyo le miba ukuze kuqinisekiswe umoya ococekileyo kunye nokutshintshwa kwegesi ngexesha lolawulo lwe-anesthesia.
