Maulendo opumira a anesthesia ndi gawo lofunikira la dongosolo loperekera opaleshoni.Amagwiritsidwa ntchito popereka mpweya wosakanikirana, kuphatikizapo mpweya ndi mankhwala opha ululu, kwa wodwala panthawi ya opaleshoni kapena njira zina zachipatala.Mabwalowa amaonetsetsa kuti wodwalayo akupuma mpweya wabwino ndipo amapereka njira yowunikira komanso kuyang'anira momwe akupuma.Pali mitundu ingapo ya maulendo opumira a anesthesia, kuphatikizapo: Mabwalo opumira (Mabwalo otsekedwa): M'maderawa, mpweya wotuluka mpweya umapuma pang'ono ndi wodwalayo.Amakhala ndi CO2 absorbent canister, yomwe imachotsa mpweya woipa kuchokera ku mpweya wotuluka, ndi thumba losungiramo madzi lomwe limasonkhanitsa ndikusunga kwakanthawi mpweya wotulutsa mpweya usanabwezedwe kwa wodwalayo.Mabwalo opumira amathanso kuteteza kutentha ndi chinyezi koma amafunikira kuyang'anitsitsa nthawi zonse ndi kukonzanso kuti zitsimikizidwe kuti zikugwira ntchito bwino.Magawo osapumira (Open circuits): Mabwalowa salola kuti wodwalayo apumenso mpweya wawo wotuluka.Mipweya yotulutsa mpweya imathamangitsidwa m'chilengedwe, kulepheretsa kudzikundikira kwa carbon dioxide.Mabwalo osapumira mpweya nthawi zambiri amakhala ndi mita yatsopano yoyendera mpweya, chubu chopumira, valavu yolowera, ndi chigoba cha anesthesia kapena chubu cha endotracheal.Mpweya watsopano umaperekedwa kwa wodwala wokhala ndi mpweya wambiri wa okosijeni, ndipo mpweya wotuluka umathamangitsidwa kumalo ozungulira.Mapulani a kupuma kwa Mapleson: Machitidwe a Mapleson amagawidwa m'magulu osiyanasiyana, kuphatikizapo Mapleson A, B, C, D, E, ndi F machitidwe.Machitidwewa amasiyana malinga ndi kachitidwe kawo ndipo amapangidwa kuti apititse patsogolo kusinthana kwa gasi ndi kuchepetsa kupuma kwa carbon dioxide.Njira zopuma zozungulira: Njira zozungulira, zomwe zimadziwikanso kuti zozungulira zozungulira, ndi machitidwe otsitsimula omwe amagwiritsidwa ntchito masiku ano opaleshoni ya anesthesia.Amakhala ndi canister ya CO2, chubu chopumira, valavu ya unidirectional, ndi thumba lopumira.Machitidwe ozungulira amalola kuti mpweya wabwino ukhale wolamulidwa komanso wothandiza kwa wodwalayo, komanso kuchepetsa kupuma kwa carbon dioxide.Kusankhidwa kwa dera loyenera kupuma kwa anesthesia kumadalira zinthu zosiyanasiyana, kuphatikizapo msinkhu wa wodwalayo, kulemera kwake, matenda, ndi mtundu wa opaleshoni.Othandizira opaleshoni amalingalira mosamala zinthu izi kuti atsimikizire kuti mpweya wabwino ndi kusinthana kwa mpweya pa nthawi ya anesthesia.
