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 ndi kuyang'anira kupuma kwawo.Pali mitundu ingapo ya maulendo opumira a anesthesia, kuphatikizapo: Maulendo opumira (Maulendo otsekedwa): M'maderawa, mpweya wotuluka mpweya umapumira 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 ya unidirectional, ndi chigoba cha anesthesia kapena endotracheal chubu. Mipweya yatsopano imaperekedwa kwa wodwalayo ndi mpweya wambiri wa okosijeni, ndipo mpweya wotuluka umatulutsidwa kumalo ozungulira.Mapleson kupuma machitidwe: Mapleson machitidwe 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 zopumira 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 woyendetsedwa bwino komanso wogwira ntchito kwa wodwalayo, komanso kuchepetsa kupuma kwa carbon dioxide.Kusankhidwa kwa dera loyenera la kupuma kwa anesthesia kumadalira zinthu zosiyanasiyana, kuphatikizapo msinkhu wa wodwalayo, kulemera kwake, chikhalidwe chachipatala, ndi mtundu wa opaleshoni. Othandizira opaleshoni amalingalira mosamala zinthu izi kuti atsimikizire kuti mpweya wabwino ndi kusinthana kwa mpweya pa nthawi ya anesthesia.
