ʻO nā kaapuni hanu anesthesia he mea koʻikoʻi o ka ʻōnaehana hāʻawi anesthesia. Hoʻohana ʻia lākou e hāʻawi i ka hui ʻana o nā kinoea, e komo pū me ka oxygen a me nā mea anesthetic, i ka mea maʻi i ka wā o ke kaʻina hana a i ʻole nā kaʻina lāʻau lapaʻau ʻē aʻe. Hoʻomaopopo kēia mau kaapuni i ka ea o ka mea maʻi a hāʻawi i kahi ala no ka nānā ʻana a me ka mālama ʻana i ko lākou kūlana hanu. Aia kekahi mau ʻano o nā kaapuni hanu anesthesia, ʻo ia hoʻi: Rebreathing circuits (Closed circuits): I loko o kēia mau kaʻa, hoʻomaha ʻia nā kinoea exhaled e ka mea maʻi. Loaʻa iā lākou kahi pahu hoʻoheheʻe CO2, kahi e hoʻoneʻe ai i ke kalapona kalapona mai nā kinoea exhaled, a me kahi ʻeke waihona e hōʻiliʻili a mālama i nā kinoea exhaled no ka manawa ma mua o ka hoʻihoʻi ʻana i ka mea maʻi. ʻOi aku ka maikaʻi o nā kaapuni rebreathing i ka mālama ʻana i ka wela a me ka maʻamau akā pono ka nānā ʻana a me ka mālama mau ʻana e hōʻoia i ka hana pono. Hoʻokuʻu ʻia nā kinoea exhaled i loko o ke kaiapuni, e pale ana i ka hōʻiliʻili ʻana o ka carbon dioxide. ʻO nā kaapuni ʻole-rebreathing maʻamau, ʻo ia ka mika kahe o ke kinoea hou, ka paipu hanu, ka valve unidirectional, a me ka pale anesthesia a i ʻole ka paipu endotracheal. Hāʻawiʻia nā kinoea hou i ka mea maʻi me ka nui o ka oxygen, a hoʻokuʻuʻia nā kinoea exhaled i loko o ke kaiapuni.Mapleson breathing systems: Mapleson system is categorized in different types, including Mapleson A, B, C, D, E, and F systems. ʻOkoʻa kēia mau ʻōnaehana i kā lākou hoʻonohonoho ʻana a ua hoʻolālā ʻia no ka hoʻololi ʻana i ke kinoea a hōʻemi i ka hanu hou ʻana o ka carbon dioxide. Hāʻawi lākou i kahi pahu hoʻoheheʻe CO2, kahi pahu hanu, kahi pahu unidirectional, a me kahi ʻeke hanu. ʻO nā ʻōnaehana pōʻai e ʻae i ka hāʻawi ʻana i nā kinoea hou i ka mea maʻi, ʻoiai e hōʻemi ana i ka rebreathing o carbon dioxide. ʻO ke koho ʻana i ke kaapuni hanu anesthesia kūpono e pili ana i nā kumu like ʻole, me ka makahiki o ka mea maʻi, ke kaumaha, ke kūlana olakino, a me ke ʻano o ke kaʻina hana. E noʻonoʻo pono nā mea hoʻolako anesthesia i kēia mau mea e hōʻoia i ka maikaʻi o ka ventila a me ka hoʻololi kinoea i ka wā o ka hoʻokele anesthesia.
