Meihawl khu “charcoal smoke” hi medical term chuan Carbon monoxide poisoning/ Carbon monoxide tih a ni ber mai awm e.
Doctor-te chuan “charcoal smoke poisoning” tih an ziak ngai lem lo. Meihawl hian mihring chunga chhiatna a thlen azirin medical diagnosis bik an hmang thin.
Damdawi lam thiamna bulpui berah chuan: Carbon monoxide poisoning ICD-10 code: T58 Carbon monoxide hian nghawng tha lo ICD-11 code: NE61 Carbon monoxide nghawng tha lo a ngah hle.
Lab term chuan Carboxyhemoglobinemia tih a ni a. Thisenah hemoglobin nena inzawm CO a tam lutuk tihna a ni
A kalphung: CO + hemoglobin – Carboxyhemoglobin (COHb) tih a ni. Normal COHb = Meizial zu lo tan <2%, zu in lo tan <10%. Thihna thlen thei = a tlangpuiin >50-60% COHb a ni.
Doctor ten charcoal smoke exposure atana an hman thin damdawi dang: Medical Term hman hunah Inhalation injury Soot + heat a awm chuan thawkna kawngah meikhu + gas lum avanga lung chhiatna Hypoxic hypoxia A kalphung sawifiahna CO hian hemoglobin a block avangin tissue-ah oxygen a pe tlem a.

Meihawl khu vanga thi hmasa ber tunge hriat a harsa hle. Mihringin mei kan hman tan tirh atang khan charcoal/mei atanga carbon monoxide hian mihring a tihlum nasa tawh hle nia chhut a ni. Mahse, hei hi history-in a record dan chu a ni: Hmanlai Greek leh Roman hunlai, kum 2000 kal ta khan thihna a thlen tawh a ni. Greek leh Rom mite chuan meihawl chhem hian gas vanga thihna a thlen thei tih an hre tawh a, chu chu mi tihhlum nan an hmang thin. Kum tam tak liam ta atang tawh khan khuma mulai meihawl thuk nun avanga thi mi tam tak an awm thin. Napoleon-a surgeon Larrey chuan sipaite chu thingpui lumna hmanga tihlum carbon monoxide vanga thi an nih thu a ziak.
Kum 1857 Claude Bernard chuan CO hian hemoglobin atanga oxygen a paih chhuah avangin mi a tihlum thei tih a hrechhuak a, 1926 khan Warburg chuan CO hian thisen 35a4 chauh ni lovin cells direct-in tur [poison] a thlen bawk tih a hmuchhuak.
