Cyanosis ndeyebhuruu coloration yeganda uye mucous membranes. Inogona kukanganisa nharaunda (senge minwe kana kumeso) kana kukanganisa muviri wese. Izvo zvinokonzeresa zvakasiyana uye zvinosanganisira kunyanya kusanzwisisika kwemoyo, chirwere chekufema kana kuratidzwa nechando.

Cyanosis ndeye bhuruu coloration yeganda uye mucous membranes kana ropa riine shoma hemoglobin yakasungwa kune oxygen. Mune mamwe mazwi, tinotaura nezve cyanosis apo capillary ropa rine kana 5g yeiyo yakaderedzwa hemoglobin (ndiko kuti haina kugadziriswa kune oxygen) pa100ml.

Rangarira kuti hemoglobin ndiyo chikamu chemasero matsvuku eropa (anonziwo masero matsvuku eropa) anotakura oxygen. Chiyero chayo chinosiyana muvarume, vakadzi nevana.

Kana paine oxygen shoma muropa, inotora pane yakasviba tsvuku. Uye kana iyo midziyo yese (yemuviri wese kana yenharaunda yemuviri) iine ropa risina mweya, rinopa ganda iro bhuruu maitiro ecyanosis.

Zviratidzo zvinogona kusanganiswa necyanosis, zvinoenderana nezviri kukonzeresa. Semuenzaniso, kunetseka kufema, kurwadziwa pachipfuva, kupisa, kutadza kwemoyo kana kuneta kwakawanda.

Cyanosis inogona kungogumira kuchikamu chimwe chete chemuviri, senge miromo, kumeso, kumagumo (zvigunwe nezvigunwe), makumbo, maoko… kana zvinogona kukanganisa zvachose. Isu tinosiyanisa muchokwadi:

• Central cyanosis (kana generalized cyanosis), izvo zvinoratidza kuderera oxygenation ropa arterial;
• uye peripheral cyanosis iyo iri nekuda kwekuderedzwa kweropa kuyerera. Inowanzobata minwe nezvigunwe.

Muzviitiko zvese, cyanosis inofanira kungwarira uye zvinodikanwa kuti ubvunze chiremba anogona kugadzirisa uye kupa kurapwa.

Kune zvakawanda zvinhu zvinokonzera cyanosis. Izvi zvinosanganisira:

• kusvibiswa nechando;
• Chirwere chaRaynaud, kureva chirwere chekupararira. Iyo yakakanganiswa nzvimbo yemuviri inoshanduka kuva chena uye inotonhora, dzimwe nguva isati yashanduka bhuruu;
• kukanganiswa kwenzvimbo kwekutenderera, senge thrombosis (kureva kuvapo kwechiganda - kana thrombus - inoumba mutsinga yeropa uye inoitadzisa);
• kushungurudzika kwemapapu, sekukanganisa kufema kwekufema, pulmonary embolism, edema mumapapu, hematosis kusagadzikana (zvinoreva kuchinjana kwegesi kunoitika mumapapu uye kunotendera ropa rakapfuma mucarbon dioxide kushandurwa muropa rine oxygen);
• myocardial infarction;
• kusungwa kwemoyo;
• moyo wekuzvarwa nawo kana kusagadzikana kwevascular, izvi zvinonzi chirwere cheropa rebhuruu;
• kubuda ropa kwakanyanya;
• kutenderera kweropa kwakashata;
• kupererwa neropa;
• chepfu (semuenzaniso cyanide);
• kana zvimwe zvirwere zvehematological.

Cyanosis chiratidzo chinoda kubvunza kwachiremba. Kana chiratidzo chisina kutarisirwa, matambudziko mazhinji anogona kuitika (zvinoenderana nekwakatangira cyanosis nenzvimbo yayo). Ngatitaurei semuenzaniso:

• polycythemia, ndiko kuti kujairika mukugadzirwa kwemasero matsvuku eropa. Muchiitiko ichi, chikamu chemasero matsvuku eropa chinoenderana nehuwandu hweropa hwakawanda;
• hippocratism yedhijitari, ndiko kuti kushanduka kwezvipikiri zvinove zvinoputika (ona kuti Hippocrates akazvitsanangura kekutanga);
• kana kunyangwe kusagadzikana kana syncope.

Kurapa kwecyanosis kunoenderana nezviri kukonzeresa. Ngatitaurei semuenzaniso:

• kuvhiya (kuberekwa kwemoyo kuremara);
• oxygenation (matambudziko ekufema);
• kutora mishonga, yakadai se diuretics (kusungwa kwemoyo);
• kana iyo yakapusa yekupfeka inodziya (mune chiitiko chekuratidzwa nechando kana chirwere chaRaynaud).
