Kuchuluka kwa okosijeni m'magazi ndi chimodzi mwazizindikiro zofunika za thanzi lathupi.Kuchuluka kwa okosijeni m'magazi a anthu abwinobwino athanzi kuyenera kusungidwa pakati pa 95% ndi 100%.Ngati ili pansi kuposa 90%, yalowa mumtundu wa hypoxia.% ndi hypoxia yoopsa, yomwe ingawononge kwambiri thupi ndikuyika moyo pachiswe.
Machulukidwe a okosijeni m'magazi ndi gawo lofunikira la thupi lomwe limawonetsa kupuma ndi kuzungulira kwa ntchito.Malinga ndi ziwerengero zosakwanira, zifukwa zambiri zofunsira mwadzidzidzi ndi madipatimenti opumira m'madipatimenti ofunikira m'zipatala zimagwirizana ndi mpweya wa magazi.Tonse tikudziwa kuti kutsika kwa okosijeni wocheperako sikungasiyanitsidwe ndi matenda opuma, koma sikuti zonse zimachepa m'magazi a oxygen omwe amayamba chifukwa cha matenda opuma.
Kodi zomwe zimayambitsa kuchepa kwa okosijeni m'magazi ndi chiyani?
1. Kaya kuthamanga pang'ono kwa okosijeni wokometsedwa ndikotsika kwambiri.Pamene mpweya wolowetsedwa uli wosakwanira, mpweya wa okosijeni ukhoza kuchepa.Kuphatikiza ndi mbiri yachipatala, wodwalayo ayenera kufunsidwa ngati adakhalapo kumapiri opitilira 3000m, kuwuluka kokwera, kukwera pambuyo pakuyenda pansi, komanso migodi yopanda mpweya wabwino.
2. Kaya pali kutsekereza kwa mpweya.M'pofunika kuganizira ngati pali obstructive hypoventilation chifukwa cha matenda monga mphumu, COPD, lilime muzu dontho, ndi yachilendo thupi kutsekereza kupuma katulutsidwe.
3. Kaya pali vuto la mpweya wabwino.M`pofunika kuganizira ngati wodwala chibayo kwambiri, chifuwa chachikulu, diffuse m`mapapo mwanga interstitial fibrosis, m`mapapo mwanga edema, m`mapapo mwanga embolism ndi matenda ena amene amakhudza mpweya ntchito.
4. Kodi Hb yomwe imanyamula mpweya m'magazi ndi yotani?Maonekedwe a zinthu zachilendo, monga poizoni wa CO, poizoni wa nitrite, ndi kuwonjezeka kwakukulu kwa hemoglobini yachilendo, sikuti kumakhudza kwambiri kayendedwe ka mpweya m'magazi, komanso kumakhudza kwambiri kutuluka kwa mpweya.
5. Kaya wodwala ali ndi colloid osmotic pressure yoyenera ndi kuchuluka kwa magazi.Kuthamanga koyenera kwa colloid osmotic ndi kuchuluka kwa magazi okwanira ndi chimodzi mwazinthu zofunika kwambiri kuti mpweya ukhale wabwino.
6. Kodi mtima wa wodwalayo umatuluka bwanji?Kusunga mpweya wabwino ku ziwalo kuyenera kuthandizidwa ndi kutulutsa kokwanira kwa mtima.
7. Minofu ndi limba microcirculation.Kukhoza kusunga mpweya wabwino kumakhudzananso ndi kagayidwe ka thupi.Pamene kagayidwe ka thupi kakakula kwambiri, mpweya wa okosijeni m'mitsempha umachepa kwambiri, ndipo magazi a venous amatsogolera ku hypoxia yoopsa pambuyo podutsa m'mapapo.
8. Kugwiritsa ntchito okosijeni m'magulu ozungulira.Maselo a minofu amatha kugwiritsa ntchito mpweya waulere, ndipo mpweya wophatikizidwa ndi Hb ungagwiritsidwe ntchito ndi minofu pamene watulutsidwa.Kusintha kwa pH, 2,3-DPG, ndi zina zotero kumakhudza kusokonezeka kwa mpweya kuchokera ku Hb.
9. Mphamvu ya kugunda.Kuchuluka kwa okosijeni kumayesedwa potengera kusintha kwa kuyamwa komwe kumachitika chifukwa cha kugunda kwa mtima, motero transducer iyenera kuyikidwa pamalo okhala ndi magazi othamanga.Zinthu zilizonse zomwe zimachepetsa kuthamanga kwa magazi, monga kukondoweza kuzizira, kusangalatsa kwa mitsempha yachifundo, odwala matenda a shuga ndi atherosulinosis, zidzachepetsa kuyeserera kwa chidacho.SpO2 silingadziwike ngakhale odwala ndi cardiopulmonary kulambalala ndi mtima kumangidwa.
10. Chinthu chomaliza, mutatha kusiya zonse zomwe zili pamwambazi, musaiwale kuti kuchepa kwa mpweya wa okosijeni kumatha chifukwa cha kulephera kwa zida.
Oximeter ndi chida chodziwika bwino chowunika kuchuluka kwa okosijeni m'magazi, omwe amatha kuyankha mwachangu momwe mpweya wa okosijeni m'magazi ulili m'thupi la wodwalayo, kumvetsetsa momwe thupi limagwirira ntchito, kuzindikira hypoxemia mwachangu, ndikuwongolera chitetezo cha odwala.
