Chii chinonzi hypoxia, chii chinokonzeresa uye kurapwa

Zvemukati

• Zviratidzo zvikuru
• Chii chinokonzera hypoxia
• Ndedzipi mhando
• Kurapwa kunoitwa sei
• Zvinogoneka sequelae
• Musiyano we hypoxia uye hypoxemia

Hypoxia mamiriro ezvinhu anoitika kana huwandu hweokisijeni hunotakurwa kuenda kumatishu emuviri husina kukwana, zvichikonzera zviratidzo zvakaita sekurwadziwa nemusoro, kukotsira, kutonhora ziya, kutsvuka neminwe uye muromo uye kunyange kupera simba. Shanduko iyi inogona kuitika nekuda kwechirwere chemoyo, chakadai seakakomba myocardial infarction, hosha dzemapapu, senge asthma uye acute lung edema, asi inogona zvakare kusimuka nekuda kweropa uye kukwirira kwakakwirira.

Kurapa kwehypoxia kunoenderana nechikonzero, kuomarara uye mamiriro ehutano hwemunhu, zvisinei, muzviitiko zvakawanda, inoumbwa nekutungamirwa kweoksijeni kuburikidza nemasiki kana neorotracheal intubation. Aya mamiriro anogona kukonzera sequelae mumuviri, saka kana zviratidzo zvikaonekwa, zvinokurudzirwa kufonera iyo SAMU ambulensi ku192 nekukasira.

Zviratidzo zvikuru

Zviratidzo zvehypoxia zvinosiyana kubva kune mumwe munhu kuenda kune mumwe, sezvo zvinoenderana nekuomarara kwekushayikwa kwe oxygenation mumatumbu emuviri, asi anogona kuve:

• Kurwadziwa nemusoro;
• Somnolence;
• Yakawedzera kurova kwemoyo;
• Kutonhora ziya;
• Kufema kwekufema;
• Dzungu;
• Kuvhiringidzika kwepfungwa;
• Kufenda;
• Purple minwe uye muromo, unonzi cyanosis;

Cyanosis inomuka nekuti tsinga dzeropa dziri kumucheto kwemuviri dzinonamira kutumira ropa rakawanda uye yakawanda okisijeni kunhengo huru dzemuviri uye nekuda kweizvozvo, kuwedzera kweropa kunoitikawo. Dzidza zvakawanda nezve cyanosis uye kuti inorongwa sei.

Nekudaro, hypoxia painowedzera, BP ichidzika uye munhu anogona kurasika njere, saka panotanga kuoneka zviratidzo zvekutanga, zvakakosha kufonera iyo SAMU ambulensi muna 192, nekukasira, kuitira kuti kurapwa kwekukurumidzira kuitwe.

Chii chinokonzera hypoxia

Hypoxia inoitika kana huwandu hweoxygen munyama husina kukwana uye izvi zvinogona kukonzerwa nezvikonzero zvakati wandei, sekufema kufema, asima, pulmonary emphysema, acute lung edema nemabayo, sezvo zvichikonzera kupinda kwe oxygen mumapapu kutadza. . Dzimwe shanduko dzemutsipa dzinokonzerwa nekushungurudzika kwemusoro dzinogona kukonzera hypoxia, sezvo ichikanganisa kufema mabasa.

Hemoglobin, irimo muropa, inoitisa kutakura okisijeni kunhengo dzemuviri uye yakaderera muvanhu vane chirwere chekushaya ropa, izvo zvinogona kukonzera hypoxia munyama dzomuviri, kunyangwe kufema kuchichengetwa. Chimwe chikonzero chehypoxia chingave kudhakwa nezvigadzirwa zvakadai secyanide, carbon dioxide uye psychoactive zvinodhaka.

Pamusoro pezvo, zvimwe zvirwere zvemwoyo, zvakadai seacute myocardial infarction, zvinokanganisa kutenderera kweropa nekudzivirira okisijeni kubva kuendeswa kumatumbu emuviri. Munzvimbo dzakakwirira kwazvo kana dzakadzika, huwandu hwe oxygen hwakadzikira kwazvo, saka kana munhu ari munzvimbo idzi, anogona zvakare kutambura ne hypoxia.

Ndedzipi mhando

Mhando dzehypoxia dzakabatana nechikonzero chekushayikwa kweoxygen mumuviri, inogona kuve:

• Kufuridzira hypoxia: mhedzisiro kubva pakuderera kwekuwanikwa kweoksijeni kumapapu, zvichikonzerwa nekusavapo kana kuderedzwa kwekufema, kungave nekuda kwechimwe chirwere kana nekuda kwekuvharika kwemhepo;
• Anemic hypoxia: inoitika kana huwandu hwehemoglobin muropa hwakadzika kwazvo, zvichitungamira kudzikira kweoksijeni inotakurwa muropa;
• Kutenderera hypoxia: inomuka mumamiriro ezvinhu umo kurasikirwa kweropa kunokonzeresa kuchinjanisa gasi mumapapu kuti isaitwe nemazvo, sekushaya moyo;
• Hypoxia yenhengo chaidzo: zvinoitika kana tsinga yeimwe nhengo ikavharika, ichidzivirira kufamba kweropa uye kudzikira huwandu hweoxygen munzvimbo iyi, semhedzisiro yeatherosclerosis, semuenzaniso.

Kune zvakare mhando yehypoxia inoenderana nekuzvarwa kwemoyo kusagadzikana, senge Fallot's tetralogy, iyo inoita kuti arteri isina kukwana isakwanise kutakura okisijeni kunhengo dzakakosha mumuviri, senge uropi, semuenzaniso. Ona zvimwe kuti kurapwa kweFallot's tetralogy kunoitwa sei.

Kurapwa kunoitwa sei

Iyo yekurapa kweiyo hypoxia inoenderana zvakanyanya nekutungamira kweoksijeni kuburikidza nemasiki, nasal catheters kana okisijeni matende, hunhu hwemhepo isingakuvadze mweya. Zvisinei, mumatambudziko akaipisisa, zvinokurudzirwa kuisa chubhu kuburikidza nemuromo kuendesa okisijeni yakananga kumapapu, anozivikanwa seorotracheal intubation.

Kana hypoxia ichikonzerwa nekushaya ropa, kuiswa kweoksijeni hakuzove nemhedzisiro inogutsa, nekuti kunyangwe kana huwandu hweoxygen mumuviri huchiwedzera, pane huwandu husina kukwana hwehemoglobin, isingakwanise kuisa oxygenese matukisi ese, saka zvakafanira ita kuwedzerwa ropa kuendesa yakawanda hemoglobin muropa. Dzidza zvakawanda nezve maitirwo eropa anoitwa.

Saizvozvo, kana chirwere chemwoyo chakakomba chokonzera hypoxia, kufamba kweropa kuchikundikana uye kungoona kufema hakuna kukwana, zvinodikanwa kugadzirisa matambudziko kutanga, sekuvhiya, semuenzaniso.

Zvinogoneka sequelae

Hypoxia inogona kukonzera sequelae kumuviri uye zvinoenderana nenguva iyo munhu anga asina kufema uye nguva iyo muviri wanga usina huwandu hweoxygen hunodiwa kuti uchengetedze mabasa ayo akakosha. Shanduko munzvimbo yepakati yetsinga inomiririra mhedzisiro huru yehypoxia, inotungamira mukukanganisa kufamba kwemuviri uye nekukanganisa zviitiko sekufamba, kutaura, kudya uye kuona.

Mune zvimwe zviitiko, kana hypoxia yakanyanyisa uye munhu asingakwanise kufema ega, zvinodikanwa kuti uite intubation, ndiko kuti, zvishandiso zvinofanirwa kuunzwa kubatsira maitiro ekufema, uye kazhinji, chiremba anoratidza kuti coma yakakonzerwa. Tarisa uone izvo zvinokonzereswa kufenda uye zvimwe zvinoratidza.

Musiyano we hypoxia uye hypoxemia

Dzimwe nguva hypoxia inovhiringidzika nezwi hypoxemia, zvisinei, ivo vanoreva kune akasiyana mamiriro. Hypoxemia inotsanangurwa seyakadzika kuwanda kweoxygen muropa, ndiko kuti, kana oxygen kugutisa, kuyerwa nenzira yekupomba oximetry, iri pamutengo wakaderera we90%, hypoxia inozivikanwa sekudzikiswa kweo oxygenation mumatumbu emuviri. . Kazhinji, zviratidzo zvakafanana, nekuti hypoxia inogona kuitika semhedzisiro yehypoxemia.
