Izizathu Zeentlobo ezahlukeneyo zokuThukisa

Ukutshitshiswa kukungabikho koxinzelelo lweGazi

Kwinkalo yonyango - ngokukodwa iinkonzo zonyango zengxamiseko - ukutshitshiswa kunentsingiselo emithathu: ingaba ukukhutshwa kombane, isimo sengqondo okanye imeko esongela ubomi. Ngeenjongo zeli nqaku, siya kugxila kwizinto ezinokukubulala.

Ingxaki Ukuzalisa amaCapeillaries

Kungakhathaliseki uhlobo lokutshatyalaliswa, konke kunokufanayo: ukutshiswa kukuphazamisa amandla omzimba wokufumana igazi kuzo zonke iifom. Ukuze ulahleke ngokwaneleyo (ukufumana ngegazi) izicubu zomzimba, kufuneka kube negazi elaneleyo eliqhutywe kwi-system evaliweyo (imithanjeni yegazi, kuquka i-capillaries) enegunya elaneleyo (ukunyanzelela) ukunyusa imifuno encinci yegazi ebomvu enye ifayile iibhedi ze-capillary.

Kwintliziyo yakhe, ukutshatyalaliswa kukungabikho kwengcinezelo yegazi efanelekileyo.

Uxinzelelo lwegazi lweNgcinci

Ukutshatyalaliswa kunobangela obuninzi kwaye kwizigaba ezizayo kuya kubangela ukunciphisa uxinzelelo lwegazi. Xa umzimba unako ukugcina uxinzelelo lwegazi njengoko ukutshitshiswa kukhula, kwaziwa ngokuba yinto yokuxhatshazwa . Xa uxinzelelo lwegazi luqala ukuwa, luba ngumsindo wokungaxhaswanga . Ukuxhatshazwa okungahlawulwanga yimeko enzima engakwazi ukubulala, ingakumbi ukuba ingaphathwa .

Ukugcina uxinzelelo lwegazi ngumsebenzi wenkqubo ye-cardiovascular system, eneengxenye ezintathu ezihlukeneyo:

1. Fluid (igazi)
2. Iinqanawa zeempahla (iirrire kunye nemifuno)
3. Ipompo (intliziyo)

Kukho iintlobo ezine zokutshatyalaliswa kwezokwelapha, ezivela ekusilelweni kwesinye sezigaba ezintathu zesimo senhliziyo:

Hypovolemic

Ukutshatyalaliswa kwe-Hypovolemic kuvela ngenxa yokungabikho kwamanzi egazini. Iinqanawa zisenokuba zihambelane kwaye ipompo isebenza, kodwa i-fluid iphantsi.

Ukutshatyalaliswa kwe-Hypovolemic kungenziwa ngokuphuma ngegazi ngokuthe ngqo (ukutshatyalaliswa kwamanzi) okanye kwezinye ilahleko zombane. Ukudakalisa isidumbu kuyingxaki eqhelekileyo ye-hypovolemia, njengokuba i-sepsis (eyabangela ukutshatyalaliswa kokuphazamiseka).

Ukusasazwa

Ukutshatyalaliswa kokuphazamiseka okuvela kwisitya (imithanjeni yegazi) yokwandisa kakhulu kumlinganiselo wetsholongwane kwinkqubo. Isixa segazi kwinkqubo sinokuba siphantsi okanye siqhelekile, kodwa imithwalo yegazi yandisa kakhulu kakhulu ukugcina uxinzelelo olwaneleyo.

Ukutshatyalaliswa ngokubanzi kubangelwa kwiinqanawa ezixubileyo ngenxa yesiphumo sokunxibelelana kunye nengqondo (ukutshatyalaliswa kwe-neurogenic kwintlungu yomgogodla, umzekelo) okanye ukukhululwa kweembamamines ( ukutshatyalaliswa kwe-anaphylactic ).

Cardiogenic

Ukutshatyalaliswa kwe-cardiogenic kuyo yonke ipompo. Xa intliziyo iphela, njengentliziyo, ukuphazamiseka kwemizimba yiphumo.

Ukutshatyalaliswa kwentliziyo kwintliziyo ngumzekelo wokutshatyalaliswa kwemizimba. Ukungaphumeleli kwintliziyo yintliziyo kukubuyisela kwegazi emzimbeni okanye kumaphaphu ngenxa yecala elinye lentliziyo elonakaliswe kwi-heart attack. Inxalenye entle yentliziyo iphepha ngejubane ngokupheleleyo ngelixa uhlangothi olungonakaliyo alukwazi ukuqhubeka kwaye uxinzelelo lwegazi luyabangela ngenxa yoko.

Ukuthintela

Ukuxhatshazwa okuvakalayo ngumzekelo okhethekileyo. Oku kwenzeka xa ukugeleza kwegazi kuvaliwe ngumbutho ongaphandle.

Enye yemimiselo eqhelekileyo yokuphazamiseka okuphazamisayo ivela kwi- pneumothorax yokuxhatshazwa (ebizwa nangokuthi umphunga owenziwe). Umoya uqokelela kwisifuba ngaphandle kwemiphunga uze ufake uxinzelelo entliziyweni nakwezinye iinqanawa. Njengoko uxinzelelo lukhula, intliziyo ayinako ukupompa ngokwaneleyo kwaye ukuhamba kwegazi kunqatshelwe ngeempahla ezityunyiwe.

Omnye umzekelo oqhelekileyo wokutshitshiswa kokuphazamiseka kuvela kwi-ticonade ye-pericardial. Ingxowa ejikeleze intliziyo (i-pericardium) igaxa igazi phakathi kwayo nentliziyo ngaphakathi kwayo. Igazi elixakekile liqala ukubeka uxinzelelo entliziyweni kwaye lilukhuni kanzima ngokwaneleyo ukuhamba kwegazi.

Iintlobo zeeNtshonkco

Ezinye iintlobo zokutshatyalaliswa zidibanisa ezimbini okanye ngaphezulu kweentlobo ezingentla. Ukutshitshiswa kweSeptic yintsholongwane engagqithisi nje ukuphelelwa yinkcaso (i-hypovolemic) kodwa kunye nokukhutshwa kwesitya (ukusasazwa).

I-Trauma kwisifuba ihlala ingabangeli kuphela uxhaso lwe-pneumothorax (ukuphazamiseka) kodwa kunye nokuphaphazeka okukhulu (i-hypovolemic okanye, ukuba ukhetha ukuchaneka ngokukodwa, ukutshatyalaliswa okukhulu).

Hypoperfusion

I-Hypoperfusion iyona gama eliqhelekileyo lonyango abathi abanye ababoneleli benonophelo bezempilo basebenzise ukwahlula imeko yonyango yokutshatyalaliswa kwimeko yesimo sengqondo. I-Hypoperfusion ibhekisela ekuhlaleni kwegazi lokutshatyalaliswa kwezokwelapha.
