Phakathi naleso sikhathi, ukumisa zokuphila kungaba ngenxa kwethonya iziphi izici zangaphandle. Ngokwesibonelo, ukwephula ngehlangothini elinye ndaba. Kulokhu ekutadisheni izimo sokufa komuntu Kwenziwa criminologists.

Izinhlobo ukufa ngesihluku ihlukaniswa ngokweminyaka izimfuneko ezithile. Ngokuyinhloko, izici sangaphandle umzimba angawodwa.

esigabeni

Ezingeni yemvelo, abantu bayafa ngezigaba ezintathu:

1. Esikhathini esigabeni sokuqala izici ezifihliwe noma ngenye esiphawulekayo noma okusithiyayo of isitho umsebenzi uqala, obhekene kwegazi nokuphefumula kwezimila. Ukusebenza kahle lwalezi nhlelo Nokho, ungami. It nje akwanele ukuhlangabezana isidingo samanzi emzimbeni ukuze umoya-mpilo.
2. In the isinyathelo sesibili iqala autoregulation. Ngokuhamba izinqubo zayo zangaphakathi ocushiwe, okuyinto ivala isikhala yokucindezela ukusebenza kwezitho. Kulesi simo, nezicubu imisipha iqala ukuncipha. Lokhu kuholela kwezimila anda. Kuvulwa esidlule izinsiza zangaphakathi umzimba.
3. Ngesikhathi sigaba lokugcina, sebefile. Kuleli zinga, inhliziyo eyeka ukushaywa ukuphefumula. ukufa Clinical kungathatha imizuzu engu-2 ihora. Konke kuzoncika ezintweni zangaphandle kanye nezinye. Phakathi nale nkathi esichithwa zakamuva-mpilo izinqolobane oxidative ukusabela phakathi emangqamuzaneni. Ngemva kwalokhu iqala ukuba ngivule izicubu emsipheni.

ukuphela uthi

Noma yiluphi uhlobo lokufa kwabantu siqeda esiteji ezithile. Ngokubambisana ingahlala kusuka imizuzu embalwa / amahora kuya ezinsukwini ezimbalwa. uthi terminal predagonalnaya esiteji, ngobuhlungu, eqinisweni aze abe sebefile. Lesi sakamuva samanje noma kunjalo, kungakhathaliseki ukuthi izinga ehushule ukusebenza kubalulekile imisebenzi umzimba. Kuleli zinga, kukhona ithuba Njengomzamo wokuvikela ukufa. Ngenxa yalesi le yokusiza umuntu ukuba aphefumule. Uma babengakholwa kwenziwe noma akuzange kuphumelele, impilo umzimba liyaphela.

Izinhlobo, izimpawu sokufa: isimo predagonalnoe

It kuhambisana kuphula umthetho we isimiso sezinzwa esiyinhloko, ekunciphiseni ingcindezi, yinye kwegazi. Isiguli sinelungelo ukuphazamiseka zokuphefumula. Kuba okungajwayelekile, engajulile, kungase ngiqinise. Ngenxa yokuntuleka ukupholisa emaphashini kwenzeka ukushoda umoya-mpilo emzimbeni. Ngakho njengoba main exchange izinqubo kukhona ukusabela namachibi. isimo besikhatsi predagonalnogo kuyahlukahluka. Kungase kube lingekho ngokuphelele. Lokhu kwenzeka, isibonelo, by mechanical ezinzima isifo senhliziyo. Predagonalnoe ingahlala isikhathi eside ngokwanele. Ngokwesibonelo, uma umzimba ngandlela-thile isinxephezelo attenuation of imisebenzi ebalulekile.

umunyu

Kutama yomzimba lapho izinhlelo imisebenzi abacindezelekile kubalulekile ukusebenzisa imithombo zakamuva. Ekuqaleni kwalesi sigaba kwandisa ingcindezi uqala alulame kwenhliziyo, ukuphefumula ukunyakaza zenziwa asebenzayo. Phakathi naleso sikhathi, ukukhanya cishe hhayi umoya. Ngesikhathi esifanayo iqala zokunciphisa imisipha zokuphefumula obhekene okhishwa ngamakhala futhi ephefumula. Okwesikhashana kungenzeka alulame ukwazi. Ngenxa yokuntuleka oxygen kwezicubu ziqala ngokushesha buthelela imikhiqizo ungazange zabhekana namachibi. izinqubo umzimba ukuqhubeka kohlelo anaerobic.

Ngo nomunyu ngenxa amandla omlilo ezicutshini umuntu ATP ilahlekelwa umucu wakhe 50-80 g isisindo. Zibizwa ngokuthi "isisindo umphefumulo." Njengomthetho, agony ihlala isikhathi esifushane - akukho kuka imizuzu 5-6. Ezimweni ezingavamile ke ingahlala isigamu sehora. Ngemva kwalokho-ke, ukuncipha ingcindezi, ayeke senhliziyo esilimele uyama ukuphefumula.

Isigaba sokugcina

Isikhathi Smet emitholampilo - kusukela ngosuku ukuqedwa inhliziyo, CNS nokucindezeleka zokuphefumula kuze kube kuqale izinguquko ezingenakuhlehliswa ebuchosheni. exchange anaerobic ngenkathi ekuqhubekeni kusuka amasheya anqwabelene amaseli. Uma lezi imithombo run out, izicubu sezinzwa uyafa. Lapho ukungabikho ngokuphelele umoya-mpilo necrosis amaseli cortex futhi cerebellum luqala ngemva 2-2.5 imiz. Lezi amayunithi ebucayi kakhulu nokuntuleka O _{2 kukhona.} Ngemva kokufa cortex ngeke ibuyiselwe imisebenzi ebalulekile. Ngenxa yalokho, kuza ukufa yemvelo.

Izici

Lapho ngempumelelo yokusiza umuntu ukuba aphefumule ubude sebefile ngokuvamile wazinika isikhathi sesiphelile kusukela ukuboshwa inhliziyo ngaphambi ukubuya umzimba ekuphileni. izindlela zesimanje, njenge yesondlo wegazi kuze ubuncane ezidingekayo, igazi zokuhlanjululwa, umoya omncane, ukumpontshelwa nalowo onikele kwegazi, ukuvumela ukuba silondoloze ukuphila kule izicubu nerve isikhathi ngokwanele eside.

Ngaphansi kwezimo ezivamile sebefile ihlala imizuzu akukho kuka 5-6. On ubude bayo kuthonywa izici eziningi. Kahle kahle, lokhu kuyisizathu ifomu sokufa, izinga lokushisa komzimba, lizinga excitation yomzimba, ubudala, izimo kwaba ngaphansi kwazo kuncike nokunye. Kwezinye izimo, lokhu esigabeni kungathatha imizuzu engu-30. Ngokwesibonelo, ake sithi-ke kuyinto zalezi zinhlobo ukufa komuntu ngokuthi aminzisa emanzini abandayo, frostbite eqinile. Kulezi zimo, ngenxa enciphile inqubo exchange lokushisa, kuhlanganise eningi ebuchosheni, i kakhulu ingasheshi. Ukusebenzisa yokufakelwa hypothermia zokuvimbela isinyathelo isikhathi kungase kukhule kumahora angu-2.

Ngesikhathi esifanayo ngaphansi kwethonya kwezimo ezithile, ezinye izinhlobo sebefile zihlukile futhi mfushane. Ngokwesibonelo, lokhu kwenzeka uma abantu bayafa ngenxa omkhulu ukopha. Kulesi simo, izinguquko sokugembula kule izicubu sezinzwa, ngenxa okuyinto ukuphila ngeke ibuyiselwe, ukuthuthukisa ukumelwa inhliziyo.

I ngokucacile we ngezigaba

Naphezu kweqiniso lokuthi udaba ehushule ukuphila ezingaxazululeki kuze kube sekupheleni, kwezokwelapha isikhathi eside izinhlobo ukufa umahluko ngenombolo zindlela. Isigaba ukukhululwa yokuqala. Zikhona ezimbili - ukufa kobudlova engenalo udlame. Uhlanga ukhonza njengoba umbandela wesibili. Ngokusho kwalo, futhi lezi zinhlobo ezilandelayo ukufa engenalo udlame:

1. Ngokwendlela umzimba owakheke ngayo.
2. sokugembula
3. Kungazelelwe.

Kukhona kusigaba ubunjalo kanye ekunqanyulweni zokuphila ngenxa izici zangaphandle. Ngakho, ukukhulula lezi zinhlobo lokubulala kabuhlungu, njenge:

• Ukubulala.
• Ukuzibulala.
• Ukufa uma ingozi.

isigaba engeziwe

Okungenhla echazwe ezimbili izinhlobo ukufa.

ekuxilongweni

Enye kunzima kakhulu izigaba ngezigaba sinyathelo ekuboneni imbangela yokufa kwakhe. Kungenzeka eziyisisekelo, Lesisemkhatsini ngokushesha. Ososayensi banovalo yokwenza iphutha ekuhlonzweni, ukudala ekhethekile eziphilayo isampula noma kwakheka izimo ezikhethekile ecabangela ukungcwatshwa kwami. Ngokwesibonelo, e-Munich engaphezu kweyikhulu kwakukhona ithuna lapho isandla kamufi u nilimaza string kusukela ucingo. Yena kwakhala kanye kuphela. Kwabe sekuvela ukuthi, lokhu kwenzeka ngenxa isinqumo okukhulu mortis. Phakathi naleso sikhathi, mkhuba akukhona Kwesinye isigameko lapho morgue wakhululwa uyaphila, odokotela ngephutha kutholakala ukuthi uphethwe yini izinhlobo ukufa lula ezaziwayo.

Hlola umsebenzi zokuphefumula

Izinhlobo ukufa ukubuzisisa yi ebekwe. Njengoba omunye wabo eziphatha njengokuhlola i umsebenzi umgudu wokuphefumula. Kuze kube manje akukho bufakazi onokwethenjelwa nokuphepha yayo. Kuye izimo zangaphandle, odokotela basebenzisa uphaphe, nesibuko abandayo, ukuziphatha auscultation umoya. Winslow liyasetshenziswa isampula. Siqukethe eqinisweni lokuthi sitja amanzi ibekwe esifubeni komuntu. Ngokusho ukuguquguquka level yayo bahlulelwe ukunyakaza zokuphefumula. Ngesikhathi esifanayo i-isivunguvungu esikhulu somoya, umswakama high egumbini, ezokuthutha odlulayo, imfiva kungathinta Imiphumela yanoma yiziphi izifundo. Ngakho, iziphetho kuyoba ayilungile.

Ukulondolozwa umsebenzi inhliziyo kohlelo

Ukuhlonza Ukugula izinhlobo ukufa, odokotela eyenziwa auscultation inhliziyo, palpation ka-pulse izitsha neuropathy emaphakathi, kanye nesifiso inhliziyo. Nokho, lolu cwaningo ayikwazi njengomuntu onokwethenjelwa ngokuphelele. Ubufakazi futhi ezithakazelisayo ngokwanele ngisho nalapho kukhona kwegazi ubuncane Magnus isampula. Kuyinto Friend okhalweni umunwe. Lapho kukhona kwegazi zizomakwa blanching ikhava, azungeze tint cyanotic livela. Lapho constriction isuswe, umbala kwesikhumba, buyobuyiselwa.

Ukuphepha CNS umsebenzi

Lesi sibalo imele kubalulekile ukuze odokotela ekuxilongweni ezithile sokufa. Endaweni yesehlakalo ke ngokuyisisekelo kungenzeki ukuba ayothola ubuchopho ukufa. Ukulondolozwa umsebenzi CNS kufakazelwa ukungabi noma khona ukwazi, muscle, yokwenziwa isikhundla esifubeni ukusabela ezintweni ezenzeka ngaphandle (ammonia noma okuncane ubuhlungu ukuchayeka). sici ulwazi iyona reflex corneal. Kubonisa khona / ukungabikho ukusabela umfundi ukukhanya.
