Izinga lokushisa lomzimba - i Isikhombisi esibalulekile empilweni yomuntu

lokushisa umzimba - inkomba ebaluleke kakhulu impilo umuntu, ngoba ngokuvamile kuba kuqubuka inkinga asathuthuka. Uma ukubaluleka ilungile ke sikhuluma normothermia. Khulisa - komzimba kanye hypothermia - a kwehliswe izinga lokushisa komzimba. lokushisa ovamile kule nesilinganiso ku ikhwapha ungaphakathi uhla kusuka 36 kuya 36,9⁰S. Nokho, akubona bonke ngakho elula.

lokushisa umzimba womuntu ezahlukene Icwele zangaphakathi nezangaphandle. Izibilini zihlanganisa okunemibandela nobuchopho. I "umongo" lokushisa njalo. Futhi lokho kuhlobene emtholampilo. It is kulinganiswa ngo lezi zindawo ezilandelayo: i-ingemuva, ngalo ingaphakathi ngomlomo, axilla. Kodwa kubalulekile ukwazi ukuthi ukubaluleka lokushisa nesilinganiso emlonyeni (lokushisa temlomo) ukuze 0.2-0.5 ngaphansi kwezingaqhwa rectal, ngaphandle axillary value (axilla) 0.5-0.8 degrees ngaphansana izinga lokushisa ingemuva . Ahlukanisa njengoba ungqimba ebusweni, noma "igobolondo", okuyiqembu ka 2,5 ukujula noma ngaphezulu. Amazinga lapha ziyahlukahluka kakhulu, hhayi nje kuphela ezindaweni ezihlukahlukene zomzimba, kodwa uthi ezahlukene imvelo. Ezindaweni ukhululekile we lokushisa lomzimba ezingqimbeni ebusweni 33-34⁰S womuntu nqunu, lapho izinga lokushisa isitaki ngalesi sikhathi kungase kube ngaphakathi 24-28⁰S. Ngokuvamile, le nkomba kuyinto oluyingozi kakhulu. izinga lokushisa emzimbeni unomphela ungase iyashintshashintsha usuku lonke kule ezahlukene kusuka 0.5 kuya 1,5⁰S kodwa namanje akuvamile idlule 1⁰S oscillations.

Yini izindlela ukuqinisekisa nokugcinwa lokushisa lomzimba wethu ezingeni njalo? Lokhu kufezwa buhlobo obunobunye ukushisa nokubanda izinqubo zokudlulisa ukushisa. ukukhiqizwa Heat kuyinto contractile futhi okungezona babeqhaqhazela ngenxa yezihlambi zemvula. Ngu izindlela contractile zihlanganisa yokuzithandela futhi okungalindelekile imisipha Kufinyeta: anda imisipha ithoni, ukuzamazama kwenzeke, umuntu owenza yimuphi umsebenzi. Amaphesenti non-ukuqhaqhazela thermogenesis ongafinyelela 70% emakhazeni. Umthombo brown izicubu adipose, nenqwaba okuyinto 1-2% we mass umzimba Imininingwane. Izindlela ukukhiqizwa ezifana ukushisa ibingakaziwa kodwa kusikisela ukuthi zihlobene yokuthi nezicubu eqhukethe khulula fatty acid, namachibi futhi okuyinto uphehla ukushisa.

Manje ake sixoxe inqubo ukudluliswa ukushisa, okuyinto kubalulekile ukuvimbela okweqile zomzimba. Inikeza kuze ukushisa emzimbeni kanje. Igazi okusekujuleni umzimba idlulisa ukushisa kwamanzi, lapho imithambo yegazi osuke usuvulekile ngenxa kushisa, lona imvelo. Ngaphezu kwalokho, ukubaluleka womjuluko womuntu futhi ukushisa okukhipha ngesimo amaza okushisa. Ngakho, sibonga ratio ukukhiqizwa ukushisa nokudlulisa ukushisa izinqubo we lokushisa lomzimba womuntu siyagcinwa uhla evamile.

Ukwanda lokushisa lomzimba ngenhla 37⁰S ngokuthi komzimba okukhulu. izimbangela ezivamile kwentuthuko ukwandisa kuma lokushisa kanye ukuphazamiseka okungu ukukhiqizwa ukushisa nokufudumala, okungukuthi, predominance ayengaphansi phezu yokugcina. Njengoba sekunama-izici ezibangela zihlanganisa izindlela ukuthi ukulindela ukwanda lokushisa, okuyinto, ngeshwa, akunakwenzeka njalo. Umuntu uyakwazi ukumelana ukubaluleka degrees 43 ngokwanele ngesikhathi esifushane. sokusinda amade kakhulu nganoma 42 degrees. Kodwa kubalulekile ukwazi ukuthi ngisho ngesikhathi 40-41 lamadigri ukulimala kobuchopho avele, isibonelo, ukuvuvukala yayo noma abathile befa izinzwa. Mayelana hypothermia uthi lapho izinga lokushisa emzimbeni ingezansi 35⁰S. Lokhu kungase kube ngenxa yokuthola umuntu isikhathi eside emakhazeni. Okokuqala, ukukhiqizwa ukushisa icubungula ukwanda, futhi ayikho ingozi emzimbeni, kodwa ke ziya ngokuya ngokuya mpilo, futhi kukhona Ukwehla kwezinga lokushisa. Uma ukwehla ifinyelela degrees 31, umuntu ulahlekelwa ukwazi. Ngezinye 24-28 degrees ngokuvamile ukufa kwenzeka.
