Kuyini ingcindezi evamile asemkhathini

Atmosphere - igobolondo ashukumisayo, okuyinto kushintsha njalo - kokubili zonyaka kanye diurnal. Le ndoda, isakhamuzi eside isikhathi yakithi efanayo, njengoba umthetho, engazizwa lezi zinguquko, ngoba umzimba akwazi ukujwayela ngesikhathi esifanele ngabo. Ngakho-ke, ushintsho sezulu, ngaphandle kakhulu, cishe akukho nomthelela isimo impilo yabantu enempilo.

Kodwa kukhona esigabeni sabantu sezulu ebucayi, lapho umfutho womoya kunomthelela eziphathekayo kakhulu. Labo abaphethwe yizifo ezingamahlalakhona, kuba ikakhulukazi kulabo abahlobene isimiso sezinzwa futhi senhliziyo, njengoba njalo elukhuni ukuthwalwa izinguquko sezulu. Bobabili izigaba ungazizwa yokucindezela isici esifundeni, futhi lokhu akusho ukuthi evamile umfutho womoya. Lesi sakamuva, ngenhlanhla kaningi ngakho yendalo. Kukholakala ukuthi kunamandla umfutho womoya ku ikholomu unit endaweni at latitude 45 degrees futhi engamamitha 0 amamitha (kolwandle). Phakathi ingcindezi evamile asemkhathini ukuthatha 760 mmHg.

Nge ukuphakama lesi silinganiso kuyehla, futhi kukhona barometric ifomula ekhethekile ukubala ukucindezela nganoma yisiphi isikhathi, ngokwazi ukuphakama kwakhe. Ngokwesibonelo, i-Moscow ukuphakama isilinganiso 156 m inani lingu 746 mm. Lokhu kuyinto evamile yendawo, kodwa hhayi ukucindezela evamile asemkhathini - lezi imiqondo kumele ahlukaniswe.

Nakuba ezimweni wegazi ophezulu, abakwazi ukubona noma yiluphi ushintsho ngoba akuhlukile kangako kusukela evamile. Kuphela ngesikhathi izinguquko eliphezulu ngokwedlulele ezidlula ziqala ukuvela: ukuphefumula kuba ezingavamile kodwa ajulile eqhubeka ekhaleni imizwa, indlebe lehla, futhi izwi ithulisiwe, futhi kome lwamafinyila uveta ndikindiki okuncane kwesikhumba. Kodwa zonke lezi zici okulula ukuyiphatha.

Ingabe nezikhathi ezingezinhle ngaphezulu ngokuzumayo ingcindezi izinguquko - kokucindezelwa (ukwanda) futhi decompression ethile (ukunciphisa kokujwayelekile). Lapho ukucindezela kwandisa umthamo amagesi ziyoncibilika igazi, futhi usuke okusheshayo emuva value encishisiwe igesi ngokweqile (mhlawumbe nitrogen) zanqwabelana egazini. Negesi Bubbles clog imithambo yegazi, ekubeni imbangela yezifo eziningi. Ngakho-ke, kancane lezi zinguquko, ngcono ke uvuma umzimba womuntu.

Ithonya umfutho womoya wokuthi bonke owanqoba lubonakale kokuphakama izinguquko. Ezintabeni emva uphawu 2500 amamitha umuntu neakklimatizirovanny uzizwa ebuthakathaka ngenxa umoya-mpilo indlala. Ophilisayo futhi ukuphefumula elijulile, njalo ukusikwa inhliziyo incipha blood pressure. Konke lokhu kungenxa umphumela ukuphakama, futhi ngenxa yalokho, ingcindezi ongaphakeme, okubangela yisimo esibuhlungu njengoba hypoxia, noma engamamitha ukugula. Lesi simo esiyingqayizivele sibangelwa lunganqotshwa, kokuba ngazivumelanisa nendlela futhi ejwayele izimo entsha umzimba. Kuyaphawuleka ukuthi abantu entabeni ungazizwa ukugula, ukuphila konke ukuphila kwakhe engamamitha 2000 amamitha noma ngaphezulu - ngoba yabo blood pressure ongaphakeme kuyinto evamile.

Kodwa-ke akudingekile ukuya ezintabeni noma ukuwela izimo ezimbi kakhulu. Ingcindezi amathonsi kungaba buhlungu kakhulu edolobheni lakubo, ikakhulukazi abantu nempilo ebuthaka. Ukuze lokhu kumelwe uzilungiselele. Lapho isimo sezulu kulindeleke ukuwohloka eningi efiselekayo ukunciphisa umzimba ukucindezeleka, uvalo ungazami ukuqinisekisa nokuzola. Uma lithathelwe ngokuvamile kwenzeka kunzima, kungcono ukuthatha izindlela ezinconywe kudokotela.

Futhi, ungakhohlwa ukuthi ingcindezi evamile asemkhathini akuyona into evamile sezulu kunoma iyiphi isimo sezwe. Esifundeni ngasinye, kuye ngokuthi ukuphakama, ingcindezi isici zizohluka.
