Uyini umfutho womoya kubhekwa evamile?

Umhlaba Wethu ine emkhathini, kuyinto ifaka ingcindezi konke okuphakathi kwalo. Ngo 1634, i-Italy usosayensi Torricelli Inani lokuqala kunqunywa uyalingana umfutho womoya. Umthelela ekuhloleni kwabantu izinguquko zalo, ososayensi amakhono ehlukene. Kwabe sekuvela ukuthi, lo umfutho womoya incike lokushisa, umoya ukuminyana, engamamitha, amabutho ezikhangayo, latitude. Kuyinto kuncike ekushintshashintsheni njalo.

Iyini ingcindezi emoyeni kuvamile? Yini lokho? Physicists uthi: 760 amamilimitha angu mercury. Imiphumela kufanele ibe ngaso kogu lolwandle, futhi izinga lokushisa kufanele luhambisane degrees 15.

Ngezinye evamile ingcindezi emzimbeni square isentimitha nezenzo njengoba isisindo elilingana 1.033 kg, kodwa asazi ukuphawule. Lokho kungenxa yokuthi umoya amagesi ziyoncibilika izicubu eziwuketshezi. Basuke silinganise ngokugcwele ingcindezi umkhathi. Disequilibrium nge sezulu ushintsho ibonwa njengoba Ukuwohloka impilo. Uyini umfutho womoya kubhekwa evamile? Ngokusobala, umuntu ongenawo nemiphumela emibi emzimbeni. Ngokusho odokotela, kuba elilingana 750 mm. HG. Art.

Nokho, abantu abahlala ezindaweni ngenhla noma ogwini lolwandle endaweni ingcindezi njalo eliphezulu kakhulu noma eliphansi, ukujwayeza kahle ke adlulisiwe. Ngakho-ke, lokho umfutho womoya kubhekwa impilo evamile futhi kuncike lithathelwe yethu.

Iyimbi asithinti nje kuphela umfutho womoya uqobo, njengoba izinguquko zalo okusheshayo. Ingcindezi linyuka noma lehla imbangela Ukuwohloka ezempilo, kanye nezinkinga zenhliziyo. Jwayelekile umfutho womoya for human imperceptible. Nokho, lolu shintsho okusheshayo emoyeni walo sibhajwe izimbotshana ezihlukahlukene zomzimba, ke enza izinto yangaphakathi izitho baroreceptors. Kwezinye abantu babe ukungakhululeki, ubuhlungu emalungeni, kukhona ingcindezi yokwanda kwama kanye nezinye izenzakalo ezingajabulisi.

Ngokwesibonelo, eardrums obuhlungu, bakhathazekile ubuhlungu esiswini. Lokhu kungenxa yokuthi umoya e izimbotshana yomzimba, ingcindezi phezu kwezingange zawo. Lokhu kuyiqiniso ikakhulukazi phakathi zasezindaweni. Anticyclones nomthelela omkhulu ngaphansi omubi emzimbeni.

Kungase kube buhlungu enhliziyweni, ngenxa yesifo senhliziyo, inhliziyo isigqi iziyaluyalu. Isiyezi, izinhlungu inhliziyo, iphika - lena izikhalazo ejwayelekile kakhulu. Isimiso sezinzwa iyaphendula lenyuka ukukhathazeka, ukucasuka. Kwezinye abantu, kukhuphuke ubudlova nezingxabano. Blame amaza ivela baroreceptors ebuchosheni ngesikhathi asemkhathini ingcindezi izinguquko.

Ukuthembela zempilo sezulu - yilokho meteozavisimost. It is kakhulu liphinyiselwe ngezindlela abantu abanezifo ezingamahlalakhona imithambo, inhliziyo, amaphaphu kanye namalunga.

Uyini umfutho womoya kubhekwa evamile endaweni yakho, sicela uvakashele isiteshi sezulu. Ngokuvamile ababikezeli bezulu ku projection yokucindezela kumphumela iphuzu ngalinye ingcindezi at kolwandle ku ifomula ekhethekile.

Ukushintsha umfutho womoya kubaluleke ngokukhethekile lapho nokuphakamisa ukuphakama enkulu. izintaba High encishisiwe-mpilo ingcindezi esinqunyiwe. Lokhu kuholela ukwehla saturation igazi kubo kanye nokuthuthukiswa hypoxia - kokuwa noma entabeni, lesi sifo. Ngezinye ephakeme edema yamaphaphu kungenzeka, okuholela ukungabi khona ukwelashwa ukufa.

Lapho izindiza gumbi depressurization at kokuwa eliphezulu iconsi elibukhali ingcindezi kuholela yokuthi zonke emzimbeni womuntu uketshezi ngamathumba. Ukuthuthukisa semithambo emoyeni embolism, ukukhubazeka, paresis, nokumelwa yinhliziyo izitho ezihlukahlukene.

I umfutho womoya kumele kubhekwe hhayi kuphela kubangele ukuphakama omkhulu, kodwa futhi umsebenzi ehlangene shintsho imvelo nge ongaphakeme noma ukunyuka komfutho wegazi. Ukuze wenze lokhu, sebenzisa amakhamera akhethekile bachachamba. Ukwephula nokuphepha ngenkathi usebenza kuzo kungaholela decompression ukugula.

Uma sihlupheka meteodependent, ukubukela sezulu. Isikhathi esithathwayo yimithi kuzokuvumela kalula uthumele asemkhathini umfutho okhuphuka ngokungazelelwe.
