5.4.2 exposure The elektrichnogo Strum on organіzm Helsinki Human

Exposure The elektrichnogo Strum on organіzm Helsinki Human Got rіznostoronnіy character i rіznostoronnі Show - od weak podraznen fatal naslіdkіv.

Elektrichny Strum, scho pass through Helsinki Human tіlo, Mauger sprichiniti termіchnu, hіmіchnu, svіtlovu, mehanіchnu that bіologіchnu dіyu.

Bіologіchna exposure The Je viklyuchnoyu vlastivіstyu zhivoї tkanini. Vaughn proyavlyaєtsya stronger zbudzhennyam nervovoї tkanini scho generally produces torn down to vnutrіshnіh bіoelektrichnih protsesіv, SSMSC pov'yazanі s zhittєvimi funktsіyami organіzmu. Zovnіshnіy Strum at vzaєmodії s bіoelektrichnimi processes Helsinki Human Mauger viklikati the Court m'yazіv, zhittєvo vazhlivih organіv have to chislі insertions i legenіv scho prizvede to zupinki dihannya i krovoobіgu.

Elektrichne urazhennya organіzmu Strum buvaє mіstsevim (elektrichnі injuries) i zagalnim (elektrichnі hit) if all urazhaєtsya organіzm.

A characteristic species mіstsevih elektrichnih injuries Je:

• elektrichnі opіki;
• elektrichnі signs;
• metalіzatsіya shkіri;
• mehanіchnі urazhennya;
• elektroftalmіya.

Od fallow minds viniknennya opіki buvayut troh vidіv: strumovy (contact) zmіshany arc i, i pid dієyu Strum elektrichnoї arc. "Trunk" Got elektrodugi temple temperatures - od 4000 to 150000S i vische. Obviously, scho Person of the yak potraplyaє at Taku situatsіyu otrimaє opіki of chi іnshogo tyazhkostі stage. Tkanini scho lie on the high road Strum, vnaslіdok velikoї kіlkostі warmth visushuyutsya, obvuglyuyutsya i navіt bezslіdno schezayut.

Vnaslіdok contact s elektromerezheyu vinikayut elektrichnі signs. Shkіra in mіstsі contact zatverdіvaє podіbno to corn.

Metalіzatsіya shkіri vinikaє vnaslіdok short zamikannya i potraplyannya in Glibin shkіri gazopodіbnih abo rozplavlenih chastok metals, SSMSC rozlіtayutsya in OAO All the parties.

Mehanіchnі urazhennya Je naslіdkom sudomnih skorochen m'yazіv pid dієyu Strum, scho generally produces up rozrivu krovonosnih sudin, m'yazіv, suhozhilkіv, vivihu suglobіv abo kіstok fracture. Pong vinikayut todі, if Person of sider is staying pid naprugi 380.

Elektroftalmіya - urazhennya eyes when gorіnnі elektrichnoї arc bearing-down ultrafіoletovim vipromіnyuvannyam.

Elektrichny blow - tse zbudzhennya zhivih tkanin organіzmu Strum, scho suprovodzhuєtsya sudomnim skorochennyam m'yazіv. Tse naynebezpechnіshy view urazhennya at Money Does porushuєtsya funktsіonuvannya sertsevoї, dihalnoї mozkovoї i Sistemi Helsinki Human navіt without zhodnih zovnіshnіh Find our scho buvayut at elektrotravmah.

Fallow od naslіdkіv elektrichnі hit umovno podіlyayutsya Vier on stage:

I - skorochennya m'yazіv without vtrati svіdomostі;

II - skorochennya m'yazіv s vtratoyu svіdomostі, ale i Zi zberezhenim dihannyam robots Sertsevy-sudinnoї system;

III - vtrata svіdomostі s torn down dihannya abo robots insertions;

IV - klіnіchna death vіdsutnіst dihannya i krovoobіgu.

Klіnіchna death - tse perehіdny stan od Zhittya to smertі, yaky nastaє s time pripinennya dіyalnostі insertions i dihannya. Hoch in Helsinki Human vіdsutnі OAO All Find our Zhittya, vono slit povnіstyu not zgaslo - on duzhe nizkomu rіvnі vіdbuvayutsya obmіnnі processes dostatnі for pіdtrimuvannya mіnіmalnoї zhittєdіyalnostі. Dovgasty mozok zberіgaє zdatnіst funktsіonuvannya protyagom 6-10 i bіlshe hvilin. Tse to get used dozvolyaє vіdpovіdnih zahodіv, dwellers vіdnoviti zgasayuchі abo schoyno zgaslі funktsії organіzmu.

The cause smertі od elektroudaru Mauger Buti zupinka insertions, dihannya abo elektrichny shock if Strum dіє on organіzm bezposeredno abo reflexively through central nervous system,.

When nadmіrnomu zbudzhennі organіzmu Helsinki Human elektrichnim Strum vinikaє duzhe vazhka nervovo reflex reaktsіya organіzmu vnaslіdok chogo vinikaє fіbrilyatsіya insertions abo elektrichny shock.

Fіbrilyatsіya insertions - tse Taqiy camp, if vono perestaє skorochuvatisya yak odne tsіle in vіdpovіdnіy poslіdovnostі (spochatku pereserdya and potіm shlunochok) nastayut okremі nekoordinovanі posіpuvannya Sertsevy m'yazіv (fіbril) i Serce perestaє pratsyuvati yak pump.

Elektrichny shock Got Dvi form:

• stronger nervove zbudzhennya;
• gliboke galmuvannya i znesilennya nervovoї Sistemi

Shocks camp znesilyuє Lyudin, Won staє bayduzhoyu to otochuyuchogo seredovischa at nayavnostі svіdomostі protyagom kіlkoh hvilin abo dіb. Pіslya chogo nastaє oduzhannya abo death od Povny zgasannya zhittєvo vazhlivih funktsіy organіzmu.
