Polysomnography chidzidzo chekurara. Nekutarisa akawanda physiological pedyo, chinangwa chekuongorora ndechekuona kuvapo kwekuvhiringidzika kwekurara.

Polysomnography ndeye yakazara uye bhenji bvunzo inobvumira iyo physiology yekurara kuti idzidzwe. Chinangwa ndechekuongorora kuvepo kwekusagadzikana kwekurara uye kuverengera.

Bvunzo harirwadzi uye harina njodzi. Zvinoitika nguva zhinji muchipatara asi zvinogona, mune dzimwe nguva, kuitika kumba kwemunhu anenge azvitora.

Polysomnography inogona kuona kuvepo kwemhando dzinoverengeka dzezvinetso zvekurara. Ngatitorei mashoko:

• kuvharidzira kufema kwehope, kureva kufema kupfupi kunomira panguva yekurara;
• kusagadzikana kwemakumbo syndrome, kureva, kufamba kusingazviiti kwemakumbo;
• narcolepsy, kureva kurara zvakanyanya uye kurara masikati;
• ngonono zvakanyanyisa;
• kana kunyange kushaya hope.

Polysomnography inowanzoitwa usiku. Naizvozvo murwere anosvika kuchipatara zuva rakapfuura oiswa mukamuri rakapiwa nokuda kwechinangwa ichi.

Electrodes anoiswa pamusoro pemusoro, kumeso, chipfuva, asiwo pamakumbo nemaoko, kuyera:

• basa rehuropi - electroencephalography ;
• kuita tsandanyama muchirebvu, mawoko nemakumbo - electromyography ;
• kushanda kwemoyo - electrocardiography ;
• kushanda kwemaziso, kureva kufamba kwemaziso - electrooculography.

Zvakare, polysomnography inogona kuyera:

• kufefetedza, kureva kuyerera kwemhepo ichipinda nemumhino nemuromo, nekuda kwe cannula yemhino yakaiswa pasi pemhino;
• basa remasumbu ekufema (kureva mhasuru yechipfuva nedumbu), nekuda kwetambo yakaiswa pamwero wechipfuva uye dumbu;
• kuridza ngonono, kureva kufamba kwemhepo kuburikidza nematishu akapfava emukanwa kana kuvhuvhuta, nekuda kwemaikorofoni yakaiswa pamutsipa;
• kuzara kweokisijeni muhemoglobin, kureva mwero weokisijeni iripo muropa, nekuda kweimwe sensor yakaiswa pamuromo wemunwe;
• kurara kwemasikati;
• kana kunyange kufamba kusingaite kune chekuita nekurara, nzvimbo yemunhu akarara kana BP.

Cherechedza kuti zvinokurudzirwa kusadya kofi uye kudzivisa doro rakawandisa zuva risati raongororwa. Zvakare, zvakakosha kuzivisa chiremba nezve chero marapirwo emushonga anoteverwa.

Kazhinji, imwe polysomnogram inokwana kuongorora kurara uye kunyatsoona dambudziko kana riripo.

Vatariri vebvunzo:

• masaisai emhando yenguva dzakasiyana dzekurara;
• kufamba kwemhasuru;
• kuwanda kwe apnea, kureva kuti kana kufema kunovhiringwa kwemasekonzi gumi;
• kuwanda kwe hypopnea, ndiko kuti, kana kufema kwakavharwa zvishoma kwemasekonzi gumi kana kupfuura.

Vashandi vezvokurapa vanosarudza index of apnea hypopnea, kureva nhamba yeapnea kana hypopnea inoyerwa pakurara. Indekisi yakadaro yakaenzana kana kuti isingasviki 5 inoonekwa seyakajairika.

Kana zvibodzwa zvakakura kudarika 5, chiratidzo chekushaya hope:

• pakati pe5 ne15, tinotaura nezvekupnea kwehope;
• pakati pemakore 15 ne30, kutadza kufema munhu akarara kuri pakati nepakati;
• uye kana yava nemakore anopfuura 30, kutadza kufema kwakakomba.
