I-Polysomnography isifundo sokulala. Ngokuqapha eziningi zomzimba eduze, inhloso yokuhlola ukuthola ukuthi kukhona ukuphazamiseka kokulala.

I-Polysomnography wukuhlolwa okuphelele nokulinganisa okuvumela ukuthi kufundwe umzimba wokulala. Inhloso ukuhlola ukuthi kukhona yini ukuphazamiseka kokulala nokuzikala.

Ukuhlolwa akunabuhlungu futhi akunangozi. Kwenzeka isikhathi esiningi esibhedlela kepha, kwezinye izimo, kungenzeka ekhaya lalowo osithathayo.

I-Polysomnography ingabona ubukhona bezinhlobo eziningana zokuphazamiseka kokulala. Ake sicaphune:

• ukuvimbela ukuphefumula kokulala, okusho ukuphefumula okufushane kuyama ngesikhathi sokulala;
• imilenze syndrome engaphumuli, okungukuthi, ukunyakaza okungazibandakanyi kwezitho;
• ukuhlukunyezwa, okusho ukozela okukhulu nokuhlaselwa ubuthongo emini);
• snoring ngokweqile;
• noma ngisho nokuqwasha.

I-Polysomnography ivame ukwenziwa ebusuku. Ngakho-ke isiguli sifika esibhedlela ngayizolo futhi sibekwa egumbini elihlinzekelwe le njongo.

Ama-electrode abekwe ekhanda, ebusweni, esifubeni, kodwa nasemilenzeni nasezingalweni, ukukala:

• umsebenzi wobuchopho - i-electroencephalography ;
• ukusebenza kwemisipha esilevini, izingalo nemilenze - isibalku ;
• umsebenzi wenhliziyo - electrocardiography ;
• umsebenzi wamehlo, okusho ukunyakaza kwamehlo - i-electrooculography.

Futhi, i-polysomnography ingalinganisa:

• ukungena komoya, okusho ukuhamba komoya ongena ngamakhala nangomlomo, ngenxa yencamu yamakhala ekhethwe ngaphansi kwekhala;
• umsebenzi wemisipha yokuphefumula (okusho imisipha ye-thoracic neyesisu), sibonga ibhande elibekwe ezingeni lesifuba nesisu;
• ukuhona, okusho ukudlula komoya ngezicubu ezithambile zolwanga noma uvula, ngenxa yombhobho obekwe entanyeni;
• ukusuthiswa komoya-mpilo ku-hemoglobin, isb.izinga le-oxygen elikhona egazini, sibonga inzwa ethize ebekwe ekugcineni komunwe;
• ukulala emini;
• noma ukunyakaza okungazibandakanyi okuhlobene nokulala, isikhundla salowo olele noma umfutho wegazi.

Qaphela ukuthi kunconywa ukuthi ungaliphuzi ikhofi futhi ugweme utshwala obuningi ngosuku olwandulela ukuhlolwa. Futhi, kubalulekile ukwazisa udokotela nganoma yiziphi izindlela zokwelashwa ezilandelwayo.

Imvamisa, i-polysomnogram eyodwa yanele ukuhlola ukulala nokuthola kahle inkinga uma ikhona.

Abaqaphi bezivivinyo:

• amagagasi abonisa imijikelezo ehlukene yokulala;
• ukunyakaza kwemisipha;
• imvamisa yokuphefumula, okungukuthi lapho ukuphefumula kuphazamiseka okungenani imizuzwana eyi-10;
• imvamisa ye-hypopnea, okungukuthi, lapho ukuphefumula kuvinjwe kancane imizuzwana eyi-10 noma ngaphezulu.

Abasebenzi bezokwelapha banquma inkomba ye-apnea hypopnea, okungukuthi inani le-apnea noma i-hypopnea elinganiswa ngesikhathi sokulala. Inkomba enjalo elingana noma engaphansi kuka-5 ithathwa njengejwayelekile.

Uma amaphuzu angaphezu kuka-5, kuyisibonakaliso sokuphefumula kokulala:

• phakathi kuka-5 no-15, sikhuluma ngokuphefumula okuncane kobuthongo;
• phakathi kuka-15 no-30, kuba ukuphefumula kokulala okulingene;
• futhi lapho sesineminyaka engaphezu kwengu-30, siba nesifuba sokulala.
