• Kwenziwa kanjani ukuhlolwa

Ukuhlolwa kwe-BERA, okwaziwa nangokuthi i-BAEP noma i-Brainstem Auditory Evoked Potential, ukuhlolwa okuhlola lonke uhlelo lokuhlola, ukubheka ukuba khona kokulahleka kokuzwa, okungenzeka ngenxa yokulimala kwe-cochlea, i-auditory nerve noma i-brainstem.

Yize kungenziwa kubantu abadala, ukuhlolwa kwe-BERA kwenziwa kaningi ezinganeni nasezinsaneni, ikakhulukazi uma kunengozi yokulahlekelwa ukuzwa ngenxa yezimo zofuzo noma uma kunomphumela oshintshiwe ekuhlolweni kwendlebe, okuwukuhlolwa okwenziwe ngokushesha nje ngemva kokuzalwa futhi lokho kuhlola amandla engqondo okushiwo usana olusanda kuzalwa. Qonda ukuthi ukuhlolwa kwendlebe kwenziwa kanjani nemiphumela.

Ngaphezu kwalokho, lolu vivinyo lungabuye lu-odolwe ezinganeni eziye zabambezela ukuthuthukiswa kolimi, ngoba lokhu kubambezeleka kungaba uphawu lwezinkinga zokuzwa. Funda ukuthi ungabona kanjani uma ingane yakho ingalaleli kahle.

Yini isivivinyo se-

Ukuhlolwa kwe-BERA kukhonjiswa ikakhulukazi ukuhlola ukukhula nokuphendula kwezingane, izinsana ezisanda kuzalwa, izingane ezine-autistic noma labo abanezinguquko zofuzo, njenge-Down's Syndrome.

Ngaphezu kwalokho, ukuhlolwa kungenziwa futhi ukuxilonga ukulahleka kokuzwa kubantu abadala, uphenye imbangela ye-tinnitus, ukuthola ubukhona bezimila ezibandakanya imizwa yezindlebe noma ukuqapha iziguli ezibhedlela noma ezibambekayo.

Kwenziwa kanjani ukuhlolwa

Isivivinyo sihlala phakathi kwemizuzu engama-30 nengama-40 futhi sivame ukwenziwa ngenkathi ulele, njengoba kuyisivivinyo esibucayi kakhulu, ngakho-ke, noma yikuphi ukunyakaza kungaphazamisa imiphumela yokuhlolwa. Uma ingane ihamba kakhulu ngesikhathi sokulala, udokotela angaluleka ukuthi ihlalise ingane isikhathi sokuhlolwa, ukuqinisekisa ukuthi akukho ukunyakaza nokuthi umphumela awushintshiwe.

Ukuhlolwa kuqukethe ukubeka ama-electrode ngemuva kwendlebe nasebunzini, ngaphezu kwehedsethi ebhekele ukukhiqiza imisindo ezokwenza kusebenze ubuchopho kanye nezinzwa zokuzwa, kukhiqize ama-spikes kugesi ngokokuqina kwesikhuthazi, esithathiwe nge-electrode futhi kwahunyushwa ngudokotela kusuka kumagagasi omsindo aqoshwe imishini.

Ukuhlolwa kwe-BERA akudingi ukulungiswa okukhethekile futhi kuyinkqubo engeyona eyokuhlasela engabangeli ubuhlungu noma ukungaphatheki kahle.
