Impedance - abin da yake da shi da kuma yadda yana da za'ayi?

A lokacin da rayuwar mu hankula iya bari mu saukar: karu a ji da gani, ƙanshi. Wani lokacin shi ya faru sosai da wuri, wani lokacin - m marigayi, amma ko ta yaya muka samu don ganin likita. Daya daga cikin wadannan masana - otolaryngologist. Shi ne wanda ya zai gane Sanadin ailments.

Impedancemetry: abin da yake da shi?

Impedance - shi ne wani instrumental Hanyar ganewar asali, wanda taimaka ƙayyade da wuri da kuma yanayi na ji hasara. Tare da shi, za ka iya samun bayanai game da halin da auditory tube, cochlea, tsakiyar kunne, kazalika da su innervating jijiyoyi.

Wannan hanya damar gane cututtuka irin perforation na eardrum, timpanoskleroz, illa patency na auditory shambura, otitis kafofin watsa labarai, otosclerosis da sauransu.

Kiya impedancemetry wakiltar atomatik ji karfi Ft Irfan madugu a tsakiyar kunne a lokacin da canza iska shafi matsa lamba da kuma tasiri sauti. Takaitacciyar m - wani Ft Irfan ƙofar shiga, ko watsin da Tsarin cikin matsanancin da kuma tsakiyar kunne da kuma sauti impedance.

tympanometry

Kiya impedancemetry hada da sauti watsin ji bayan iska matsa lamba canje-canje. Wannan ake kira tympanometry. The inji detects da canji a ƙofar shiga lokacin da matsa lamba a ƙara a ɗari biyu millimeters na ruwa shafi da kuma rage shi a kasa -400 millimeters.

Ƙofar shiga dogara a kan yadda mai girma bambanci tsakanin matsa lamba a cikin waje auditory canal da kuma tsakiyar kunne. A mafi darajar wannan index aka rajista a lokacin da wannan matsa lamba. Timpatogramme a wannan lokaci da aka nuna a matsayin girma ganiya. Kiwon ko rage matsin bada halayyar kwana canje-canje. Yadda aka saba, shi ya kamata ka duba kamar harafin "L". Sosai aiki na tsakiyar kunne ya musanya mawadãta, kuma siffar da tympanogram.

Bincike na samun iska aiki na auditory tube

Impedance - abin da yake da shi? Wannan hanya na da cikakken jarrabawa na auditory sashin jiki domin ta rage ko murdiya. Daya dalilin iya zama Eustachian tube tabarbarewa. Its hanyar zoba adenoid ciyayi girma, da tsakiyan nonon da wuya palate farantin, oncological cututtuka na hanci da baki, mucosal edema. Yara a wani lokaci ana lura auditory tube patency saboda da akan rage nama elasticity da kuma aiki cuta velum tsokoki.

Impedance na kunne domin sanin patency na auditory tube ne zuwa kashi uku, saukarwa:

1. Safety rajistan shiga. Yi a yanayi matsa lamba a garesu na tympanic membrane.
2. Experience na Valsalva. A nasopharynx ne tsari na wucin gadi hawan jini, da kuma da mãsu haƙuri aka tambaye don rufe bakin da hanci. A al'ada patency bututu mafi darajar a kan timpatogramme (ganiya) yayi daidai da matsakaicin matsa lamba batu.
3. Fuskanci Toynbee. Kayyade iska yiwuwa Eustachian shambura a low matsa lamba. Don yin wannan, da haƙuri da aka tambaye su dauki abin sha, bayan rufe bakin da hanci.

reflexometer

Domin duba ko akwai wata rage daga cikin stapedius tsoka (ta na jan da eardrum) bayan daukan hotuna zuwa sauti ta amfani da Ft Irfan impedancemetry. Ta yaya ne hanya? Kunnen amo tasiri na daban-daban tsanani da kuma juz'i na duba Ft Irfan reflex.

A m mutane, wannan reflex bakin kofa ne tsakanin sittin zuwa casa'in decibels. Canza tashin hankali na tympanic membrane an rubuta a garesu, ko da idan sauti ne yake aikata kawai a daya kunne. Wannan reflex nufin da cikakkar.

Akwai hanyoyi biyu don yin wannan hanya:

1. Ipsilateral, a lokacin da sauti kadaici yana bauta a kunne, wanda dole ne a bincika.
2. Contralateral, idan amo ne directed a cikin kunne, wanda ba a halin yanzu a karkashin binciken.

Reflexometer yin amfani da sauti da mita ɗari biyar, da dubu, dubu biyu da hudu dubu hertz, kuma broadband amo.

The bincike darajar da hanya

Don me kuke bukatar impedancemetry? Mẽne ne, kuma me ya sa ya kamata shi a za'ayi? Wannan gwada da sauki hanya damar haƙuri a gano conductive da kuma sensorineural ji hasara, da shan kashi na bakwai ko takwas girman kwanyar jijiya, brainstem. Nazarin noninvasive, m da kuma samuwa ga wani haƙuri, la'akari da shekaru da jindadin.

Bincike da sharudda ga sensorineural ji hasara ne da wadannan yanayi:

- Ft Irfan reflex aka lura a cikin amo matakin na kasa da hamsin decibels.
- daga hamsin zuwa tamanin decibels reflex rubuce a cikin rabo don bunkasa sauti.
- bayan da tamanin decibels reflex ne mãsu fakowa ba.

Kiya reflexometer ba ya bayar da sakamakon da conductive ji hasara, don haka ba za ka iya amfani da wannan alama a bambance shi daga sensorineural. Da shan kashi na gyara man fuska jijiya samar da wani reflex a kan contralateral gefe, amma da yake babu - kayar. A hali na take hakkin da auditory jijiya reflex aiki ba daga shafa kunne, ko daga lafiya.

impedance-PH monitoring

Esophageal impedancemetry: abin da yake da shi? Wannan hanya domin kayyade murdede contractions daga cikin esophagus bango, da kuma wucewa ta hanyar da shi ruwan da kuma gas. Yana dogara ne a kan aunawa da juriya tsakanin biyu wayoyin, wanda aka gabatar a sassa daban daban na narkewa kamar bututu. A lokaci guda bincike da aka auna acidity.

A hanya damar domin sanin irin reflux cuta (acid, tsaka tsaki ko alkaline), da kuma tsarinta (gas ko ruwa). Bincike da sharudda ga Gerd (gastroezofagialnoreflyuksnoy cuta) ne don rage PH daga cikin matsakaici har zuwa hudu, ko kasa, amma kwanan nan nazarin ɓãta wannan ka'idar. Saboda haka, da muhimmancin samu kullum impedancemetry esophagus.

Domin wannan haƙuri ne gudanar ta hanci stylet, wanda aka shirya a wani daidai tazara gane. Wannan na'urar damar yin rajistar esophageal hanji suna da acidity abun ciki wanda da dama a cikin da shi daga ciki.
