Impedance - kuyini futhi yenziwa kanjani?

Phakathi nokuphila sisangulukile kungaba yasenzela phansi: ukwehla ukuzwa, ukubona, ukunuka. Ngezinye izikhathi kuyenzeka ekuseni kakhulu, ngezinye izikhathi - kunalokho sekwephuzile, kodwa ngandlela-thile sithola ukubona udokotela. Enye yalezi ochwepheshe - Otolaryngologist. Kuyinto yena uqonde izimbangela zokugula.

Impedancemetry: kuyini?

Impedance - kuyindlela wezinsimbi ukuxilongwa, esiza ukucacisa indawo kanye nohlobo ukulahlekelwa ukuzwa. Ngalo, ungathola ulwazi mayelana nesimo tube sokuzwa, cochlea, maphakathi nendlebe, kanye innervating yabo izinzwa.

Le ndlela ivumela ukuthola izifo ezifana perforation we eardrum, timpanoskleroz, patency kahle kuzo ngemibhobho sokuzwa, abezindaba otitis, otosclerosis nabanye.

impedancemetry Acoustic limelela othomathikhi nesilinganiso phuca conduction acoustic maphakathi nendlebe uma kushintshwa umfutho womoya ikholomu kanye nomthelela umsindo. Isifinyezo variable - i ukuvuma acoustic, noma conductivity izakhiwo indlebe yangaphandle futhi phakathi futhi impedance umsindo.

tympanometry

impedancemetry Acoustic kuhlanganisa umsindo conductivity nesilinganiso ngemva izinguquko umfutho womoya. Lokhu kubizwa ngokuthi yi tympanometry. I-apharathasi kuthola ushintsho ukuvuma lapho ingcindezi kwandisa ukuba amamilimitha angu ezingamakhulu amabili amanzi ikholomu uphinde wehlise ngezansi -400 amamilimitha angu.

Ukuvuma kuxhomeke endleleni umehluko phakathi kwengcindezi kule yangaphandle canal sokuzwa kanye maphakathi nendlebe okukhulu. Inani eliphakeme lokhu Inkomba ibhalisiwe esinjengalesi lapho ingcindezi efanayo. Timpatogramme okwamanje olukhonjiswa njengedifolthi intaba ephakeme kunazo zonke. Ukukhulisa noma ukwehlisa ingcindezi kunikeza isici ijika izinguquko. Ngokuvamile, kufanele ibukeke uhlamvu u- "L". umsebenzi kahle ka maphakathi nendlebe kushintsha amplitude kanye ukuma tympanogram.

Ukuphenywa umsebenzi ukupholisa tube sokuzwa

Impedance - kuyini? Lokhu indlela ukuxilongwa okujuli- isitho sokuzwa ngoba ukwehliswa yayo noma ukuhlanekezela. Esinye isizathu kungenzeka Eustachian tube ukungasebenzi. ibangelwa kuyendlulela adenoid izimila lokukhula, cleavage we kanzima ulwanga ipuleti, izifo oncological ikhala nomlomo, edema mucosal. Izingane ngezinye izikhathi waphawula sokuzwa tube patency ngenxa zokunciphisa izicubu kuyaqina kanye umsebenzi iziyaluyalu velum imisipha.

Impedance indlebe ukucacisa patency tube sokuzwa uhlukaniswe izigaba ezintathu:

1. isheke Safety. Okwenziwe ngesikhathi umfutho womoya nhlangothi zombili we ulwelwesi tympanic.
2. Experience Valsalva. I nasopharynx is eyayenziwe wadala-high blood pressure, kanti isiguli uyabuzwa ukuvala umlomo nekhala. Ngo evamile patency ipayipi okubaluleke kakhulu timpatogramme (isiqongo) kuvumelana esiphezulu ingcindezi iphuzu.
3. Yazi Toynbee. Ukubeka ukupholisa amathuba amashubhu Eustachian ngomfutho ongaphakeme. Ukuze wenze lokhu, isiguli buza fuza isiphuzo, ngemva ukuvala umlomo nekhala.

reflexometer

Ukuze uhlole ukuthi kukhona ukuncishiswa umsipha stapedius (yena ukudansela isiginci sakhe eardrum) ngemva kokungenwa imisindo usebenzisa impedancemetry acoustic. inqubo kanjani? Indlebe umsindo umthelela umfutho ezahlukene nevolumu ukuhlola reflex acoustic.

Ngo abantu enempilo, lokhu embundwini reflex esiphakathi kwama-decibel angu ayisithupha ukuba ayisishiyagalolunye. Ukushintsha isimo esishubile ulwelwesi tympanic ezilotshwe nhlangothi zombili, ngisho noma umsindo kwenziwa kuphela endlebeni eyodwa. Lokhu reflex libhekisela ngokuphelele.

Kunezindlela ezimbili ukwenza le nqubo yilezi:

1. Ipsilateral, lapho inyumbazana umsindo wakhonza indlebe, okumele uphenyo.
2. Contralateral, uma umsindo iqondiswa endlebeni, engesiyo njengamanje ngemibuzo.

Reflexometer ukusebenzisa umsindo imvamisa phakathi kwamakhulu amahlanu, inkulungwane, ayizinkulungwane ezimbili namakhulu amane amawaka hertz, futhi umsindo broadband.

Inani zokuxilonga inqubo

Kungani udinga impedancemetry? Kuyini futhi kufanele kungani kwenziwe? Le nqubo elula ivumela isiguli ukuhlonza conductive futhi sensorineural ubuthulu, ukunqotshwa lesikhombisa noma lwesishiyagalombili ezinzwa cranial, brainstem. Tadisha noninvasive, ngaphandle kobuhlungu futhi atholakale noma yikuphi nesineke, kungakhathaliseki ubudala noma inhlalakahle.

zindlela sokuxilonga ukuze sensorineural ubuthulu kukhona izimo elandelayo:

- reflex acoustic is baphawula ngaso umsindo ezingeni decibel angu esingaphansi amahlanu;
- ama-decibel angu kusuka amahlanu ayisishiyagalombili reflex eqoshiwe ngokulingana ukuthuthukisa umsindo;
- emva kwama-decibel angu ayisishiyagalombili reflex engekho.

reflexometer Acoustic akukuniki imiphumela conductive ubuthulu, ukuze ukwazi ukusebenzisa lesi sici ukuhlukanisa ke kusukela sensorineural. Ukunqotshwa kwe-nerve ebusweni ihlinzeka reflex ohlangothini contralateral, kodwa engekho - ukunqoba. Sekuvulwe icala lokuzama kokunikezwa kwe-sokuzwa emsipheni reflex umsebenzi kungekho kusukela indlebe ethintekile, noma kusukela enempilo.

ukuqapha impedance-pH

impedancemetry ngomphimbo: kuyini? Lokhu indlela yokunquma Kufinyeta kwemisipha odongeni emphinjeni, futhi edabula ke eziwuketshezi bese kuthi amagesi. Kusekelwe yokulinganisa ukumelana phakathi electrode amabili, okuyinto yethulwe ezingxenyeni ezahlukene tube wokugaya ukudla. Ngesikhathi esifanayo ucwaningo kukalwa asidi.

Inqubo ivumela ukucacisa uhlobo lwesifo Reflux (acid, hlangothi noma ane-alikhali), kanye oyiyo (igesi noma uketshezi). zindlela sokuxilonga ukuze Gerd (isifo gastroezofagialnoreflyuksnoy) kuphungula pH medium afika kwamane noma ngaphansi, kodwa ucwaningo lwamuva ukuphikisa lo mbono. Ngakho-ke, ukubaluleka wathola nsuku impedancemetry emphinjeni.

Ngenxa yalesi nesineke iqondiswa ngokusebenzisa stylet ekhaleni, okuyinto ahlelwe i-alinganayo isikhawu imitshina. Le divayisi ivumela ukubhalisa ngomphimbo peristalsis futhi asidi okuqukethwe olungena kulo kusukela esiswini.
