Impedance - chii uye sei rinoitwa?

Mumakore upenyu hwedu pfungwa kunogona ngatirambei pasi: kuderera vachinzwa, achiona, hwema. Dzimwe zvinoitika mangwanani kwazvo, dzimwe nguva - asi vanonoka, asi sezvineiwo tinowana kuona chiremba. Rimwe nyanzvi idzi - otolaryngologist. Ndiye vachanzwisisa zvinokonzera zvirwere.

Impedancemetry: chii?

Impedance - ane nzira paku pamusoro nechirwere, iyo inobatsira kuona nzvimbo uye hunhu kunzwa kurasikirwa. With izvozvo, unogona kuwana mashoko pamusoro chinzvimbo pakati auditory chubhu, cochlea, pakati nzeve, uyewo avo innervating tsinga.

Nzira iyi inobvumira kuti rione zvirwere zvakadai perforation ari eardrum, timpanoskleroz, havachanyatsogoni patency pamusoro auditory sepombi, otitis venhau, otosclerosis uye nevamwe.

Acoustic impedancemetry inomiririra otomatiki nekuyera fura acoustic conduction pakati nzeve kana kuchinja mhepo mbiru kufurirwa nezvainoita ruzha. Pfupiso shanduka - ane acoustic kupinda, kana conductivity pamusoro Zvivako wokunze uye pakati nzeve uye kurira impedance.

tympanometry

Acoustic impedancemetry hunosanganisira kukwanisa conductivity kuyerwa pashure mhepo nevezera kuchinja. Izvi zvinonzi tympanometry. The midziyo anoona kuchinja kupinda apo okuda kunowedzera mazana maviri millimeters mvura Mbiru richikwidibira pasi apa -400 millimeters.

Kupinda zvinoenderana sei kusiyana kumanikidzwa iri kwokunze auditory Canal uye pakati nzeve kukuru. The soro Kukosha indekisi iri pamutemo kana chete kumanikidzwa. Timpatogramme panguva ino zvinoratidzwa sezvo chemhando yepamusoro. Kukwidza kana achideredza kwokudzvinyirira anopa maitiro munyonga kuchinja. Kazhinji, chinofanira kutarisa akafanana tsamba "L". Vasingadzoreki kushanda pakati nzeve anochinja amplitude uye Maumbirwe tympanogram.

Kuongorora zviri kufefetedza kushanda auditory chubhu

Impedance - chii? Iyi nzira kumbonyatsoongorora kuongorora zviri auditory nhengo kuti rutapudzo kwayo kana kusarurama. Chimwe chikonzero chingava Eustachian chubhu dysfunction. chikonzero Its bindepinde adenoid zvinomera kukura, kuti cleavage ari zvakaoma mukanwa ndiro, oncological zvirwere mhino uye muromo, mucosal edema. dzimwe nguva vana vari kuchengetwa auditory chubhu patency nokuda rutapudzo pamusoro zvinyama elasticity uye mashandiro zvirwere velum tsandanyama.

Impedance Nzeve yokuziva patency pamusoro auditory chubhu rakakamurwa muzvikamu zvitatu:

1. Safety cheki. Anoitwa pa mumhepo kumanikidza mativi ose tympanic membrane.
2. Chiitiko Valsalva. The nasopharynx iri artificially akasika BP, uye murwere akakumbirwa kuvhara muromo uye mhuno. Chaiye patency mutopota soro kukoshesa timpatogramme (nhamba) rinobatana kufadza kumanikidzwa pfungwa.
3. Kuona Toynbee. Kugadzira kufefetedza mikana Eustachian sepombi yakaderera kumanikidzwa. Kuti aite izvi, murwere akakumbirwa Inwai, pashure nokuvhara muromo uye mhuno.

reflexometer

Kuti aone kana paine rutapudzo pamusoro stapedius tsandanyama (iye kuminyuka ari eardrum) pashure yokuwana mitinhimira vachishandisa acoustic impedancemetry. Sei muitiro? Nzeve ruzha kwechirwere zvakasiyana zvakanyanya uye vhoriyamu kutarisa acoustic dzepanguva.

In noutano vanhu, ichi dzepanguva chikumbaridzozve riri pakati makumi matanhatu kusvika makumi mapfumbamwe decibels. Changing makakatanwa ari tympanic Kamudzira akanyorwa kumativi ose, kunyange kana kurira zvinoitwa chete chete nzeve. dzepanguva Izvi zvinoreva Mhedziso.

Pane nzira mbiri kuita nzira ichi:

1. Ipsilateral, kana kurira voga kushumirwa munzeve, izvo zvinofanira kuongororwa.
2. Contralateral, kana ruzha chinotungamirwa kupinda nzeve, zvisina parizvino kuferefetwa.

Reflexometer kushandisa inzwi aine kakawanda mazana mashanu, chiuru, zviuru zviviri zvina Hertz, uye Broadband ruzha.

The chirwere kukosha nzira

Ko sei uchifanira impedancemetry? Chii uye nei richifanira kuitwa? Izvi zviri nyore kunzwisisa nzira rinobvumira murwere kuziva conductive uye sensorineural kusanzwa, pokukundwa rechinomwe kana kuti rechisere cranial tsinga, brainstem. Dzidza noninvasive, nyarara uye kuwanika chero murwere, pasinei nezera uye mufaro.

Chirwere dzekuziva nadzo sensorineural kusanzwa ndivo ezvinhu anotevera:

- acoustic dzepanguva iri pasika ruzha pamwero asingasviki makumi mashanu decibels;
- decibels kubva mashanu masere Reflex akanyorwa maererano kuwedzera inzwi;
- pashure masere decibels dzepanguva vasipo.

Acoustic reflexometer haapi kunoguma pamwe conductive kusanzwa, saka unogona kushandisa chikamu ichi kusiyanisa kubva sensorineural. The kukundwa of chiso etsinga rinopa dzepanguva pamusoro contralateral divi, asi kusavapo ake - kukunda. A nyaya kutyora auditory etsinga dzepanguva basa hapana kubva ane nzeve, kana kubva utano.

impedance-ph zvichiongororwa

Esophageal impedancemetry: chii? Izvi nzira nokuti Pakusarudza tsandanyama sunga pakati yegurokuro rusvingo, uye nepariri zvinwiwa uye magasi. Kwakavakirwa kuyera kurwisa pakati electrodes maviri, izvo kwakamboitwa dzakasiyana-siyana zvomudumbu chubhu. Panguva iyoyowo tsvakurudzo kunoyerwa acidity.

The nzira unobvumidza kuziva mhando reflux chirwere (acid, kwazvakarerekera kana alkaline), uye ayo mamiriro (gasi kana mvura). Chirwere dzekuziva nadzo Gerd (gastroezofagialnoreflyuksnoy chirwere) ndiko kuti kuderedza ph ari svikiro kusvika mana zvichidzika, asi zvichangobva kudzidzwa ndeyenhema dzidziso iyi. Naizvozvo, kukosha vakagamuchira zuva impedancemetry yegurokuro.

Nokuti murwere ichi chinotarisirwa kuburikidza mhino stylet, izvo akaronga pagungano wakaenzana penguva michina. mudziyo Izvi zvinobvumira kunyoresa esophageal peristalsis uye acidity kugutsikana rikawiramo izvo kubva mudumbu.
