Impedance - He aha ka mea a pehea ua lawe mai?

I loko o ke ola mākou makaukau o hiki e mai ia: emi ma ka lohe, no ka mea, honi. I kekahi manawa ia ka hana nui i kakahiaka nui, i kekahi manawa - e aho ke aumoe, akā, somehow ka holo o kaua e ike i kekahi kauka. I kekahi o kēia mau poe akamai i - otolaryngologist. Ua ka oia i ka mea e maopopo i nā kumu o ka maʻi puʻuwai.

Impedancemetry: He aha ka mea?

Impedance - mea he vocal hana o kaʻike,, i kokua ho oholo i ka wahi a me ka ano o ka poho hālāwai hoʻolohe manaʻo. Me ia, e hiki ke kiʻi 'ike e pili ana i ke kūlana o ka auditory Tube, cochlea, waena pepeiao, e like me kā lākou innervating nā aʻalolo.

Kēia papa hana e leie aku e huai ae maʻi e like me perforation o ka eardrum, timpanoskleroz, hoʻopōʻino patency o ka auditory paipu, otitis Media, otosclerosis a me na mea e ae.

Acoustic impedancemetry ho 'akomi e kaha ako i acoustic conduction ma ka waena pepeiao ka wā hoʻololi i ka lewa kolamu puʻe a me ka hopena kani. Summary o ee iaaanu aey - he acoustic admittance, a conductivity o na hale a o ka pepeiao waho a me ka waena, a me ka hookani impedance.

tympanometry

Acoustic impedancemetry nā kani conductivity ana ma hope o ea puʻe loli. Keia ua kapa tympanometry. Ke i hoʻomākaukauʻia huai ae ka loli ma ka admittance ka wā o ka manaʻo koikoi maoli he elua haneri millimeters o ka wai kia ao, a hakumakuma ia ma lalo -400 millimeters.

Admittance hilinaʻi nui ma luna i ka nui o ka likeʻole ma waena o ka manaʻo koikoi i loko o ka mawaho auditory Canal a me ka waena pepeiao. I ka lani kiekie loa waiwai o kēia 'inideka ua heluʻia ka wā o ka ia puʻe. Timpatogramme ma keia wahi ua hoike like me ka lani kiekie loa piko. E hoohaunaele ana a ua hakumakuma i ka'aloʻahiʻa i hāʻawi mai i ke ano hālawa hoʻololi. Maʻamau, ka mea e nana e like me ka palapala "L". Hihia hoʻi hana o ka waena pepeiao EUIAaIN ka ikaika hawewe a me ke kinona o ka tympanogram.

Hoʻokolokolo 'ana o ka papa hoʻokomo ea o ka auditory Tube

Impedance - He aha ka mea? Kēia ʻaoʻao o ka hoʻokolokolo pono ninaninau o ka auditory hui, no kona ka ho'ēmiʻana a ei. Kekahi kumu paha e Eustachian Tube dysfunction. Kona kumu ano adenoid kanu ka ulu, ka cleavage o ka paʻakikī kīleo papa, oncological maʻi o ka ihu a me ka waha, mucosal edema. Keiki i kekahi manawa, malama auditory şarkı patency aie i ka ka ho'ēmiʻana o ka'aʻaʻa elasticity a me ka papa kāna hana velum nāʻiʻo.

Impedance o ka pepeiao, e hooholo i ka patency o ka auditory Tube ua maheleia i ekolu kahua o ka hoʻonaʻauao.

1. Maluhia o ka Lehulehu ponopono. Hana ma ka lewa puʻe ma na aoao a elua o ka tympanicʻili lahilahi.
2. Experience o Valsalva. Ke nasopharynx Ua artificially hana kiʻekiʻe ke koko, a me ka hoʻomanawanui ua noi e pani i ka waha a me ka ihu. Ma maʻamau patency paipu kiekie loa waiwai ma timpatogramme (piko) coincides me ka mea i kā mākou puʻe wahi.
3. Ka hoao ana Toynbee. Hoʻopunipuni hoʻokomo ea nā papaha Eustachian paipu ma haʻahaʻa puʻe. E hana i kēia, i ka hoʻomanawanui ua noi e lawe i ka inu, ma hope o panina o ka waha a me ka ihu.

reflexometer

I mea e nānā, ina paha he mea i ka ho'ēmiʻana o ka stapedius Muscle (wahine pulls ka eardrum) ma hope o waiū i ka mea kani-ka hoʻohana acoustic impedancemetry. Pehea o ke kaʻina hana? Pepeiao halulu hopena o kekahi pinepine 'a me ka leo, e kaha i ka acoustic reflex.

I ola kanaka, keia reflex paepae mea ma waena o kanaono i kanaiwa decibels. Hoʻololi i ka hoʻopilikia o ka tympanicʻili lahilahi, ua palapalaia ma na aoao elua, a hiki ina ke kani ua hana wale i loko o kekahi pepeiao. Kēia reflex pili ana i ka loa.

Aia mau aoao elua e hana i kēia kaʻina hana:

1. Ipsilateral, ka wā e mālama lākou i ke kaniʻana hoʻokaʻawale i loko o ka pepeiao, a pono e hoʻokolokolo.
2. Contralateral, ina o ka leo e olelo i loko o ka pepeiao, i mea ole a ianoiyuaa a ma lalo o ka hoʻokolokolo 'ana.

Reflexometer e hoʻohana kani me ka alapine (frequency) o ka elima haneri, he tausani,ʻelua tausani, a me nā tausani Hertz, a me ka hoʻoleleʻenehana kani.

Ke PalekanaEND_LINK waiwai o ke kaʻina hana

No ke aha la oe i pono ai impedancemetry? He aha ka mea, a no ke aha la ia e halihaliia oia iwaho? He kŘpa a na mea hana e leie aku ka hoʻomanawanui, e kuhikuhi i lawelawe a me ka lohe lilo sensorineural, i ke pio ana o ka hiku o ka ole walu cranial nā aʻalolo, brainstem. Hoʻopaʻa haʻawina noninvasive, painless a me ka loaʻa i kekahi hoomanawanui, nānā 'ole o ka makahiki a me ka pomaikai.

PalekanaEND_LINK 'Oihana no ka sensorineural lohe lilo ana i ka penei wahi, i hiki:

- acoustic reflex ua ike ia ma ka leo kiʻekiʻe o emi malalo o ke kanalima decibels;
- mai he kanalima i kanawalu decibels reflex kākau ma ka like loa no ka hōʻoi i ka leo;
- ma hope o kanawalu decibels reflex mea kahi e.

Acoustic reflexometer 'Aʻole e hāʻawi i nā hualoaʻa me ka lawelawe lohe poho, no laila, e hiki ke hoʻohana i kēia hiʻona e differentiate ia mai sensorineural. I ka make ana o ka lehalehu t nā aʻalolo e hoʻolako i ka reflex ma kaʻaoʻao contralateral, akā, i kona wa e kaawale aku - e eo ai. A hihia o ka 'aʻe' ana o ke aʻalolo reflex kuleana pili i auditory ole mai o ka loli ana o ka pepeiao, a mai ke ola.

impedance-pH ka mālamaʻana

Esophageal impedancemetry: He aha ka mea? Kēia hana no ka hoomaopopo ana i ka muscular contractions o ka esophagus pa, a hele ma ka mea fluids a me nā kinoea. Ua Ua nānā 'ana i ke ana ana i ka ia'ku ma waena o nā nā uila aʻa lolo elua, a i hoʻolauna i loko o nā wahi likeʻole o ka digestive Tube. I ka Ia manawa noiʻi ua anaia mai kaʻakika.

Ke kaʻina hana apono 'ia ka hoʻoholo' ana i ke 'ano o ka reflux maʻi (ʻakika,'ākilikai paha kona'ākilikai), a me kona' ole (kinoea make a me ka wai). PalekanaEND_LINK 'Oihana no ka GERD (gastroezofagialnoreflyuksnoy maʻi) mea e emi ai ka pH o ka meakino i ka eha a emi mai, akā, nā haʻawina hōʻoleʻia kāna i kēia kumumanaʻo. No laila, o ka nui i loaa i kela la impedancemetry esophagus.

No keia hoomanawanui ua lawelawe ma ka ihu stylet, a i hoonohonoho ma ka like wā mawaena detectors. Kēia mea e leie aku i ka inoa esophageal peristalsis a me kaʻakika maʻiʻo i moe i loko o ia, mai ka'ōpū.
