A fetal Doppler iyi inoshandiswa nemaoko ultrasound device inoratidzika sekadhiyo duku ine transducer yakaiswa. Vanachiremba vanoshandisa iyo kuti vateerere kune mwoyo wekare-ku-kuberekwa kwemoyo wemwana. Kune vakadzi vazhinji, kurwadziwa kwomwoyo kwevana vavo kunofanira kuonekwa kuburikidza neDoppler nemavhiki gumi nemaviri ekuzvitakura - kuguma kwekutanga kwemutatu.
Zvisinei, pane zvakawanda zvakasiyana-siyana mumunhu kana mwoyo uchingowanikwa.
Vamwe vakadzi vanogona kunzwa kushaya mwoyo nemutambo weDoppler mushure memavhiki masere, asi vamwe vangave vasinganzwi kusvika kusvika kwevhiki 12. Nokuda kwechikonzero ichi, vamwe vanachiremba havangatotanga kutarisa kubata mwoyo neDoppler device kusvikira vakadzi vane masvondo gumi nemaviri vasikana.
Kushandisa Doppler Pamba
Kana uri kufungidzira kubhadhara Doppler device yekushandisa kumba, zvingava zvakanaka kumirira kusvikira chiremba wako awana kushaya mwoyo pane imwe yekutarisa kwako kwepabonde kuitira kuti uve nechokwadi chokuti inofanira kuonekwa (uye iwe unogona kukumbira mazano pane nzira yekuwana kushaya mwoyo nemutambo wemusha).
Kuteerera nokuda kwomwoyo wemwana kunogona kuva kunofadza uye kushungurudza-kunokonzera kana iwe une nhoroondo yekuenda pamuviri . Kunzwa kuora mwoyo kunonyaradza, asi kusazviona kungaita kuti unzwe uchitya-kunyange zvazvo zvisingatauri kuti pane chakaipa. Yeuka kuchengeta pfungwa yekupedzisira mupfungwa kana uri kutarisa kushaya mwoyo pamusha uye iwe hausati wava nemavhiki 12 pamwe chete.
Uyewo ona kuti kana iwe uri mumutatu wechitatu, iwe unofanira kutora maitiro ekufambisa kwemwana wako uye taura nachiremba wako kana ukacherechedza kuderedza kufamba . Usavimba nemoyo unotarisa kuti uone kana mwana wako akarurama.
Nyaya yekuchenjera kubva kuDefA
Zvokudya uye Drug Administration (FDA) zvakabudisa nyevero kune vanaamai vanotarisira kushandisa zvishandiso zveDoppler zvinyorwa pamusha nekuchenjerera.
Mafashoni eDoppler emafashoni anotengeswa zviri pamutemo se "maikirwo emishonga," uye, maererano neDFA, "inofanira kushandiswa chete, kana pasi pekutarisirwa, unyanzvi hwehutano."
Kunyange zvazvo pasina humwe uchapupu hwekuti Doppler zvigadzirwa zvinokonzera kukura mwana, ultrasound inogona kupisa zvinyuchi zvishoma. "Kana chigadzirwa chacho chakatengwa pamusoro pekambani uye kushandiswa pasina kubvunzurudzwa nemudzidzisi wehutano anotarisira mukadzi ane pamuviri, hapana kutarisa kwekuti chigadzirwa chacho chinoshandiswa sei. Uyewo, pane zvishoma kana pasina mushonga unobatsira unotarisirwa kubva pakuratidza," "anodaro Shahram Vaezy, Ph.D., muInjiniya yeAIDS. "Uyezve, nhamba yezvikamu kana urefu hwechikamu chekuongorora kuberecheche hachidzorwi, uye izvo zvinowedzera zvinogona kukuvara kumucheche uye pakupedzisira amai."
Mukuwedzera, pane kushungurudza kuti mumaoko asina kudzidziswa aamai vane pamuviri vasina kuongororwa vashandi vezvokurapa, imba Dopplers inogona kupa pfungwa dzisina kunyatsosimbiswa: Paanonzwa izvo mukadzi anotenda kuva chido chemoyo, anogona kunonoka kutsvaga kurapwa apo inonyatsobvumirwa.
