Chero ani mummai achayeuka nekusingaperi manzwiro ekushaya mwoyo kwe mwana wako, achiuya kubva kumashoni e ultrasound. Kubvira panguva ino apo mukadzi ane pamuviri asingabatanidzi anotanga kuteerera mutumbi wake, achiedza kubata zvinyorwa zvehupenyu mukati make.
Fetal heart test device
Kune nzira dzakawanda dzekutarisa kuonekwa uye nguva yakawanda yekurohwa kwemwoyo we fetal. Mushonga unonzi ultrasound machine unogona kubata fetal heartbeat pavhiki 6, kana iyo inosvika kudonhora 130 paminiti. Rimwe phonendoscope yezvokurapa inoita kuti zvikwanise kuverenga data idzi chete pamasvondo 16-17, apo rwiyo rwacho runowedzera kakawanda kupinda mumukadzi ane pamuviri. Izwi rine ruzivo rwekurohwa kwemoyo nemunhu ane ruzivo uye ane njere-gynecologist achabata, kuvhara nzeve kumudumbu wemukadzi. Uyewo, chigadzirwa chacho chinoshandiswa zvakanyanya echocardiograph, chinokubvumira kuongorora hurumende yega yega yemitsipa nemwoyo, pamwe nekuongorora kushanda kweropa kuderera mumatare ose. Kuongorora kubatwa kwemoyo we fetus asati aberekwa chiremba anobatsira cardiotocograph. Ndiye iye anoratidza zvokwadi yemabasa emuviri wemwana uye rwiyo rwekudzivirira kwehutachiona hwehutachiona. Inopa zviratidzo chaiyo zvekuberekwa kwechecheche ine oxygen uye basa rayo mukushanda kwebasa.
Fetal heart rate nemavhiki
Mune zvekurapa, pane humwe hutsika hwe fetal heart moyo yevhiki, kusanganisa chero kupi zvako kunofanira kukonzera kuchenjerera kuna amai uye chiremba anovatarisa. Heano mamwe mavara akafanana:
- Iyo fetal heart rate pamavhiki manomwe inowanzove inenge inenge 110-130 kurohwa paminiti;
- iyo fetal heartbeat pamasvondo gumi nemasere uye kusvika pakuguma kwegadziriro yekuita gumbo ndeye 140-160 kurohwa paminiti.
Chirongwa chekuita pamuviri wakarongwa chicharatidza fetal heartbeat pamasvondo makumi mana. Kukurukurirana kwe rhythm kune mitemo kuchabatsira kubvisa kutya kwevakadzi nekutya. Iyo fetus iri kutotamira mberi, inotora oksijeni yakawanda, maererano, uye mwoyo inorohwa nguva inowedzera. Mukuvapo kwehupi hupi hwehutano hwehupamuviri, iwe unogona kutevera fetal heartbeat pamasvondo makumi maviri uye zvose zvinotevera, kuitira kuti ubvise ngozi ye intrauterine rufu rwechecheche.
Iropitation ye fetus pamasvondo makumi maviri eve yakatosiyana zvakanyanya zvokuti inobvumira chiremba achicherechedza kuti ateerere kune mhere-mhere uye kuongorora mazwi emutsipa wemwoyo. Izvi zvinonzi auscultation. Kuonekwa kwezvinhu zvisina kuchena, kwakanyanyisa kana kusagadzikana kwepfungwa kunogona kuva chiratidzo checheki oxygen yekushaya nzara.
Nechisarudzo chakakodzera panguva yekunyora kubvunzurudzwa kwemukadzi, mukadzi ane pamuviri anotumirwa kune imwe nzira yekuita ultrasound, iyo inotarisa fetal heartbeat pavhiki 30, mamiriro ayo ose, nzvimbo, nezvimwewo. Iko panguva ino iyo kushandiswa kwekodhidhidiografia uye kujekesa nzvimbo chaiyo yemwoyo mumutsara wemwana kunogona.
Kana amai vane zvirwere zvakakomba zvehutano uye kukanganisa mukugadzirwa kwemwana, zvakakosha kutora fetal heart rate pavhiki 32, iyo inoshandiswa uchishandisa nzira yemaroto. Kweawa imwe nguva yezvipikiso zvemuviri wemwoyo wecheche yakanyorwa uye kusiyana kwayo panguva yehondo.
Mumavhiki ekupedzisira ekugadzirisa mwana anenge atove akakura uye anotora nzvimbo yose muchibereko. Iyo motokari inoderera, inoratidzika kuunganidza simba rinodiwa pakuzvarwa. An ultrasound ye fetal heartbeat pamasvondo makumi matatu nemasere icharatidza zvimwe kuderera mumagetsi ekuputika, izvo zvinowanzoitika panguva iyi.
Pakupera kwekuita pamuviri, chibereko chinenge chiri mu tonus, chinogona kukanganisa kugoverwa kweokisijeni kumwana. Hazvina kufanira kufungisisa fetal heart rate pavhiki 39, sezvo kuberekwa kwaswedera pedyo uye kuongororwa kwemamiriro ayo kuchava ruzivo rwakakosha kune chigadzirwa chezvipatara.
Chengetedza moyo wevhiki kwemavhiki chete kune vakadzi vane dambudziko rakadaro rekuvhiringidza gestation.
