Nhengo ye fetus ndiyo chiratidzo chinonyanya kukosha chekuvandudza nekubudirira kwomwana. Zvichienderana nehupo hwahwo kana kusavapo pamatambo ekutanga ekudzivirira, zvinoguma kana kutakura kuripo kana kuti kune pamuviri wakafa. Basa rinokosha rinowedzerwa nemoyo wemazwi embryo, iyo inowanzofanira kuva mukati ma 110-200 kurova paminiti.
Ndezvipi zvinokwanisika kunzwa fetal heartbeat yekutanga?
Mwoyo wemukomana unoiswa pavhiki yechina yekuzvitakura. Pakutanga inoratidzika sehombodo. Uye ikozvino muvhiki yechishanu fetus inotanga kuora mwoyo - mwoyo wake unotanga kuputika. Nevhiki rechisere-yepfumbamwe mushure mekuberekwa, mwoyo uri kutotanga kuva madiki mana, zvakadai sokuti zvichave muhupenyu hwomwana asati aberekwa.
Mumazamu okutanga ekudzivirira, fetal heartbeat inogona kuonekwa nekubatsirwa kwe ultrasound. Kupindirana kwema fetus pa ultrasound muchidzidzo chekutengesa kunogona kuonekwa mushure mevhiki yechishanu kana yechitanhatu yekuzvitakura. Kamwe gare gare - mugore rechitanhatu-rechinomwe, palpitation ye fetus inonzwika uye ine transabdominal ultrasound.
Fetal heart rate
Kubva panguva yehutachiwana kunobva pane zvinobaya moyo we fetus. Muchikamu chekutanga chemitima yemwoyo (mwoyo wevhesi) we embryo inobva 110-130 kusvika 170-190 kurohwa paminiti. Iko kushandurwa kwekutanga kwekutatu kunobatanidzwa nekuvandudzika kwehutachiona hwehutachiona hwomukomana.
Kana iyo fetus ine chido chemoyo pasi pe 85-100 kana kupfuura vanokwana 200 paminiti mumutatu wekutanga, izvi zvinoratidza kusagadzikana maitiro. Izvi zvinoda kutora matanho ekubvisa zvikonzero zvekuchinja mumoyo wekuraira. Kuvepo kwekushaya kwepfungwa, apo fetus inenge yasvika pakusvika kwema 8 mm, inoratidza kubata kusina kukura. Muchiitiko ichi, ultrasound inodzokorora mushure mevhiki uye migumisiro inotorwa mberi.
Muchikamu chechipiri uye chechitatu, inhara yeH HR is 140-160 yakarova paminiti. Icho chidimbu chinofanira kunge chiine rhythmic.
Ndezvipi zvimwe zvinoteerera kushaya mwoyo kwemucheche?
Auscultation imwe nzira yekuongorora basa romwoyo wemwana muchibereko. Panguva imwecheteyo, kubatwa kwemwoyo kwema fetus kunoteererwa nekombiyamu yakakosha yekuteerera mwoyo (obstetric stethoscope). Kubva kune stethoscope inowanzogadzirwa, chipetric ine chando chikuru. Ndiro chiremba wake uyo anoshandisa mukadzi kumudumbu, uye kune rumwe rutivi rwehuputi anoshandisa nzeve yake.
Iyi nzira inowanzoshandiswa panguva yekuzvitakura uye panguva yekuberekwa. Yeuka kuti paunogamuchirwa kupi zvako mune zvevakadzi kubvunzurudza mudumbu wako chiremba anoshandisa iyi tubula tubule, kakawanda inogadzirwa nematanda.
Nenzira ye fetal heartbeat, yakarongedzwa kuburikidza ne stethoscope inopinza, chiremba anoita sarudzo yemucheche. Sezvo nguva yekuita mimba inowedzera, kupesana kwemoyo kunonzwika zvakajeka uye zvakajeka.
Kurongedza kwemucheche pamba
Kusvika iye zvino, imwe nzira yakagadzirwa kuti vabereki vekupedzisira vanogona kunakidzwa nemanzwiro emwoyo we mwana asati aberekwa pamba. Kuti uite izvi, iwe unoda kutenga inotakura ultrasonic Doppler mwoyo moyo we detector.
Iyo detector inogona kushamwaridzana nekombiyuta uye kunyora inzwi rekurova mwoyo. Ichi chichava chinyorwa chakasiyana-siyana chinyorwa, icho, zvakare, chinogona kutumirwa ne-e-mail kune chero kona yenyika (kana, somuenzaniso, baba vomwana vari kure nemudzimai wake ane pamuviri nekuda kwemamiriro ezvinhu). Izvi zvigadzirwa mumakore achangopfuura zvave zvakakurumbira zvikuru nekuda kwekusununguka kwekushandisa uye chibereko chinonakidza chebasa ravo.
