Fetus kwemwoyo: ndozvakajairwa uye kutsauka

Fetus kwemwoyo kunoratidza kukura upenyu hutsva. Kuti inechirevo utano mwana (mumuviri uye mupfungwa), manzwiro ake panguva. Naizvozvo, panguva pamuviri, vanachiremba uye vabereki vari kubhadhara ngwariro chaiyo nyaya iyi.

Kwemwoyo yavo specificity - nechiidzo mamiriro mwana. Mwoyo anovandudza refu chaizvo nguva uye ane zvakawanda kunzwisisa chivakwa pane zvose dzimwe nhengo. Rinotanga kuumbika vakapoteredza 4th vhiki pamuviri uye ari negomba chubhu, izvo rechishanu vhiki kare kuonekwa maronda vokutanga, uye kubudikidza wechipfumbamwe ayo mamiriro dzinotanga kufanana nemamiriro mwoyo zera. Asi muviri uyu mwana, ari mudumbu, zvichiri zvakasiyana zvatinosiita iye akacherechedza kuvapo mugomba pakati kurudyi uye rworuboshwe atrium uye arterial chokubuda. Chokwadi chokuti mudumbu havagoni kufema pachavo, nokuti mamiriro akadaro anobatsira okisijeni aibuda kune nhengo dzose mwana.

Child kwemwoyo - ndicho chikuru hunhu waro chinhanho. Kana runouya paminiti asingasviki 86-100, kana anopfuura 200 - iri chiratidzo chokushushikana. Kana mwana runosvika embryo kukura 8 mm uye mwoyo haagoni kunzwika, ipapo, zvichida, non-zvimwe pamuviri. Naizvozvo, ndichishanyira gayinakorojisiti, nguva dzose kuziva sei mwoyo anorova panguva mbudzana dzako.

Dzimwe nguva fetus kurova kwehana, mwero izvo kunoenderana nenguva pamuviri zvingava zvishoma nokuda waivako vakaisa placental insufficiency kana fetus hypoxia. Dzimwe mumugariro kunoitika apo pane breech mharidzo yacho mudumbu.

Characteristically, dzakanga gestational zera kupfuura kunzwa zvakajeka heartbeats. On yokuongorora, chiremba nguva achaongorora chakarurama ichi. Fetus kwemwoyo Anonzwa auskultatsionnoy kushandisa nzira (nzira iyi ndiyo nyore uye nyore kushandisa): obstetric stethoscope rinoshandiswa mudumbu kusvikira apo anenge iri mwoyo. Saka, muna cephalic mharidzo nzwisa inoitwa kana kuruboshwe kana kurudyi nechepazasi guvhu. It zvinoenderana apo mbudzana vakadzoka. Kana nzvimbo mwana muchinjikwa, mwoyo zvakanakisisa vanzwa guvhu pamwero. Breech mwoyo anorova kunonzwiwa kwazvo zvakajeka kana stethoscope riri kumusoro muviri.

In tanga pamuviri kudzora chakarurama ichi rinoitwa chete tichibatsirwa Ultrasound. Mune trimester pamuviri yokutanga mumwoyo mwero (kwemwoyo) haachinji. Chete ipapo kakawanda anotanga kuwedzera. Kusvikira vhiki wechisere mwero mwoyo kurwiswa havafaniri kupfuudza 130 anorova. Pamasvondo 9-10 nomwoyo exchange anenge 180-190, uye kubva rechi11 uye pamberi kukurukura kwemwoyo ari mudumbu kunofanira kubva 140 kusvika 160 anorova paminiti.

At akazotevera zvokukura nokuchinja zviratidzi kunoenderana webasa mwana ari mudumbu uye kubva mutoro izvo anoisa pamusoro hadzi muviri (zvirwere, tembiricha (zvikuru kutonhora kana kupisa)). Kana pane kushayikwa okisijeni, mwoyo mwero kuwedzera kusvika 160, uye ipapo, nekusiyana, ipfupi kuti kurohwa 120.

Zvakakodzera kukura mwoyo ruzha vanofanira kuva mutinhimira uye tsime, zvakajeka nzwisa. Arrhythmia kuchengetwa avo vana vakambova mwoyo vakaremara kana fetus hypoxia.
