Fetal heart rate

Mwoyo ndiyo imwe yekutanga kutanga basa rayo mumuviri wevanhu vanobva kumunhu. Anogogodza anogona kunzwisiswa ne ultrasound mushure mevhiki yechishanu yekuzvitakura, kana pavhiki yechitatu yekuberekwa kwemukomana. Chimiro uye nguva yakawanda yekutema mucheche inogona kutaura zvakawanda pamusoro pekuti mwana ari kukura sei, zvose zvakanaka kana kune zvimwe zvinetso.

Ko fetal heart rate yakatarwa sei?

Pazvikamu zvose zvepamuviri, vanachiremba vanoshandisa nzira dzakasiyana dzekuongorora basa remwoyo:

1. Pakupedzisira nguva inogona kuitika, kubatwa kwemwoyo kwemuviri kunobatsira nemusana we-ultrasound sensal, mumasvondo matanhatu kusvika pakuberekwa zvakakwana kuti uite tsika yekushandura ultrasound kuburikidza nekunze kwemadziro emadziro.
2. Inenge kubva mavhiki makumi maviri nemaviri chiremba anotanga kuteerera basa remwoyo ne stethoscope.
3. Mumavhiki makumi maviri nemaviri ekuberekwa, cardiotocography yaitwa.

Kupindirana kwema fetus nevhiki - chidimbu

Zvinotendwa kuti chirwere chinowanikwa chema fetus chinopfuura kaviri kupfuura icho chemai vake remangwana. Zvisinei, izvi hazvisi chokwadi zvachose: mumatangiro ekutanga ekudzivirira hutano hwemwoyo hwemucheche hunogara huchichinja. Saka, somuenzaniso, pamwe nenguva yevhiki masere, mwoyo inorova pamhanya we 110-130 kurova paminiti. Iyo palpitation ye fetus pamasvondo 9 ndeye 170-190 kurohwa paminiti. Muchikamu chechipiri nechechitatu, moyo unorova nehuwandu hwemasvondo: pamasvondo makumi maviri namasere nemaviri makumi matatu nemakumi matatu (fetal heart rate) ichave 140-160 kurova paminiti.

Kuyera kwemwoyo muvana - kusakosha

Zvinosuruvarisa, mubasa remwoyo muduku zvishoma nezvishoma kukanganisa kunoitika, zvichiratidza dambudziko rinogona kuitika muupenyu hwechecheche. Kana pakutanga, kana mazamu akazosvika kureba 8 mm, hapana marpitation, zvino izvi zvinogona kuratidza kuberekwa kwechando. Muchiitiko ichi, kazhinji kechipiri ultrasound inorayirwa, mushure mokunge chirwere chekupedzisira chinogadzirwa.

Tachycardia, kana kuti mapapiro emwoyo, mumucheche anokwanisa kutaura pamusoro peprauterine fetal hypoxia (kana amai vane ramangwana vane chirwere chokushaya simba anemia kana kuti yakareba mune zvakashata nzvimbo). Mukuwedzera, kazhinji kacho kuora mwoyo mumwana kunowanzoitika panguva dzekushanda kwakasimba kana panguva yekuita muviri weamai vari mberi.

Kushaya mwoyo uye kushaya mwoyo mukati memucheche (bradycardia) kunoratidza zvinetso zvinotevera:

• Indrauterine kwenguva refu hypoxia;
• kushandura kusagadzikana;
• kutaurirana kwakasimba kwe fetus;
• zhinji kana mvura shoma.

Chero kusanganisa kunobva kuchimiro kunofungidzirwa nachiremba sechiratidzo pamusoro pekusafara kwevana uye zvinonyanya kuratidza kuongororwa kwakawedzerwa, pamusana pekuti achasarudza kurapa kwakakwana.
