Pamasvondo makumi matatu nematatu, kutora kwako kutotanga kusvika nokukurumidza. Somuenzaniso, vanhu vazhinji vanocherechedza kuti nhamba yekushungurudzika yava kunyanya kudarika. Izvi hazvishamisi, nokuti mwana anoramba achikura, uye huwandu hweamniotic fluid huchiderera zvishoma nezvishoma, izvo zvinotungamirira kushoma kuderera kwe fetus. Kana wapedza ultrasound pamasvondo 32-33 ekuzvitakura uye uchitarisisa zvigumisiro nemagariro, iwe unogona kuona kuti zvinogona kuitika sei uye kutora matanho akakwana. Zvinofanira kuonekwa kuti panguva ino mwana atova akakwana, saka kunyange kuberekwa nguva isati yasvika haisi ngozi kune hupenyu hwake.
Fetal condition
Iyo ultrasound ye fetus mumasvondo makumi matatu makumi matatu nematatu inotova inopa mufananidzo wakakwana wehutano hwemwana, kuvapo kwehupi hupi hwehutachiona kana hunoipa mumusangano. Kana zvakange zvisingakwanisi kugona zvepabonde, kuongorora kwe ultrasound panguva ino kuchapa mhinduro inokwana 100% yakavimbika. Panguva imwe chete, kana chiremba nokuda kwechimwe chikonzero chakanga chisingagoni kugadzirisa hutano hwemwana, saka kazhinji kacho kune vabereki munguva yemberi izvi zvicharamba zvisinganzwisisiki kusvikira kuberekwa. Ichokwadi ndechekuti kune nzvimbo shomanana dzekufamba kwechecheche, saka hazvigoneki kuti achakwanisa kupfuurira.
Kubva pane data ultrasound pamasvondo makumi matatu nemaviri, zuva rekuuya kwekuuya kunonyatsotsanangurwa. Mukuwedzera, chiremba anogadza nzvimbo ye fetus mubereki, mukana wekunyangarika tambo yembilical uye unosarudza pamusoro pezvinogona nzira yekuendesa.

Kuwedzera kwehuwandu kwegore iri rekuzvitakura kune 300 g kwevhiki, uye fetus iyo inosvika 2 kg. Chimiro chekurema kwe fetus panguva ino ndeye 1800 kusvika 2550. Pakati pemimwe mhinduro inogona kuwanikwa pa ultrasound:
- kureba kwechibereko (chimiro 35-45 cm);
- biparietal size (norm 75-90 mm);
- ukuru hwema frontal-occipital (inowanzo 101-113 mm);

- pfupa remumhino (mumiririri 9-14 mm).
Zvakakosha kuziva kuti mhuka imwe neimwe ine maitiro ake, naizvozvo kusarura kusingafaniri kutyisa amai vanotarisira. Mukuwedzera, zvigumisiro zvedzidzo zve ultrasound zvingangove zvedzinza uye dzine imwe mhosho. Kuongorora zvikwangwani zve ultrasound zvinofanira kungova chiremba wekuenda-iye chete nyanzvi yekodzero ane kodzero yekutora mhedziso chero ipi zvayo nekuita zvisarudzo pamusoro pekurapwa kana kusununguka.
