Kuberekwa kwehupenyu hutsva chinhu chakavanzika chikuru. Nhasi, vanachiremba vane zvishandiso zvavo zvinovabvumira "kutarisa" mukati mehutano, uye asi isu tisati takaziva zvese zvisinganzwisisiki zvekusimudzirwa kwomunhu weramangwana, asi isu tinogona kutonga mamiriro echecheche, chaizvoizvo, chete nemoyo wekutengesa (mwoyo wekutengesa). Vanaamai vanouya vane shungu nekutya vanozviteerera ivo, nemwoyo unononoka, vanotarisira migumisiro ye ultrasound kana CTG - zvose zvakanaka nezvakakomba? Mitemo yekutsvakurudza, sekutonga, ine mitemo yakasiyana-siyana: mwoyo wemwana uri kuramba uchichinja, saka tsika dze fetal heart rate dzinogona kusiyana zvikuru nevhiki.
Fetal heart rate mukutanga kokutanga
Mwoyo wemukomana inoumbwa pavhiki 4-5 yekuzvitakura. Uye ikozvino pavhiki 6, fetal heartbeat inogona "kunzwika" nechitenderedzwa che ultrasound sensor. Munguva iyi, mwoyo nehutachiona hwemucheche hahuri kutora, saka mumutatu wekutanga kune mitemo ye fetal heart rate yevhiki , achibvumira chiremba kuti aone kufambisa uye chimiro checheche. Maitiro e fetal heart rate kwemavhiki anopiwa mutafura inotevera:
| Nguva yekuzvitakura, vhiki. | Nhamo ye mwoyo, ud./min. |
|---|---|
| 5 (kutanga kwechimiro chemoyo) | 80-85 |
| 6th | 103-126 |
| 7th | 126-149 |
| 8th | 149-172 |
| 9th | 175 (155-195) |
| 10 | 170 (161-179) |
| 11th | 165 (153-177) |
| 12th | 162 (150-174) |
| 13th | 159 (147-171) |
| 14th | 157 (146-168) |
Ndapota cherechedza kuti kubva pa5 kusvika kuma8 vhiki inosanganisira, HR inotanga vana pakutanga uye pakupera kwevhiki (mwoyo wekuwedzera kuwedzerwa) inopiwa, uye kubva pa9 vhiki yekutakura inowanzosvika pamwoyo uye kuvhiringidza kwavo kunopiwa. Semuenzaniso, fetal heart yakarova pamasvondo manomwe ichava 126 kurohwa paminiti pakutanga kwevhiki uye 149 kurohwa paminiti pakupedzisira. Uye pamasvondo gumi nemapfumbamwe, furo yemwoyo, pamusana, inofanirwa kuva 159 kurohwa paminiti, tsika dzakanaka dzichaonekwa kubva pa14 kusvika ku171 kurohwa paminiti.
Fetal heart rate mune yechipiri uye chechitatu katatu
Zvinotendwa kuti kubva pamasvondo gumi nemaviri ekuberekwa uye kusvika pakuberekwa kwomwoyo wemwana inowanzoita zviro 140-160 paminiti. Izvi zvinoreva kuti kutora kwomwoyo we fetal pamasvondo gumi nemasere, masvondo makumi maviri nemaviri, makumi matatu nemasvondo makumi mana makumi mana (40) anofanira kuramba akafanana. Kukanganisa mune rumwe rutivi kana chimwe chinoratidza kusafara kwomwana. Nekukurumidza (tachycardia) kana kudonha (bradycardia), mwoyo, chiremba, pakutanga, achafungidzira intrauterine hypoxia ye fetus. Tachycardia inoratidza unyoro oksijeni yekushaya mwana, iyo inoratidzika semugumisiro wekugara kwenguva yamai muimba yakanyanyisa kana pasina kufamba. Bradycardia inotaura nezve hypoxia yakasimba, inokonzerwa ne fetoplacental kusakwana. Muchiitiko ichi, kunyatsokurapa, uye dzimwe nguva kuendeswa kwechimbichimbi nechikamu chechiesarea (kana kwenguva refu chirwere chisina kushanda uye chimiro che fetus chiri kuramba chichiwedzera) chinodiwa.
Pamasvondo makumi matatu nemasere uye mwedzi wekupedzisira fetal heart inogona kutsanangurwa kushandisa cardiotocography (CTG). Pamwe pamwe nebasa remwoyo romwana, CTG inonyora zvinyorwa zvechibereko uye motokari yemwana. Pamuviri pakupera
Pane zvimwe zvinokonzera kukanganisa kwe fetal heart rhythm: chirwere chemukadzi ane pamuviri, kushungurudzika kwake kana kunetseka, kuita basa (somuenzaniso, gymnastics kana kufamba). Mukuwedzera, chirwere chemwoyo checheche chinoenderana nemutambo wake: panguva dzekumuka uye kufamba, mwoyo wekuwedzera unowedzera, uye panguva yokurara mwoyo muduku unorova zvishoma. Izvi zvinofanirwa kufungwa nezvazvo mukudzidza kwechimiro chemuviri we fetus.
