Noma kunjalo, ipharamitha esemqoka esetshenziselwa ukuxilonga isimo senqubo yenhliziyo yisilinganiso senhliziyo (isilinganiso senhliziyo). Ngesikhathi esifanayo, leli pharamitha lishintsha futhi lixhomeke ngokugcwele esikhathini lapho ukuxilongwa kwenziwa khona.
Yiziphi izinqubo ze-HR ezinyathelweni zokuqala?
Ukuze unqume ukuphutha, uma uhlaziya umsebenzi wesimiso senhliziyo yengane engakazalwa, itafula lisetshenziselwa ukuthi isilinganiso senhliziyo yesisu senqunywe amasonto. Ukuqapha okukhethekile kubhalwa isikhathi lapho lokhu kutholakala khona kwenziwa khona. Lokhu kuchazwa ukuthi leli pharamitha lishintsha ngokushesha kangangokuthi ekupheleni nasekuqaleni kweviki elilodwa amagugu ahlukene angalungiswa. Isibonelo, ekuqaleni kweviki lesi-7, izinga lokushaya kwenhliziyo liyi-126 lokushaya ngomzuzu, futhi ekugcineni liyi-149. Ngeviki le-13 izinga lokushaya kwenhliziyo lingama-159 beats.
Inhlitiyo yenhliziyo ishintshe kanjani ku-2rd and 3rd trimesters?
Ukushaya kwenhliziyo, okuguqulwe ngamasonto okukhulelwa, kuqhutshwa izinguquko ku-2 trimester. Ngakho kusukela emavikini angu-12 ukuya kwangu-14 ngezinkomba ezijwayelekile ezithathwe izinsimbi eziyi-140-160 ngomzuzu. Inhliziyo enjalo ibonakala kuze kube sekupheleni kwenqubo yokuzalwa. Ukuphambene nalokhu noma okuphambene nalokho, ngokuvamile kubonisa ukuba khona kwephulwa. Ngesikhathi esifanayo, imbangela enkulu yokushintsha kwenhliziyo kunoma yisiphi isikhathi sokubeletha i-hypoxia yesisu. Ngokuvamile, kuholela ekwandeni kwenhliziyo, i-tachycardia. Ezimweni ezinzima zomoya we-oksijeni, kunesibindi se-bradycardia, okuwumphumela walokho okubizwa ngokuthi ukungenwa kwe-fetoplacental. Ezimweni ezinjalo, udokotela unquma ukuthi uzokwenzani okulandelayo: ukwenza ukubeletha ngaphambi kwesikhathi (uma kungenzeka futhi uvumele leli gama) noma ukugcina owesifazane, uzama ukusimamisa isimo sakhe.
Isilinganiso senhliziyo sihlolwe kanjani sekwephuzile?
Ukuhlolwa kwesilinganiso senhliziyo, esenziwa amasonto okukhulelwa, kwenziwa kamuva ngosizo lwe- CTG. Qala ngamasonto angu-32, bese uphinda le nqubo njalo ezinsukwini ezingu-14. Kanye nokulungiswa kwesilinganiso senhliziyo, ukulungiswa kwezicucu ze-uterine kanye nomsebenzi womsebenzi wengane kwenzeka. Yilezi zikhombisi ezicatshangelwayo uma zihlola isimo jikelele somntwana, kanye nokuhlola ukuthuthukiswa kwe-intrauterine.
Yini ebangela ushintsho ekutheni kwenhliziyo ye-fetal?
Kunezizathu eziningi zokwandisa izinga lokushaya kwenhliziyo. Leli qiniso licindezela inqubo yokuxilongwa, futhi ngezinye izikhathi akunakwenzeka ukusetha okuholela ekuthuthukiseni ukwephula. Noma kunjalo, akuyona njalo ushintsho kule nkomba kubangelwa ukuphulwa okwamanje. Ngakho, ukuphambuka kwezinga lenhliziyo kusuka kumkhuba kungaholela:
- izifo ezingapheliyo ezikhulelwe;
- ukuwohloka kwesimo sengqondo sengqondo somama okhulelwe;
- umsebenzi okwenyuka ngokomzimba.
Ngaphezu kwezici ezingenhla, ukwanda kwentengo yenhliziyo yengane kukhuthazwa ngumsebenzi ohamba ngokweqile wesifazane okhulelwe. Ngakho-ke, ngenkathi lesi sibonakaliso siphaphama kancane, futhi ngesikhathi sokuphumula inhliziyo yengane ishaya kancane kancane. Lezi zici nazo zicatshangelwa ekuxilongweni.
Ngakho-ke, isici esinjalo sokusebenza kwesimiso senhliziyo somntwana esibelethweni siyamfundisa futhi sisetshenziselwa ukuxilongwa ngezifo ngesikhathi esifanele. Ezimweni eziningi, kungenxa yenguquko kule parameter odokotela ababeka i-hypoxia ye-fetal, edinga ukulungiswa, kusukela Kamuva lokhu kuyathinta kakhulu ukuthuthukiswa komntwana wesisu.
