I-Doppler ye-fetus iyinsimbi egcinwe nge-ultrasound ebonakala njengomsakazo omncane ne-transducer ifakwe. Odokotela basebenzise ukulalela inhliziyo yentombazane engakazalwa. Kwabesifazane abaningi, ukushaya kwenhliziyo kwengane kufanele kubonakale ngeDoppler ngamasonto angu-12 okukhulelwa - ekupheleni kwekota yokuqala.
Kodwa-ke, kunokuhlukahluka komuntu ngamunye lapho inhliziyo izobonakala khona.
Abanye besifazane bangase bazwe ukushaya kwenhliziyo ngedivaysi yeDoppler emavikini angu-8, kanti abanye bangase bangakuzwa kuze kube sekupheleni kwamasonto angu-12. Ngenxa yalesi sizathu, odokotela abathile ngeke baqale ukuhlola ukushaya kwenhliziyo ngeDoppler kuze kube yilapho besifazane bekhulelwe amasonto angu-12.
Ukusebenzisa i-Doppler ekhaya
Uma ucabanga ukuqasha idivaysi yeDoppler yokusetshenziswa ekhaya, kungase kube ngcono ukulinda kuze kudokotela wakho athole ukushaya kwenhliziyo kwesinye sokuhlolwa kwakho kokubeletha ukuze wazi ukuthi kufanele kutholakale (futhi ungacela amathiphu indlela yokuthola ukushaya kwenhliziyo ngedivayisi yasekhaya).
Ukulalela ukushaya kwenhliziyo kwengane kungaba kokubili okuthakazelisayo nokukhathazeka-okunciphisa uma unomlando wokukhulelwa kwesisu . Ukuzwa ukushaya kwenhliziyo kuyisiqiniseko esikhulu, kodwa ukungayitholi kungase kukukhathaze - nakuba kungasho ukuthi kukhona okungalungile. Khumbula ukugcina iphuzu lokugcina engqondweni uma uhlola ukushaya kwenhliziyo ekhaya futhi ungakabi namaviki ayishumi nambili.
Futhi phawula ukuthi uma usu-trimester wesithathu, kufanele uqaphele amaphethini wokunyakaza komntanakho futhi uxhumane nodokotela wakho uma ubona ukwehlisa ukunyakaza . Ungathembeli ku-monitor ye-heartbeat ukuze uhlulele ukuthi ingane yakho ilungile.
Isaziso sokuqapha kusuka ku-FDA
I-Food and Drug Administration (FDA) ikhishwe isixwayiso kubomama abalindele ukusebenzisa amadivaysi e-Doppler ephathekayo ekhaya ngokuqapha.
Amadivaysi e-Doppler aphethwe ngesandla ashushungiswa ngokomthetho njenge "amadivaysi kadokotela," futhi, ngokusho kwe-FDA, "kufanele isetshenziswe kuphela, noma ngaphansi kokuqondiswa, ochwepheshe bezempilo."
Nakuba kungekho bufakazi bokuthi amadivaysi e-Doppler alimaza ingane ekhulayo, i-ultrasound ingakwazi ukushisa izicubu ezincane. "Uma umkhiqizo uthengwa phezu kwe-counter futhi usetshenziselwa ngaphandle kokubonisana nodokotela wezempilo wezempilo ozonakekela owesifazane okhulelwe, akukho ukuqondisisa ukuthi isetshenziswa kanjani. Futhi, kunenzuzo encane noma engekho yezokwelapha okulindelwe kusukela ekuvezweni," kusho u-Shahram Vaezy, Ph.D., unjiniyela wezokwelapha we-FDA. "Ngaphezu kwalokho, inani lezinhlelo noma ubude beseshini ekuskena isisu asilawulwa, futhi lokho kwandisa okungaba yingozi kumntwana futhi ekugcineni umama."
Ngaphezu kwalokho, kukhona ukukhathazeka ukuthi ezandleni ezingaqeqeshiwe zabomama abakhulelwe abangaqeqeshiwe abasebenzi bezokwelapha, abakwaDopplers basekhaya banganikeza umqondo wamanga wokuqinisekisa: Lapho ezwa lokho owesifazane akholelwa ukuthi uyisifo senhliziyo, angase aphuze ukufuna ukwelashwa lapho empeleni kuvunyelwe.
