I-Doppler ye-fetal iyisistim e-hands ultrasound ebonakalayo ekhangeleka njengowomnxeba omncinci kunye ne-transducer eqhotyoshelweyo. Oogqirha basebenzise ukuphulaphula intliziyo yesana. Kwabaninzi abasetyhini, intliziyo yesana kufuneka ibonakale ngeDoppler ngeeveki ezili-12 zokukhulelwa -ekupheleni kwekota yokuqala.
Nangona kunjalo, kukho ukuhlukahluka komntu ngamnye xa intliziyo iza kubonakala.
Abanye abesifazana banokuva i-heartbeat nge-Doppler idivayisi emva kweveki eziyi-8, ngelixa abanye bengenakukuva de ukuya kwiiveki ezili-12. Ngesi sizathu, abanye oogqirha abanakuze baqale ukukhangela i-heartbeat nge-Doppler idivaysi kude kubekho amabhinqa angama-12 ekhulelwe.
Ukusebenzisa iDoppler ekhaya
Ukuba ucinga ukuqasha i-Doppler ifowuni yokusetyenziswa kwekhaya, kungcono ukuba ulinde de ugqirha wakho ufumene i-heartbeat kwelinye iliso lakho lokuhlola kwangaphambi kokubeletha ukuze wazi ngokuqinisekileyo ukuba kufuneka zibonwe (kwaye unokucela iingcebiso malunga indlela yokufumana intliziyo ngecebo lendlu).
Ukuphulaphula intliziyo yentsana inokuba yinto enomdla kunye nokuxhalabisa xa unembali yokukhulelwa kwesisu . Ukuva intliziyo kuyisiqinisekiso esikhulu, kodwa ukungafumani nto kunokukwenza ube nexhala-nangona oko akuthethi ukuba kukho into ephosakeleyo. Khumbula ukugcina ingongoma engqondweni xa uhlola i-heartbeat ekhaya kwaye awukho iiveki ezili-12.
Kwakhona qaphela ukuba xa usesithathu kwi-trimester, kufuneka uqaphele indlela yokuhamba yentsana yakho kwaye uqhagamshelane nogqirha wakho ukuba uyaphawula ukunciphisa ukunyakaza . Musa ukuzithemba kwesosivivinywa senhliziyo ukugweba ukuba umntwana wakho ulungile.
Isaziso sokulumkela kwi-FDA
Ulawulo lwezoKutya kunye noTywala (FDA) lukhuphe isilumkiso kubamama abalindele ukusebenzisa ii-Doppler eziphathekayo kwikhaya ngokuqapha.
Izixhobo zeDoppler eziphathekayo zithengiswa ngokusemthethweni njenge "zixhobo zogunyaziso," kwaye, ngokwe-FDA, "kufuneka isetyenziswe kuphela, okanye phantsi kweliso lwezonyango."
Nangona kungekho bubungqina bokuba iifowuni zeDoppler zilimaza umntwana osakhulayo, i-ultrasound inokutshisa iishubhu ezincinane. "Xa umthengi uthengiwe kwi-counter kwaye usetyenziswe ngaphandle kokubonisana nomsebenzi wezonyango ojongene nokunyamekela umfazi okhulelweyo, akukho nongamele indlela esi sixhobo ngayo. U-Shahram Vaezy, Ph.D., unjiniyela we-FDA wezilwanyana. Ngaphezu koko, inani leeseshoni okanye ubude beseshoni ekutshekeni umntwana aluyi kulawulwa, kwaye okwandisa inokulimaza kumntwana kwaye ekugqibeleni unina. "
Ukongezelela, kukho ukukhathazeka ukuba kwizandla ezingaqeqeshiweyo zoomama abangaqeqeshelwa ngabasebenzi bezonyango, abadibanisi basekhaya banganikezela ngengqiqo yokuqinisekisa: Xa beva oko umfazi ekholelwa ukuba yintliziyo, unokulibazisa ukufumana unyango xa ngokwenene kuqinisekisiwe.
