I-Doppler ultrasound

I-Doppler ultrasonography isebenzisa isiphumo se-Doppler ukuhlola ukuba ingaba izakhiwo (ezidla ngokuba ligazi)[32] ziyasingisa okanye zikude kwiprobe, kunye nesantya esinxulumeneyo. Ngokubala ukutshintshwa kwamaxesha omthamo othile wesampulu, umzekelo ukuhamba kwi-artery okanye ijethi yokuhamba kwegazi phezu kwevalve yentliziyo, isantya kunye nesalathiso sinokumiselwa kwaye sibonwe. Umbala weDoppler ngumlinganiselo wesantya ngokomlinganiselo wombala. Imifanekiso yeDoppler yombala idityaniswa ngokubanzi kunye nesikali esingwevu (imowudi ye-B) ukubonisa imifanekiso ephindwe kabini ye-ultrasonography.Usetyenziso lubandakanya:

I-Doppler echocardiography, ukusetyenziswa kwe-Doppler ultrasonography ukuvavanya intliziyo. I-echocardiogram inokuthi, ngaphakathi kwemida ethile, ivelise uvavanyo oluchanekileyo lwesikhokelo sokuhamba kwegazi kunye nesantya segazi kunye nezicubu zenhliziyo kuyo nayiphi na indawo engafanelekanga usebenzisa i-Doppler effect. Imilinganiselo yesantya ivumela ukuvavanywa kweendawo zevalvu yentliziyo kunye nomsebenzi, naluphi na unxibelelwano olungaqhelekanga phakathi kwecala lasekhohlo nelasekunene lentliziyo, nakuphi na ukuvuza kwegazi ngeevalvu (valvular regurgitation), ukubalwa kokuphuma kwentliziyo kunye nokubalwa komlinganiselo we-E/A[35] ] (umlinganiselo we-diastolic dysfunction). I-ultrasound eyomeleziweyo esebenzisa i-gas-ezaliswe yi-microbubble i-media eyahlukileyo ingasetyenziselwa ukuphucula isantya okanye enye imilinganiselo yonyango ehambelana nokuhamba.
I-Transcranial Doppler (TCD) kunye ne-transcranial color Doppler (TCCD), elinganisa isantya sokuhamba kwegazi kwimithambo yegazi yengqondo ngokugqithiswa (ngecranium). Zisetyenziswa njengeemvavanyo zokunceda ukuxilonga i-emboli, i-stenosis, i-vasospasm evela kwi-subarachnoid hemorrhage (ukuphuma kwegazi kwi-aneurysm ephukile), kunye nezinye iingxaki.
Iimonitha ze-Doppler foetal, nangona ngokuqhelekileyo zingekho ngokobugcisa -igraphy kodwa zivelisa isandi, sebenzisa i-Doppler effect ukubona ukubetha kwentliziyo yomntwana kukhathalelo lwangaphambi kokubeleka. Ezi zibanjwa ngesandla, kwaye ezinye iimodeli zikwabonisa izinga lokubetha kwentliziyo kwizingqi ngomzuzu (BPM). Ukusetyenziswa kweli sweni ngamanye amaxesha kwaziwa ngokuba yiDoppler auscultation. I-Doppler ye-feetal monitor idla ngokubizwa ngokuba yi-Doppler okanye i-fetal Doppler. Iimonitha ze-Doppler fetal zibonelela ngolwazi malunga nosana olufana nalolo olubonelelwa yi-fetus stethoscope.
