Shenzhen Bestman Instrument Co., Ltd. has been devoting to research, manufacturing and distribution of medical instruments We have a series of products: BF series Fetal Doppler, BV series Vascular Doppler, BFW series Medical Blood and Infusion Warmer,BFM
The Doppler umbilical systolic-diastolic (S-D) ratio decreased with gestation in the negative group, suggesting continuing placental growth and vascular expansion, whereas the S-D ratio increased in the positive group (P < 0.001), indicative of vascular obliteration. We suggest that the positive ...

Doppler meas- urements were reproducible and carried out by the same ultrasound physician three times. We chose the ultrasound parameters (PI, RI, S/D and Vm) to detect fetal MCA and UA blood flow during pregnancy. PI, was calculated using the following formula: PI ¼ Vs À Vd Vm ...
50,51 The sympathetic efferent arm triggers intense peripheral vasoconstriction across multiple vascular beds,48,52 which supports arterial pressure by offsetting the immediate fall in cardiac output associated with the deceleration. The net effect is either the maintenance of or an increase in the ...
sobrevida del feto bomba entre las dos técnicas (84% v/s 70%) sin embargo, la tasa de éxito clínico, definido como sobrevida después de la interrupción completa del flujo sanguíneo y parto después de las 32 semanas, fue mayor en la ablación vascular intrafetal (77% v/s 50%)...
(2003) showed that intrahepatic portal veins developed a greater contractile force in response to catecholamines than the vascular rings of the isthmic portion of the DV [27]. Since fetal hypoxia causes a sharp increase in plasma catecholamine levels, it is possible that the increased DV flow ...
Objectives To compare fetal pulmonary artery Doppler parameters between pregnant women with asthma and healthy pregnant women. Methods This prospective, cross-sectional study was conducted on 50 pregnant women diagnosed with asthma and 61 healthy pregnan
