... for echocardiographic parameters during the early transitional circulation in term infants. Methods: Two-dimensional, M-mode, pulsed and color flow Doppler echocardiography was used to assess healthy term infants in the first 4 h of life. Left and right ventricular outputs (LVO and RVO) and myocardial performance...

...Gerhard Jorch; Thomas Huster; Heike Rabe To investigate changes of intracerebral blood flow velocity correlated to different behavioural states, pulsed Doppler measurements were performed on anterior cerebral artery in 12 preterm and term neonates under polygraphic recordings and in view...

...Giuseppe Rizzo; Domenico Arduini; Carlo Romanini; Salvatore Mancuso In order to assess whether maternal hyperoxygenation induces modifications of Doppler-measured velocity waveforms across atrioventricular valves, 15 healthy and 15 growth-retarded fetuses were studied in basal conditions and during...

...Tonse N.K. Raju; Margaret Go; James C. Ryva; David J. Schmidt Using a commercial pulsed Doppler (PD) system we measured commoncarotid artery (CCA) flow velocities in 19 healthy and 6 stable preterm infants and computed volume flow rates based on the time-averaged flow velocities and vessel diameter...

... by umbilical-placental vascular insufficiency. A group of women (n = 13) with abnormal Doppler umbilical artery flow velocimetry and a group of control women (n = 11) with uncomplicated term pregnancies and normal umbilical artery flow velocity waveforms were studied. In each woman, inhibin A and inhibin B...
