Re: Fetal umbilical vein doppler againFrom: Daniel Margulies (danymarg@fibertel.com.ar)Sun Mar 30 20:04:24 2003
both the venous and the arterial waveforms are affected by fetal breathing, Probably it would be more evident if the filter was lower and the speed higher NDM 2003
> ----- Original Message ----- It looks to me like the arterial wave is affected by the breathing. Can't tell if it is fetal or maternal breathing. Allen
> ----- Original Message ----- Thanks dear Udaya, and all Why should fetal venous flow be affected by maternal breating........? movement artefact If movement causes these why hasn't it affected arterial flow in my case ? please see below againfor pics. Let's try geting fetal umbilical vessels doppler with wider gate to include artery + vein.........during maternal respiration (both held and active), & during fetal breathing movement to see the spectrum. Does Latha and somebody have references for fetal umbilical vein doppler, and how it is affected by fetal and maternal breathing? thanks fazeel Resending for you, Fazeel This picture was taken entirely for Fazeel's benefit. I was watching her breath and could easily see the venous flow change (indulate) with maternal breathing. The peaks of the arterial waveforms show a mild reduction in height too(coinciding with the dip in venous flow). ...Udayakumar The peaks of arterial waveforms show a mild reduction coinciding with the venous nadir. ...Udayakumar "Dr. Fazeel" wrote:

Does the venous flow indicate, undulations due to fetal breathing movements?? or is it something else? Please also describe the arterial flow characteristics.<?XML:NAMESPACE PREFIX = O /> fazeel ____________________________________________________ IncrediMail - Email has finally evolved - Click Here ____________________________________________________
