When you have the doppler studies done, the blood flow is recorded in a wave pattern. The wave goes up and falls a little. If you have notching, the blood goes up, falls sharply and then flattens out. It shows that there's something impeding the bloodflow through the artery. Here's a link that shows what the notching looks like.

They are looking for something called "notching". You'd have to ask your doctor about the specific numbers as it relates to your case. But, I read that it's more accurate in first pregnancies and less accurate in subsequent pregnancies. Hopefully someone with the articles will post them for you soon.

I have an Avery, too! ;-)

Doppler artery ultrasound

So my MFM said at 22 weeks they'd do a doppler artery ultrasound and if things "looked good" I'd have a 1% chance of gettin pree and if they looked "bad" I'd have a 50% percent. Is this the uterine notching people are talking about? What is this really? What are they looking for? Where do these numbers come from? Are there any links anyone has for more information?

Thanks!
