How to Determine Blood Flow Direction with Ultrasound and Doppler

[@senaityohannes7515]

It took me very long time to understand this part of vascular, I almost got to the point giving up, because I get very frustrated that didn’t get it. Thank God you made it Simple. God bless you,

[@zangounette]

thank you so much i was thinking i was dumb after still not being sure in which direction it goes, this method works well

[@solelylinny1710]

OMG! You are a lifesaver. Please make more RVT videos.

[@amusicveteran]

It has taken me long time to try and understand this and you made it crystal clear in one video. I thank you sincerely for sharing your knowledge.

My Goodness!!! Never have I seen this explained any better!!! Thank you so much for you knowledge and especially sharing it with us. Thank you and God bless. 🙏🏽 I hope and I look forward to more videos. 😌👍🏽 You really are a Pro!!!

[@prisaberrysaravia3635]

due to covid 19, all our classes were moved online and ofc it was while we were learning doppler and hemodynamics.... thank you so much!! i finally understand.

[@chaltimepass]

pls make more videos. basics taught in very lucid and clear way!

Perfectly understandable! Great educational info to help understand this concept. I’ve read & watched so many different ways to explain this & by far this is the most beneficially comprehensive vid. Thank you!!!

[@RessaMichelle]

At time stamp 8:48 I can't seem to understand how tie ICA is considered antegrade based off of the specifications mentioned.

[@drmichaelguirguis]

It's awesome, many thanks. I was also wondering about how to determine the steering angle, can you help with that?

[@behindtheknifethesurgerypo4986]

Seriously amazing video! I have watched videos by two different professional courses on this, and this is much much better. Saving me before my RPVI. Thank you!!

[@enriklarsson3041]

Good evening, excellent video!!!! I have a doubt, sorry for my english. For the case at minute 15:20, the Femoral Artery. If the transducer orientation points towards the patient's head, since it is an artery, the blood flow should go away from the probe (and not toward the transducer)? Thanks for your answer. Excellent video

[@frank4282]

Finally it got explained. Thank you.

[@JellyWaltzov]

Thanks for this outstanding explanation! I have a question: how do I know the direction of blood flow on transverse images? Where should my theoretical transducer be placed??

[@allahdadkhan3476]

Very nice description. I'm surprised why not adding more videos. Basic to advance Vascular ultrasound. There is no good KZbin channel about upper lower limbs carotid, obs Doppler, renal Doppler, abd Doppler and so on. No good channel. Ppl always search alot. Also plz change your channel name to the most common search word in ultrasound or vascular Doppler, Basic to Advance Vascular Color Doppler ultrasound or Vascular ultrasound madeeasy or anyother easy and easily search able. You are a great teacher.

Nice video.please how do you differentiate artery from vein using color Doppler

[@MrVeer58]

Excellent Lecture

[@obayal-raslan8403]

That was perfect Thank you for this explanation

[@hawkanhawks786]

This is great and very helpful. However, for the probe postition I personally find it easier to look at the color box or spectral dopplers line and angle. if it goes left to right, it sends the signal from left and if tilted right from left it sends the from the right. The probe is therefore on the side the signal is coming from.

[@halimrahman1210]

Beautiful voice!

[@thejulieperspective]

Please continue creating more videos. I will watch.

[@1995nicat]

[@sarkicinecmi3798]

Amazing!!! A tutorial about Carotid duplex would be very helpful...

[@cards0077]

INCREDIBLE! finally understand this. I thought probe was always on head side and thats why my flow direction was wrong many times. One question, when no color, is the line of site (dashed yellow line) perpendicular to the sample volume?

[@umeakukachinonso5786]

Thank you very much for this tutorial .

[@lynnroppolo2373]

Great video. The only part that confused me was when the head (orientation marker) was at the top left of screen but the probe was on the far right side of the vessel.

[@shcheat]

Please Do more Videos!

Extremely helpful. Much appreciated.

Hello , I was wondering if you know anything about PW doppler , if yes can I ask some questions?

[@botchedbeauty2346]

So, for bilateral upper extremity arterial exams. For BILATERAL brachial, radial, and ulnar arteries the indicator is UP TOWARDS THE PATIENT'S head for long axis images??

[@timy6301]

hi there i really appreciate for your video . could you make a video about colour doppler flow direction of steering box such as flow from left to right or right to left . i do not understand and confuse them . i do not know when it is right to left and when it is left to right . thanks

this is freaking great! thank you!

[@joyrobinson4324]

I'm confused because the color box is steered? When you put on color doppler, is it showing the correct flow of vessels? Is so, why do you invert the colors?

[@violeta6846]

I'm confused about the _ and + . CFA should be away and towards the body. But the probe is pointing backwards here?

[@MrVeer58]

Why not use the method of drawing the letter "H" for colour flow imaging too. Colour flow imaging - Can we also say the probe is placed on the side that is jutting out.

[@Mrs.Nations]

How do you know which way to steer the color box?

[@ilynpayne7491]

Where did you invert the image?

[@MrVeer58]

A picture showing the angle subtended by the probe/beam (with colour flow imaging) would further clarify the things.

[@jamieliu2746]

But why is the transducer on the left or right side of the screen? Shouldn’t it be on top?

So as far as what vein it is, is that something we can conclude from knowing the blood flow? I feel like I understand the mapping but I was confused on if it was a vein or artery.

How to determine direction if vessels are in transverse view?

[@rvtpro348]

You give the probe an angle, either towards or away from the patient's head, and use the color map relative to the direction you're angled. For example, if your probe is angled towards the patient's head, the transverse vessel is blue, and the color map shows blue on the top, you know that the flow is going towards your probe, or away from the patient's head!
