Main Question or Discussion Point

Have been referring to this forum a lot and I think I finally understand it. However I couldn't find a discussion specific to applying the Laws of Ohm, Poiseuille and Bernoulli's to why we use a pressure wire to study coronary blood flow through a lesion site in the coronary artery. So I made some assumptions on what I think is correct and of course assumptions is a terrible thing to do.

So I wrote it all down. It is 6 pages long. I really, really need someone to read it and help me correct my mistakes. I work in a Hospital and am a Clinical Cardiac Physiologist.

I realize 6 pages is a lot to ask someone to read. It is not homework or an assignment that I am doing. It is personal reflection. I use the equipment. I understand what the numbers mean and how to interpret it to the patient on the table but I don't understand the physics behind it. So I thought it was time I did.

My plan is to finish my write up about the physics side then present it to my other colleagues in the Hospital.

It is written on google docs. I tried to think of a way to condense it so I can add to this forum for discussion but it isn't straight forward when you add all the laws in. The complete picture needed 6 pages to let the words flow as naturally as possible.

So kinda stumped as how to get help. Should I just pasted the whole 6 pages here or do them in chunks or do something else? Anyone's thoughts on what to do would be welcome?

Welcome to the PF.

I will send you a message with my e-mail address, and you can send me a PDF copy to look over. From that we can figure out the best way to proceed. At the very least, we should be able to discuss portions of your paper, especially any sections where you have questions. Is there a bibliography listing the information sources that you used in writing up the paper?

Bibliography? Yes and no. My main reference is 'PhysicsForum'! Been reading everything I could from here. All bits and pieces that I tried to add together to gain the overall picture.

Well, for a proper paper (and especially one you want to present), you should find applicable references and annotate any technical statements you are making in the paper. Even the articles that I read in JEMS or EMS World have references for authoritative statements that are made in the articles...

Apologies to all for the delay. The OP and I are working on gathering valid references for his paper, and we will try to post focused questions in a new thread soon. This thread here is closed for now.
