In reporting systemic vascular resistance measurements, one can use mmHg/min/L, dyn/sec/cm5, or pascals per second/cm2. Is there a general consensus from the field of applied physiology or medical physiology as to which one to use? There seems to be a varied use of SVR units used amongst different publications. Any suggestions would be greatly appreciated.
Thank you
You can consult the CV textbook by Richard Klabunde, who also posts an electronic version of his book. The book is well written and I use it often as background reading for CV physiology and pathophysiology/pharmacology. The url to your specific question is:

Thank you for the recommendation Carolyn. I have read some of that book before, but I will be sure to read this chapter in particular.
I would have to say specifically in the US (and I deal more emergency medicine and prehospital clinicians) we utilize the dyn/sec/cm^5 when we discuss patients or case studies. This is mainly due because that is what people were taught, so that is what they use. All of the units you mentioned are usable and appropriate -- but it would be best to tailor the units to what type of audience you discussing with.
Thank you Eric. I prefer the mmHg/min/ml unit, as I can understand these values better coming from a medical perspective where mmHg is a pretty standard unit measurement. I have seen in multiple medical/physiology papers no standard usage of a single unit. It looks like one can report them as they wish.
