I would point out that hypotension is being used in two ways here. The first that you point out, SBP < 90 or MAP < 65 (also SBP drop by > 40 mm Hg) is to diagnose an organ dysfunction (cardiovascular). The second use of BP is as a target for resuscitation, and you are correct that MAP > 65 mm Hg is the target. There isn't really a disconnect; just two different reasons for looking at BP. Both definitions are valid. And what data we have on resuscitation targets pertains to achieving a MAP of 65 or greater.

It is a vasodilatory shock & if their systolic is 90 but diastolic is 30 they are not getting perfusion due to inadequate MAP. Hope this helps.

The Surviving Sepsis Campaign (SSC), defines hypotension as SBP < 90 or MAP < 65 (http://www.survivingsepsis.org/files/Tools/evaluationforseveresepsisscreeningtool.pdf) when screening a patient for severe sepsis. However, in the sepsis resuscitation bundle, one of the four standards to measure quality of fluid resuscitation is whether or not MAP is > 65. Interestingly, they do not specify that SBP be > 90, only MAP > 65. (http://www.survivingsepsis.org/About_the_Campaign/Documents/2008%20Guidelines%20Poster.pdf and http://www.survivingsepsis.org/Bundles/Individual_Changes/Pages/apply_vasopressors.aspx). In the context of SSC sepsis resuscitation, all hypotension (SBP < 90 or MAP < 65) does not seem to be equal. It appears that SSC uses MAP, not SBP, as the hemodynamic parameter to consider, when measuring the effectiveness of fluid and vasopressor resuscitation. How do providers on this list serve practice? Do you consider the patient with MAP < 65 as hypotensive, even it her/his SBP is > 90? Is there a risk of hypoperfusion of end organs, if MAP is still < 65 while SBP > 90?
