Permissive Hypotensionis also known as hypotensive resuscitation or low volume resuscitation

What is it?

A resuscitation strategy in the critically ill trauma patient (primarily applicable to penetrating trauma but also adapted to blunt trauma) where we allow the systolic BP to remain as low as necessary to avoid exsanguination while still maintaining critical end organ perfusion. (typically defined as appropriate mental status & or the presence of a radial pulse)

The Thought Process:"Don't pop the clot"...

By allowing lower blood pressures we avoid the potential disruption of an unstable fresh clot and thus worsening bleeding caused by higher BP's.
