Trauma remains a significant cause of mortality and morbidity. Non-compressible torso haemorrhage is one of the key drives of these mortality data. Our contemporary management has focused on damage control resuscitation, with a focus on haemorrhage control, haemostatic resuscitation and permissive hypotension. The evidence for permissive hypotension lacks the robustness as other treatments, such as tranexamic acid. Despite this clinicians still target arbitrary systolic blood pressure cutoffs as both goals and ceilings of therapy. In this paper, we suggest that perhaps more consideration should be given to the diastolic blood pressure in bleeding trauma patients. The diastolic blood pressure is critical for coronary perfusion, and in turn the cardiac output responsible for cerebral blood flow. We suggest that a move to reframing resuscitation in terms of physiology may change the way that we resuscitate these patients and allow for more nuanced treatment strategies.
