Question:

I am curious to know why some of our medical directives are systolic driven rather than mean arterial pressure driven? 
 
Current research suggests MAP is more accurate than SBP in non-invasive monitoring and better reflects perfusion pressure in shock, is a better indicator of organ perfusion and is a better predictor of post-cardiac arrest outcomes. 
 
Even ACLS recommends a target MAP of 65mmHg for post-cardiac arrest care as opposed to a certain SBP.  
 
Is this a change that OBHG would consider in future iterations of the medical directives? 

Answer:

This question is timely. The use of MAP within medical directives is currently being reviewed as part of the Comprehensive Medical Directive Review.
