Occult Causes of Non-Response to Vasopressors

vital disclaimer: the cognitive response to hypotension should not be reaching for a vasopressor. the primary therapy for hypotension is treatment of the underlying pathology 

definition: patients who despite substantial vasopressor doses do not show HD parameter improvements. failure of response -> cognitive pause + consideration of reasons 

considerations for non-responders:

 - acidosis 
 - hypothyroid 
 - anaphylaxis 
 - adrenal insufficiency 
 - hypoCa2+ 
 - occult bleeding 
 - toxicologic 
 - 2nd cause shock
