Clinical manifestation Hypotension Hypoperfusion Epinephrine
Clinical Manifestation • Hypotension • Hypoperfusion Epinephrine
Shock a acute, systemic pathological process in which EcbV decreased acutely leads to serious hypoperfuion in microcirculation and humoral factors change so that cell injury, metabolism disorder and organ dysfunction occur due to different seious disease and trauma
