Clinical manifestation Hypotension arrowed pulse pressure Cold and clammy skin olis gurla Dulled sensorium

Clinical Manifestation • Hypotension • Narrowed pulse pressure • Cold and clammy skin • Oliguria • Dulled sensorium

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

Shock Microcirculation disorder t cellular injury t Humoral factors (inflammatory mediators)

Shock Microcirculation disorder + Cellular injury + Humoral factors (inflammatory mediators)
