Cardiogenic Shock

Cardiogenic shock is a severe condition characterized by the heart's inability to pump blood effectively, often resulting from myocardial infarction. This leads to signs of peripheral hypoperfusion, including cyanosis, pallor, diaphoresis, weak peripheral pulse, cool and clammy skin, and delayed capillary refill.

Signs of peripheral hypoperfusion
-cyanosis -pallor -diaphoresis -weak peripheral pulse -cool & clammy skin -delayed cap refill
-tachypneic -crackles -⇧ PAWP -⇧ SVV -⇧Pulmonary vascular resistance
⇧SVR-->⇧ O2 consumption
-tachycardia -hypotension -narrowed pulse pressure
