A.
Consider VA ECMO-related causes of cardiac arrest:
  • Severe LV overload
  • LV and/or aortic root thrombosis due to blood stasis
  • Decreased myocardial oxygen delivery (DO2) due to differential oxygenation
  • Lack of preload due to excessive venous drainage
B.
Consider other reversible causes of intrahospital cardiac arrest:
  • Electrolytes abnormalities
  • Metabolic disturbances
  • Medications-related arrhythmia
  • Cardiac tamponade
  • Tension pneumothorax
  • Acute myocardial infarction
  • Pulmonary embolism
  • Not bleeding-related hypovolemia
C.
Treat the immediately reversible potential cause(s) if or as detected. Plan emergent treatment of the potential causes requiring cath lab or surgery if/as detected.
