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.
