Think:
Is MCS choice appropriate for clinical scenario?
Understand and frequently monitor connections & hemodynamics
Understand potential complications

Intra-aortic balloon pump
Diastolic augmentation, MAP during augmented beat
afterload and end-diastolic pressure
CO augmentation 0.7-1.4 l/min
Position: IABP tip at carina level on CXR

Adjust FiO2: oxygenation
Adjust sweep speed: ventilation
Watershed area: Where blood pumped by native mixes with ECMO blood - matters where ABG is drawn from
afterload - must ensure LV vented and AV opening to avoid catastrophe!
