Abstract
Abdominal counterpulsation improves blood flow during other-wise standard CPR in animal
models and in electronic models of the circulation. The method generates both central
aortic and central venous pressure pulses. Success depends upon maximizing the former
and minimizing the latter. Solution of a simple, first-order, differential equation
may provide insight into proper technique. The equation suggests that the central
arteriovenous pressure difference is maximized when pressure is applied directly over
the abdominal aorta and when fluid loading is avoided. Proper technique may be critical
in generating the largest possible arteriovenous pressure difference.
