Why the study?
Does intra-aortic balloon counterpulsation with 32 cc versus 40 cc inflation volume affect cardiac output in patients requiring IABP?
Does intra-aortic balloon counterpulsation with 32 cc versus 40 cc inflation volume affect cardiac output in patients requiring IABP?
Smaller IAB inflation volumes (32 cc) provide similar hemodynamic improvement to larger volumes (40 cc) overall, though larger volumes may further augment cardiac output in patients with smaller body surface area.
No takes yet. Share an insight, caveat, or question.
Supports similar CO with 32 cc vs 40 cc IABP overall; leaves open optimal volume in small-BSA patients.
Cohen et al. (2002) studied this question.
