i don't think this forum is the appropriate place to learn about how to insert IABPs. you really should be learning IABP placement under fluoro with supervision. the mechanics are pretty straight forward, but the devil is in the details, and rooted in good overall cath technique.
for example, with access. arterial access is typically single pass modified seldinger. double passing through the posterior wall can lead to retroperitoneal bleeding in a heparinized patient at a non-compressible site (if cephalad to the pelvic brim). any stick too far caudal, and you could cannulate the profunda femoris bifurcation leading to major vascular injury and possibly limb ischemia. the reason this is so important is because the IABP is typically >= 8French, which can do a lot of damage (our angiographies are performed with 6F introducers). the patient demographics for IABPs is also comorbid with vasculopathy. even in the cath lab with fluoro we are meticulous about access, which is one of the primary sources of complications. and that's just the beginning...
aside from the actual mechanics of IABP placement the real humdinger is nursing support. you're not going to get very far trying to place IABPs if the nurses are not experienced in setting it up and maintaining it (like in the cath lab, OR, CCU, or CT ICU). i'm sorry to say that i strongly think IABPs are better off being placed by the on-call cath team.
also, wouldn't you be a little incredulous about someone asking for technical advice about an invasive procedure on a public web forum?
