Which of the following types of information can you find along the BOTTOM of each screen on the AIC?
ELISA and Serotoin
HIT (heparin induce thrombocytopenia) should be verified by a positive______________ test and __________ release test?
Clinically significant hemolysis is plasma free hemoglobin greater than 40mg/dl x 2 in a 24 hour period.
Hemolysis
In the presence of adequate volume, and placement that appears in good position using a 2D echo, unresolved hemolysis requires that you continue to reposition the Impella. The rational being this is a 2D image and you cannot tell if the Impella is under Mitral apparatus.
Hemolysis
