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.

Dense mosaic pattern of turbulence appears above the aortic valve near the outlet area of the catheter

Describe what correct impella catheter position look like when color Doppler is added to echo?

1. Turn AIC on Hold For 3 Sec or till light alluminates 2. Press MENU and select CASE START and Press Select knob 3. Open Cassette Door by pressing the left release bottom. 4. Spike D5W bag, and insert cassette and slide purge pressure transmitter and close door 5.
