POSITIONING AND STARTING THE IMPELLA
®
RP
CATHETER
Retrograde flow will occur from the pulmonary artery back into the inferior vena
cava if the Impella
®
RP Catheter is set at performance level P0.
When the Impella
®
RP is properly positioned across the pulmonary valve, but is not yet
running, the placement signal will be similar to a pulmonary arterial waveform. After starting
the Impella
®
RP, the amplitude of the placement signal will increase by a factor of 2 to 2.5,
depending on the selected performance level.
1.
Press the
FLOW CONTROL
soft button to open the menu.
2.
Turn the selector knob to increase the performance level icon.
3.
Press the selector knob to select the new performance level.
4.
The catheter operation icon in the lower left corner of the screen begins rotating when
the Impella
®
RP Catheter begins to operate.
5.
Increase performance level to P9 to confirm correct and stable placement. Evaluate the
catheter position and remove any excess slack. The catheter inlet area should be in the
inferior vena cava and the outlet area in the pulmonary artery. Verify placement with
fluoroscopy.
