PLACEMENT SIGNAL WAVEFORM
The placement signal waveform displays a pressure measurement from the differential pressure
sensor. The scale for the placement signal waveform is displayed to the left of the waveform. The
default scaling is -20 to 60 mmHg. The scale can be adjusted in increments of 10 mmHg for a
maximum range of -60 to 340 mmHg or a minimum range of 0 to 40 mmHg.
To the right of the waveform is a display that labels the waveform, provides the units of
measurement, and shows the maximum and minimum values and the average value from the
samples received. At the bottom of that window is the time scale, which you can set by pressing the
DISPLAY soft button.
See AIC package insert for more i nformation.
SUCTION
If suction is an issue, the flow displayed on the controller may be higher than the actual Impella RP
flow rate. If the suction alarm appears on the controller when the Impella RP
between P-7 and P-9, decrease P-level to P-6, or to P-5 or P-4, as needed, to resolve suction. If the
suction alarm continues when the P-level is between P-4 and P-6, momentarily stop the Impella RP
to resolve the suction issue and then restart it immediately.
USE OF THE REPOSITIONING SHEATH AND INTRODUCER
1. Flush the sidearm of the repositioning sheath located on the catheter shaft.
2. Attach a stopcock and flush the repositioning sheath prior to advancing the sheath.
3. Apply manual pressure above the puncture site and remove the 23 Fr peel-away introducer
completely from the vein over the catheter shaft.
4. Grasp the two wings and bend back until the valve assembly comes apart. To do this,
first stretch then snap the flexible valve mechanism that temporarily holds the two wings
together. Continue to peel the two wings until the introducer is completely separated from
the catheter shaft. (Note: Do NOT peel the 23 Fr peel-away introducer over the tip of the
repositioning sheath.)
5. Place two dead-end caps on the repositioning sheath stopcock to prevent further usage.
The sideport should not be used to give medication or draw blood because the blood could
potentially clot. Pressure bags should not be connected to the sideport of the repositioning
sheath. If a pressure bag is connected, the sideport must have an infusion pump or flow
limiting valve in place to control the amount of fluid administered to the patient.
6. Slide the repositioning sheath over the catheter shaft and advance it into the femoral vein
to the yellow eyelet.
7. Make sure there is no bleeding at the transition from the repositioning sheath to the
femoral vein. Close and dress the wound.
