P-2

Question 12

Which display setting should be utilized during transport?

Answer 12

Placement setting to watch waveforms for proper placement

Question 13

What kind of waveform should be present with the motor current, regardless of Impella type?

Answer 13

pulsatile waveform

Question 14

Where are the inlet and outlet areas of the Impella RP?

Answer 14

Inlet in the IVC and outlet in the PA. Bypasses the right ventricle

Question 15

What do you do when you receive a pump position wrong alarm?

Answer 15

You drop to P-2 level, begin supporting the patient medically, and alert the receiving

Question 16

Are there position alarms for both left and right sided Impellas?

Answer 16

No. There are no position alarms for the Impella RP

Question 17

What are the 3 main reasons for a suction alarm?

Answer 17

Low volume in left ventricle.
Incorrect pump position.
Right heart failure.

Question 18

What do you do with a suction alarm?

Answer 18

Drop the P level by 1-2, reassess fluid status. Drop P level by 1-2 each time until suction alarm goes away. Do no go below P-2. If unable to resolve, notify receiving.

Question 19

How do you troubleshoot a Purge Pressure high alarm?

Answer 19

Check purge fluid tubing for kinks. If not resolved, contact receiving.

Question 20

How do you troubleshoot a Purge Pressure low alarm?

Answer 20

Check purge fluid tubing for leaks or loose connections. If not resolved, contact receiving.

Question 21

How do you troubleshoot an Air in Purge Line Alarm?

Answer 21

Click the Purge Menu button and then De-Air Purge System. Follow the prompts.

Question 22

Which pressure measurement do you use for patient care decisions and status?

Answer 22

MAP

Question 23

Which P setting do you utilize during CPR?

Answer 23

P-2

Question 24

What waveform needs to be assessed after achieving ROSC?

Answer 24

Motor current needs to be pulsatile. If not pulsatile, keep P level at P-2 and notify receiving. If it is pulsatile, increase P level to the previous level.

Question 25

Which P level is required for defibrillation?

Answer 25

No requirement. Defibrillate at any time at any level.

Question 26

Where should the head of bed be during transport?

Answer 26

No greater than 30 degrees.

Question 27

What are you assessing for at the insertion site?

Answer 27

Hematoma and bleeding.

Question 28

Should the Impella be flat against the skin at insertion site?

Answer 28

No. It should be ramped up at the angle of insertion. Flat against skin can cause bleeding.

Question 29

Why are inotropes sometimes utilized with Impellas?

Answer 29

Impellas are preload dependent. The inotrope helps move fluid from the right side to the left side where the Impella sits.

Question 30

Impellas are preload ______ and afterload ______.

Answer 30

preload dependent and afterload sensitive

Question 31

What is the phone number for 24/7 Impella help?

Answer 31

1-800-422-8666
