Impella 2.5/CP Quiz What is the most appropriate step to take if the placement signal is aortic and the AIC is displaying an “Impella Position Wrong” alarm? a. Rapidly infuse volume b. Increase the motor speed of the Impella c. Drop to P-2, contact the physician and order an echo d. Begin CPR Which of the following could be a sign of suction? a. Lower than expected flow b. Reduced mean motor current c. Reduction in patient’s blood pressure d. All of the above When caring for a patient with an Impella 2.5 or Impella CP device: a. Raise the head of the bed to higher than a 30-degree angle b . Monitor pedal pulses and the insertion site c. Increase to the maximum possible Impella flow rate before initiating CPR d. All of the above Which component is added to the system configuration when transferring from the initial set-up to the standard configuration of the Impella 2.5 or Impella CP system? a. Purge cassette b . Sodium chloride bag c. Dextrose solution d. All of the above The __________ provides blood pressure values to the red Impella plug to generate the placement signal. a. Open pressure port b. Inlet area c. Pigtail d. Purge cassette What does the placement screen show when the Impella 2.5 or Impella CP device is correctly positioned across the aortic valve? a. Aortic placement signal and flat motor current b. Aortic placement signal and pulsatile motor current c. Ventricular placement signal and flat motor current d. Ventricular placement signal and pulsatile motor current If low CVP precipitates a suction alarm rapid infusion of volume can remedy the situation after dropping the P-level. a. True b. False Which of the following is the location of the purge disc, from which the AIC reads purge pressure and automatically adjusts purge flow to keep purge pressure within the specified range? a. A b. B c. C d. D

The Automated Impella Controller screen shown here is called the: a. Startup screen b. Placement screen c. Home screen d. Infusion screen The function of the Automated Impella Controller is to: a. Provide an interface for monitoring and controlling the Impella devices b. Provide purge fluid to the Impella device c. Provide backup power when the Impella system is not on AC power d . All of the above A low purge pressure alarm, caused by a purge pressure less than 300 mmHg and a purge flow rate of 30 mL/hr may be due to: a. A loose connection at the yellow luer lock b. A leak in the purge cassette c. Dextrose concentration too low d . Any of the above Which letters correspond with the correct device components as shown in the illustration? A - Inlet, B - Outlet, C - Pigtail A - Pigtail, B - Inlet, C - Outlet A - Outlet, B - Pigtail, C - Inlet Clinicians should use a _____________ echo to view the position of the Impella device in the left ventricle: a. Parasternal long axis (TTE) b. Short axis transesophageal (TEE) c. 4-Axis view d. Subcostal Blood flow through the Impella 2.5 or Impella CP device will __________ left ventricular end-diastolic volume and pressure and __________ the mean aortic pressure and flow. a. Increase; increase b. Increase; decrease c. Decrease; increase d. Decrease; decrease
