Question 1.

Assess the timing on the following strip.

a. Correct timing
b. Early inflation and late deflation
c. Early inflation and early deflation
d. Correct inflation and early deflation
e. Late inflation and early deflation

Question 2.

A. Assess the timing on the following strip.

a. Late inflation and early deflation
b. Correct inflation and early deflation
c. Early inflation and late deflation
d. Late inflation and late deflation
e. Early inflation and early deflation

B. Which trigger do you think is selected?

a. Pattern
b. Peak
c. V Pace
d. Internal
e. Arterial Pressure

Question 3.

What is wrong with the arterial pressure line on the following strip?

a. AP line is dampened and needs to be flushed.
b. Transducer needs to be zero'd.
c. The IAB is too high and the tip of the arterial line is being occluded as it hits up against the aortic arch.
d. Nothing.
e. There is air in the pressure tubing.

Question 4.

A. Assess the timing on the following strip.

a. Early inflation and early deflation
b. Late inflation and late deflation
c. Correct inflation and late deflation
d. Late inflation and early deflation
e. Correct timing

B. The pump is in Peak trigger mode. What part of the ECG complex is being recognized as the trigger event?


a. The R wave
b. The pacer spike
c. The arterial pressure waveform
d. The T wave
e. No trigger is seen

Question 5.

Assess the timing on the following strip

a. Late inflation and correct deflation
b. Early inflation and correct deflation
c. Early inflation and early deflation
d. Correct inflation and late deflation
e. Late inflation and early deflation

Question 6.

Is this a timing or a triggering problem?

a. Timing problem
b. Trigger problem

Question 7.

The following strip was recorded from a patient post CABG. He had atrial and ventricular temporary pacing wires inserted during surgery.

A. What is wrong with the pacemaker?

a. The connections to the atrial and ventricular wires are reversed so that the ventricles are being paced first then the atria.
b. The pacemaker is functioning correctly.
c. The pacer is not sensing appropriately.
d. The pacer is not capturing.
e. The patient is not paced at this time.

B. Would V Pace be an appropriate trigger choice at this time?

a. Yes.
b. No. The second pacer spike (the potential trigger event) is after the QRS complex so timing could be an issue.

Question 8.

The following patient is in Cardiogenic Shock. A 40cc IAB was inserted yesterday. It is in the correct position per CXR. He is 6'4" and 131.5kg. His HR is 146, CI is 1.3, PCWP is 28 and SVR is 433. He is on Dobutrex at 20mcg/kg/min, Primacor at 20mcg/kg/min, Dopamine at 15mcg/kg/min, Levophed at 101mcg/kg/min and Heparin at 1000u/hr.

Why is his PDP less than his PSP?

a. There is a timing error.
b. He is dry and needs more volume.
c. His cardiac status is so poor that an IABP cannot provide adequate support and a VAD should be considered.
d. The IABP is mal functioning.
e. It is snowing outside.

Question 9.

When the pump is in a 1:2 assist ratio there are no alarms. As soon as the pump is placed in a 1:1 assist it alarm POSSIBLE HELIUM LOSS. What is the problem?

a. There is a leak in the balloon.
b. The cold trap bottle is full.
c. There is a loose connection in the gas tubing.
d. There is a partial obstruction of the gas flow as evidenced by the wide deflation artifact.
e. There is a leak in the pump.

Question 10.

Assess the timing on the following strip.

a. Correct timing
b. Late inflation and correct deflation
c. Early inflation and late deflation
d. Late inflation and early deflation
e. Correct inflation and early deflation
