Term
The intra-aortic balloon pump (IABP) catheter offers a mechanical means of balancing _______ and _______.
Definition
myocardial oxygen supply; oxygen demand
Term
During transport of a patient undergoing IABP counterpulsation therapy, the CCTP notes a small amount of blood in the gas lumen of the catheter. The CCTP knows that:
Definition
this is a sign of a balloon leak, and counterpulsation should be stopped.
Term
Helium is used to inflate the IABP balloon because:
Definition
its low molecular weight allows it to be pumped faster.
Term
What are contraindications to IABP therapy
Definition
iliac arterial disease.

abdominal or aortic aneurysm.

severe aortic valvular insufficiency.
Term
An injury to the myocardium resulting in a decrease in stroke volume would require an increase in _______ to maintain cardiac output.
Definition
heart rate
Term
If effective IABP therapy is being achieved, the diastolic augmentation peak pressure should be higher than or equal to the:
Definition
systolic pressures.
Term
IABP is called counterpulsation because the balloon inflates during _______ and deflates during _______.
Definition
diastole; systole
Term
A fully inflated counterpulsation balloon rarely occupies more than _______ of the total diameter of the aorta.
Definition
1/2
Term
When observing the ECMO pressure waveform, the CCTP will see:
Definition
no waveform, because ECMO is nonpulsatile.
Term
The mitral and tricuspid valves open during what phase of the cardiac cycle?
Definition
ventricular filling
Term
Counterpulsation is most frequently utilized to assist patients suffering from:
Definition
left ventricular failure.
Term
The cardiac cycle is made up of
Definition
atrial systole.

isovolumetric relaxation.

ventricular filling.
Term
When an IABP balloon is active, the highest waveform on the pressure monitor is called the:
Definition
diastolic augmented.
Term
During transport, the patient's distal pulses below an IABP insertion site should be assessed every _______ minutes.
Definition
15
Term
The counterpulsation balloon deflates at the end of _______ just prior to _______.
Definition
diastole; ventricular ejection
Term
You are working with a CCT team that transports approximately six IABP patients annually. On arrival at a referring facility to transfer a patient with active counterpulsation therapy in place, which of the following crew additions would be best for patient care?
Definition
the addition of a perfusionist to the team
Term
The CCTP is transporting a patient who has recently had an IABP removed. The patient begins to complain of leg numbness and tingling, as well as increasing pain. Assessment reveals a pale, swollen limb with absent distal pulses. The CCTP suspects:
Definition
limb ischemia caused by compartment syndrome.
Term
The dicrotic notch on an arterial pressure waveform is caused by the:
Definition
arterial valve closing.
Term
Utilizing ECG triggers, the IABP machine will deflate the balloon on the _______ wave.
Definition
R
Term
The ostea to the coronary arteries are located:
Definition
at the base of the aorta.
Term
To prevent over or under inflation during atmospheric pressure changes in air transport, the IABP balloon pressure should be set to _______ mode.
Definition
autofill
Term
The relationship between _______ and contractility is described in the Frank-Starling curve.
Definition
preload
Term
During CPR on a patient with active counterpulsation therapy, the CCTP should:
Definition
turn the IABP to pressure-sensing mode.
Term
The assist ratio allowing for the best evaluation of the IABP waveform is:
Definition
1:2.
Term
Pressure is the preferred IABP trigger during:
Definition
cardiopulmonary resuscitation (CPR).
