|
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
|
|
Term
| If effective IABP therapy is being achieved, the diastolic augmentation peak pressure should be higher than or equal to the: |
|
Definition
|
|
Term
| IABP is called counterpulsation because the balloon inflates during _______ and deflates during _______. |
|
Definition
|
|
Term
| A fully inflated counterpulsation balloon rarely occupies more than _______ of the total diameter of the aorta. |
|
Definition
|
|
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
|
|
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
|
|
Term
| During transport, the patient's distal pulses below an IABP insertion site should be assessed every _______ minutes. |
|
Definition
|
|
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
|
|
Term
| Utilizing ECG triggers, the IABP machine will deflate the balloon on the _______ wave. |
|
Definition
|
|
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
|
|
Term
| The relationship between _______ and contractility is described in the Frank-Starling curve. |
|
Definition
|
|
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
|
|
Term
| Pressure is the preferred IABP trigger during: |
|
Definition
| cardiopulmonary resuscitation (CPR). |
