IABP Therapy EXAM with completesolutions 2024/2025
What term is described by the following?
-Mechanical cardiac assist device that benefits patients with actual or potential
life-threatening circulatory problems
-Provides hemodynamic support to patients - ANSWER-Intra-aortic balloon pump
(IABP)
What term is described by the following?
-Circulatory support provided by a balloon inserted into the thoracic aorta,
inflated during diastole and deflated during systole
-Reduces the resistance to left ventricular ejection and increases coronary and
systemic blood flow - ANSWER-Intra-aortic balloon counter pulsation (IABC)
What term is described by the following?
-Takes place at the onset of diastole, balloon inflation increases (at dicrotic
notch) aortic diastolic pressure to a level higher than systolic pressure
-Displaces a volume of blood equal to its inflation volume - ANSWER-Inflation
What term is described by the following?
-Occurs at the end of isovolumetric contraction just before opening of the aortic
valve (anacrotic notch)
-Occurs just before systole reduces afterload
-Maintained until the onset of diastole - ANSWER-Deflation
What term is described by the following?
-Normal peak systolic pressure - ANSWER-First hump
What term is described by the following?
-Correlates with aortic valve closure
, -Should be "V" shaped - ANSWER-First dip
What term is described by the following?
-Termed diastolic augmentation or peak diastolic pressure (PDP)
-Produced by balloon inflation up aortic valve closure at the dicrotic notch
-Ideally raises diastolic pressure to a level higher than the systolic pressure
-Mechanically increases optimizing coronary and systemic blood flow - ANSWER-
Second hump
What term is described by the following?
-Relates to balloon deflation just before the next systole
-Should be "U" shaped - ANSWER-Second dip
What term is described by the following?
-Physiologic signal from the patient to the computer within the IABP console
-Used to indicate the beginning of cardiac cycles and length of R-R intervals
using ECG
-The pneumatic system within the console then appropriately deflates and
inflates the balloon in sync with the patient's cardiac cycles - ANSWER-Trigger
What term is described by the following?
-Inflation and deflation times in reference to the cardiac cycle - ANSWER-Timing
What does IABP use to increase aortic pressure during diastole while decreasing
aortic pressure during ejection? - ANSWER-Counter pulsation
What is controlled by the following factors?
-Coronary anatomy
-Diastolic pressure
-Diastolic time
-Oxygen extraction - ANSWER-Myocardial oxygen supply
What is affected by the following factors?
-Increased HR increases demand
-Increased afterload increases demand
-Increased preload increases wall tension
-Increased contractility increases demand - ANSWER-Myocardial oxygen demand
The following are measurements of what?
-CO
-HR
