IABP Therapy answers
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✔✔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✔✔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✔✔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✔✔Deflation
What term is described by the following?
-Normal peak systolic pressure✔✔First hump
What term is described by the following?
-Correlates with aortic valve closure
-Should be "V" shaped✔✔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✔✔Second
hump
What term is described by the following?
-Relates to balloon deflation just before the next systole
-Should be "U" shaped✔✔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✔✔Trigger
What term is described by the following?
-Inflation and deflation times in reference to the cardiac cycle✔✔Timing
What does IABP use to increase aortic pressure during diastole while decreasing
aortic pressure during ejection?✔✔Counter pulsation
What is controlled by the following factors?
-Coronary anatomy
-Diastolic pressure
-Diastolic time
-Oxygen extraction✔✔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✔✔Myocardial oxygen demand
The following are measurements of what?
-CO
-HR
-SV✔✔Cardiac performance
What are the following determining factors for?
-Preload
-Afterload
-Contractility
-HR✔✔Stroke volume
What are the primary hemodynamic effects of IABP?✔✔Increased supply
Decreased demand
The following are all what kind of hemodynamic effects of IABP?
-Increased cardiac output
(CO)/ cardiac index (CI)
‒ Decreased heart rate
‒ Decreased pulmonary capillary wedge pressure (PCWP)/ peripheral arterial
disease (PAD)
-Decreased systemic vascular resistance (SVR)
-Decreased systolic pressure
-Decreased end diastolic pressure
-Increased mean arterial pressure (MAP)✔✔Secondary effects
What are the IABP balloon size based on?✔✔Patient height
