IABP Exam Test Questions And Answers
Verified 100% Correct
What are the neurologic effects of IABP? - ANSWER increased blood flow to arch
vessels and brain
What is the renal effects to IABP? - ANSWER increased bloodflow to kidneys as long
as there is proper placement of balloon
A 1:1 IABP frequency means that the inflation occurs when? - ANSWER at every "R"
In 1:2 IABP frequency should assisted systole be lower than unassisted systole? -
ANSWER yes, assisted systole is lower than unassisted systole
Which should be lower unassisted end diastolic pressure or assisted end diastolic
pressure - ANSWER assisted end diastolic pressure is lower
Is late deflation or early inflation worse for a patient? Why? - ANSWER early inflation,
increases MVO2 demand,Aortic regurgitation, increased LVEDV, LVEDP, PCWP,
increased LV wall stress
What are the risks to early deflation? - ANSWER 1) retrograde coronary and carotid
blood flow
2) Increased risk of angina
3) sub-optimal diastolic augmentation
4) decreased afterload reduction
5) increased MVO2 demand
What is the consequence of early inflation? - ANSWER 1) balloon not deflating before
next systole
2) premature closure of Ao valve
3) potential increase in LVEDV, LVEDP, PCWP
4) increase in LV wall stress or afterload
5) Aortic regurgitation
6) increased MVO2 demand
What is the consequence of late inflation? - ANSWER 1) less volume to assist
2) sub-optimal diastolic augmentation
3) sub-optimal coronary artery perfusion
, What are the consequences of late deflation? - ANSWER 1) increased afterload
2) increased MVO2 demand because heart must work harder than w/o IABP
3) increased SVR
What are the indications for use of IABP? - ANSWER 1) refractory angina
2) impending infarction
3) acute MI
4) refractory ventricular failure
5) complication of acute MI
6) cardiogenic shock
7) support for interventional procedures
8) ischemia from intractable ventricular arrhythmias
9) septic shock
10) weaning from bypass
11) low cardiac output syndrome
12) mechanical bridge to VAD
What are the contraindications to IABP? - ANSWER 1) severe AI
2) abdominal or aortic aneurysm
3) severe calcifide aorta-iliac disease or peripheral vascular disease
4) sheathless insertion w/ severe obesity, scarring groin
What is the primary trigger to use for IABP? - ANSWER ECG "R" wave
During cardiac arrest what should you use as trigger for IABP? - ANSWER pressure
upstroke of 10-15 mm cause deflation
Every trigger signals to do what? - ANSWER deflate balloon
If the heart rate is greater than 120 BPM you should use what ratio? If HR< 120 BPM
what ratio? - ANSWER 1:2
1:1.12
What are the primaryeffects of IABP on MVO2 supply and demand? - ANSWER IABP
inflation increases MVO2 supply, increase coronary BF
IABP deflation decreases MVO2 demand, decreases afterload
What are the 3 major influences that lead to LV failure and an increase in MVO2
demand? - ANSWER 1) vasoconstriction
2) hypervolemia
3) tissue hypoxia
Volume and pressure inside the left ventricle at the end of diastole is referres to as? -
