Perfusion Physiology/ Technology/ Clinical Perfusion
Test Your Knowledge in Clinical Perfusion
Welcome to the Clinical Perfusion Quiz! This interactive quiz is designed to assess your understanding of perfusion physiology, technology, and clinical practices related to myocardial protection and hemorrhagic management.
It consists of 10 carefully curated questions that cover various topics including:
- Myocardial protection techniques
- Hemolysis and its consequences
- Hemodilution effects
- Cannulation procedures
1) Myocardial protection is poor with a single venous cannula due to
A) inability to deliver retrograde cardioplegia
B) faster rewarming of heart
c) persistent LV distention
D) low perfusion pressures
E) poor venous drainage
2) Which of the following does not produce hemolysis?
a) excessive hemodilution
B) narrow tip arterial cannula
C) use of old banked blood in the prime
d) hypothermia
3) Hemolysis results in all of the following , EXCEPT,
A) hyperkalemia
B) vasoconstriction
C) hypernatremia
D) renal damage
4) Hemodilution does not results in
a) tissue edema
B) low perfusion pressure
C) spherocytosis of RBCs
D) microcytosis of RBCs
5) Direct left innominate vein cannulation is indicated in which of the following conditions?
A) supra cardiac TAPVC into vertical vein
B) TCPC operation
C) intra cardiac TAPVC
D) A-V canal repair
6) Pump flow for an infant < 3kg in weight ( in ml/kg/min at normothermia ) should be
A) 60- 80
b) 90-110
c) 120-140
d) 150- 200
7) In aortic cannulation, only a short length of the cannula is introduced into aorta so that
A) aortic dissection is avoided
B) arterial line resistance is less
C) cannula does not enter innominate artery
D) adequate pump flows can be delivered
8) The beveled tip of a straight aortic cannula should be directed towards
a) aortic valve
B) innominate artery
C) roof of the of transverse arch
d) descending aorta
E) lateral aortic wall
9) The direction of the tip of a short curved tip aortic cannula should be
A) towards aortic valve
B) towards ascending aorta
C) towards innominate artery
D) towards arch of the aorta
10) If after cannulation blood does not flow freely through an aortic cannula, then all of the following are possible, except,
A) tip is touching the wall of the aorta
B) tip has entered the innominate artery
C) tip is in the wall of aorta
D) tip is facing aortic root
