  1. Centrifugal blood pumps generate flow by:

    Answer: Creating a rotating magnetic field that spins an impeller or cone

    Centrifugal pumps use a rotating impeller or cone driven magnetically to impart kinetic energy to blood, generating non-occlusive constrained vortex flow.

  2. A key safety advantage of centrifugal pumps over roller pumps during CPB is:

    Answer: They cannot generate excessive negative or positive pressures that could cause tubing rupture or cavitation

    Centrifugal pumps are non-occlusive and will stall rather than generate dangerously high pressures or extreme negative pressures that could rupture tubing or cause cavitation.

  3. Antegrade warm blood cardioplegia is delivered via the:

    Answer: Aortic root or direct coronary ostia

    Antegrade cardioplegia is delivered through the aortic root or directly into coronary ostia, following the normal direction of coronary blood flow.

  4. Modified ultrafiltration (MUF) performed after CPB primarily serves to:

    Answer: Hemoconcentrate the patient and reduce the systemic inflammatory response

    MUF removes excess fluid and inflammatory mediators accumulated during bypass, improving hematocrit and attenuating the systemic inflammatory response post-CPB.

  5. During retrograde cardioplegia delivery, the cannula is placed in the:

    Answer: Coronary sinus

    Retrograde cardioplegia is delivered via a balloon-tipped catheter placed in the coronary sinus, allowing the solution to flow against the normal direction of coronary venous drainage.

  6. The sweep gas flow rate through the oxygenator primarily controls:

    Answer: Carbon dioxide removal and PaCO2 levels

    Increasing sweep gas flow enhances CO2 removal (ventilation effect), while oxygen content of the sweep gas determines oxygen transfer to blood.

  7. Which alarm would MOST urgently require the perfusionist to immediately cease CPB pump flow?

    Answer: Arterial line pressure high alarm with visible tubing distension distal to the pump

    A high arterial pressure alarm with distal tubing distension indicates potential aortic cannula obstruction or massive resistance, requiring immediate cessation of flow to prevent circuit rupture or aortic injury.
