  1. What is mean arterial pressure (MAP) and what is the target during bypass?

    Answer: The average arterial pressure during a cardiac cycle, typically maintained at 50-80 mmHg during bypass

    MAP represents the average pressure driving blood through organs. During bypass, it is typically maintained between 50-80 mmHg to ensure adequate organ perfusion.

  2. What does mixed venous oxygen saturation (SvO2) indicate during bypass?

    Answer: The balance between oxygen delivery and consumption

    SvO2 reflects the balance between oxygen delivery and tissue consumption. Low values indicate inadequate perfusion or increased oxygen demand.

  3. What is the normal range for blood gas pH during cardiopulmonary bypass?

    Answer: 7.35 to 7.45

    Maintaining pH in the normal range of 7.35-7.45 during bypass is essential for proper enzyme function and cellular metabolism.

  4. What does a rising lactate level during bypass indicate?

    Answer: Inadequate tissue perfusion or oxygen delivery

    Rising lactate indicates that tissues are not receiving adequate oxygen and are relying on anaerobic metabolism, suggesting inadequate perfusion.

  5. What is the purpose of monitoring hematocrit during bypass?

    Answer: To assess blood dilution and oxygen-carrying capacity

    Hematocrit reflects the proportion of red blood cells in the blood, indicating oxygen-carrying capacity. Excessive hemodilution may require blood transfusion.

  6. What is venous reservoir volume and why is it monitored?

    Answer: The volume of blood in the venous reservoir that serves as a safety buffer preventing air embolism

    The venous reservoir holds blood returned from the patient and provides a safety buffer. Low levels risk introducing air into the circuit.
