CVP Cardiopulmonary Bypass 2

Question 1

What is the typical blood flow rate during adult cardiopulmonary bypass?

Accepted Answer

2.2 to 2.4 L/min/m² of body surface area

Answer

The standard perfusion flow rate of 2.2-2.4 L/min/m² maintains adequate organ perfusion during bypass.

Question 2

What is myocardial protection during cardiac surgery?

Accepted Answer

Techniques to prevent heart muscle damage during the period the heart is stopped

Answer

Myocardial protection involves strategies such as cardioplegia to prevent ischemic damage to the heart while it is arrested during surgery.

Question 3

What is cardioplegia?

Accepted Answer

A solution delivered to the heart to arrest it and protect the myocardium during surgery

Answer

Cardioplegia is a cold, potassium-rich solution delivered to the heart that causes it to stop beating and reduces metabolic demand, protecting it during surgery.

Question 4

What is the purpose of an arterial filter in the bypass circuit?

Accepted Answer

To remove microemboli, air bubbles, and debris from blood before it returns to the patient

Answer

The arterial filter is a critical safety device that removes air bubbles, particulate matter, and microemboli before blood is returned to the patient.

Question 5

What is ultrafiltration during cardiopulmonary bypass?

Accepted Answer

A technique to remove excess fluid and concentrate blood components

Answer

Ultrafiltration uses a hemoconcentrator to remove excess water and low-molecular-weight substances from the blood, reversing hemodilution.
