Question

Enumerate different types of pumps used in cardiac surgery. Compare any two.

Hint:

In cardiac surgery, understanding the specific purpose of each type of pump is crucial for choosing the appropriate device based on the patient's condition.

Answer 1

Step 1: Types of pumps used in cardiac surgery.
There are different types of pumps used in cardiac surgery to support circulation during the procedure. The most common types include:

Heart-Lung Machine (Cardiopulmonary Bypass Machine)
Left Ventricular Assist Device (LVAD)
Right Ventricular Assist Device (RVAD)
Total Artificial Heart (TAH)

Step 2: Comparison of any two types of pumps.
Heart-Lung Machine: This pump is used to take over the function of the heart and lungs during open heart surgery. It pumps blood through the body and oxygenates it, allowing surgeons to work on a still heart.
Left Ventricular Assist Device (LVAD): LVAD is used to support the left ventricle of the heart, typically in patients with heart failure. Unlike the heart-lung machine, the LVAD works alongside the patient's heart and is often used for long-term support.
Step 3: Conclusion.
The heart-lung machine provides temporary support during surgery, while LVAD provides long-term support for heart failure patients.
