Question

Intrapulmonary shunting is defined as:

A) the return of unoxygenated blood to the left side of the heart.
B) a decrease in the surface area of the alveoli caused by damage.
C) a condition in which too much carbon dioxide is eliminated.
D) failure of blood to bypass an obstruction in a pulmonary artery.

Answer 1

Intrapulmonary shunting is a condition in which the ventilation of the lungs decreases without affecting perfusion. It can result from infection or edema in the lung, leading to a decrease in gas exchange and a change in the V/Q ratio.

Step-by-step explanation:

Intrapulmonary shunting refers to a physiological condition where there is a decrease in the ventilation of the lungs without affecting perfusion. This can occur due to infection or edema in the lung, obstructing certain areas and leading to a decrease in gas exchange. It results in a change in the V/Q ratio, reducing the amount of oxygen in the blood and increasing the amount of carbon dioxide.
