Atelectasis can cause a shunt-producing ventilation-perfusion mismatch.Which pathophysiologic mechanism explains how this occurs?

Question

Quizplus · Accepted Answer

A shunt-producing ventilation-perfusion mismatch is one in which perfusion exceeds ventilation.Whereas situations in which ventilation exceeds perfusion V/Q greater than 0.8 are considered to be dead space producing,situations in which perfusion exceeds ventilation V/Q less than 0.8 are considered to be shunt producing.
