Question

Quizplus · Accepted Answer

Atelectasis is the collapse of part or all of a lung, leading to decreased gas exchange and ventilation in the affected area. This condition does not result in a normal shunt fraction; instead, it increases the shunt fraction due to the mismatch of ventilation and perfusion. Whispered pectoriloquy, an increase in the loudness of whispering noted during auscultation, can occur due to the lung consolidation associated with atelectasis. A chest radiograph will show increased density in areas of atelectasis due to the collapse of alveolar spaces. Diminished breath sounds are also characteristic of atelectasis because air movement is reduced in the collapsed areas of the lung.
