Question

Quizplus · Accepted Answer

Atelectasis, a condition characterized by the collapse of part or all of a lung, leads to reduced lung volume and capacity. This results in decreased Inspiratory Capacity (IC) and Vital Capacity (VC), as the lung's ability to expand is compromised. PEFR (Peak Expiratory Flow Rate) may also decrease due to reduced lung volume, but it is not a direct indicator of atelectasis. DLCO (Diffusing Capacity of the Lung for Carbon Monoxide) is not typically increased in atelectasis; it may decrease or remain unchanged depending on the extent and cause of the atelectasis.
