Question

Quizplus · Accepted Answer

DLCO and Total Lung Capacity (TLC) are most useful in determining the need for pulmonary rehabilitation in patients with restrictive lung disease. DLCO assesses the lung's capacity to transfer gas from air to the blood, important in restrictive diseases. TLC measures the maximum amount of air the lungs can hold, which is reduced in restrictive lung disease. FEV1/FVC ratio is more relevant in diagnosing and assessing obstructive lung diseases.
