A patient is being considered for participation in a pulmonary rehabilitation program. Which of the following pulmonary function tests would you recommend be performed as a component of the preliminary evaluation?
1) Lung volumes, including functional residual capacity (FRC)
2) Diffusing capacity (DLCO)
3) Pre- and post-bronchodilator flows
4) Lung and thoracic compliance

Pulmonary rehabilitation programs aim to improve exercise tolerance, reduce dyspnea, and enhance overall quality of life in patients with chronic respiratory diseases. Pulmonary function testing is an essential component of the preliminary evaluation to determine baseline lung function and assess the effectiveness of the rehabilitation program. The recommended tests to be performed include 1) Lung volumes, including functional residual capacity (FRC), to assess the extent of air trapping and hyperinflation; 2) Diffusing capacity (DLCO) to evaluate gas exchange efficiency; and 3) Pre- and post-bronchodilator flows to determine the presence of reversible airway obstruction. Lung compliance also provides information about the lung's ability to stretch and recoil, making Test 4 an essential part of the evaluation. Therefore, choices A, C, and D are not correct, and choice B is the best answer.
