MEDREH-02 · Pulmonary Rehabilitation

Pulmonary Rehabilitation. Topics: PFTs, COPD Classification, Oxygen Therapy, Ventilator Weaning, and Tracheostomy. Part of the Medical Rehabilitation series of the Reflex PM&R Board Review podcast. Audio correction: In the audio: a variable extra-thoracic obstruction, something like bilateral vocal cord paralysis, that flattens the inspiratory limb only. — Correct: Research reversal (2026-09-08): Vocal-fold paralysis, including bilateral paralysis, can produce variable extrathoracic obstruction. Laterality alone does not establish a fixed versus variable flow-loop pattern; correlate the functional pattern with laryngoscopy. The earlier unilateral-only correction is superseded. This transcript-derived wording is not shown wrong solely because it names bilateral paralysis; no audio listening or cutover was verified. The written chapter is correct.
