RESUMEN

Las únicas intervenciones que han demostrado modificar la historia natural de la EPOC son 1) dejar de fumar y/o exponerse al humo de leña y 2) el uso de oxígeno suplementario en sujetos con hipoxemia. Aunque hay evidencia que la exposición crónica al humo de leña se asocia a EPOC, no hay estudios longitudinales con grupo control, que muestren que al dejar la exposición, disminuye la caída anual del FEV₁.
No se debe iniciar ningún tratamiento diferente si no se han revisado y satisfecho estas dos intervenciones.
