Disnea de esfuerzo, deterioro del patrón ventilatorio y mala tolerancia al ejercicio: ¿signos precoces de insuficiencia respiratoria?

Apparently healthy subjects, whose spirometry are normal, complain of exertional dyspnea associated with a combination of adverse effects of: increased central ventilatory demand, overbreathing, impairments of ventilatory pattern, hypoventilation, and severe reduction of the maximal levels of exercise. These changes are not often explored, although they are potentially susceptible to correction corrected with sophisticated respiratory physiotherapy and exercise training.
