One could speculate that the persistent functional limitation seen after infection may originate in the respiratory system, a fact reinforced by studies that showed ventilatory limitation in spirometry after hospital discharge.,
Cardiopulmonary Exercise Test (CPET) allows a complete assessment of the cardiorespiratory system. It is the gold standard exam to define prognosis in several heart and lung diseases and can discriminate the underlying mechanisms associated with reduced functional capacity.,
