Observational Study
Exercise intolerance in untreated obstructive sleep apnea: role of pulmonary gas exchange and systemic vascular abnormalities.
Reduced exercise capacity has been reported previously in patients with OSA hypopnea syndrome (OSAHS), although the underlying mechanisms are unclear. ⋯ Patients with OSAHS showed evidence of pulmonary gas exchange abnormalities during exercise (in the form of increased dead space) and resting systemic vascular dysfunction that may explain reduced exercise capacity and increased exertional dyspnea intensity.
