Gas Exchange and Ventilatory Efficiency During Exercise in Pulmonary Vascular Diseases.

CONCLUSIONS: Resting hypocapnia is associated with worse cardiac function, more ventilatory inefficiency and reduced exercise capacity. This could be explained by elevated chemosensitivity and lower PaCO2 set-point. Maximal PETCO2 may be a useful non-invasive marker of PaCO2 setpoint and disease severity even with submaximal effort.
