The ventilatory effects of sustained isocapnic hypoxia during exercise in humans.

Abstract:

To investigate how the ventilatory response to isocapnic hypoxia is modified by steady-state exercise, five subjects were studied at rest and performing 70 W bicycle exercise. At rest, isocapnic hypoxia (end-tidal PO2 50 Torr) for 25 min resulted in a biphasic response: an initial increase in ventilation was followed by a subsequent decline (HVD). During exercise, an end-tidal PO2 of 55-60 Torr was used. The magnitude of the initial ventilatory response to isocapnic hypoxia was increased from...
