abstract：:Acute sustained hypoxia causes an early rise in ventilation, followed by a reduction in ventilation ("roll off") after several minutes to levels below the peak but above baseline. The underlying mechanism(s) of this biphasic response is unclear. Hypoxia induces changes in the release and metabolic turnover of glutamat...
