May inform hypoxia tolerance assessments in HA natives at SL; leaves open mechanisms of persistent ventilatory adaptation.
Does high-altitude native status affect acute and sustained ventilatory responses to hypoxia when living at sea level?
High-altitude natives living at sea level exhibit persistent blunting of ventilatory responses to sustained hypoxia, with less pronounced blunting to acute hypoxia.
Gamboa et al. (2003) studied this question.
