Abstract

Ventilatory acclimatization to hypoxia (VAH) is the time-dependent increase in ventilation that occurs in mammals (including humans) during prolonged exposure to hypoxic environments. Goats acclimatize rapidly, reaching a ventilatory plateau within 4–6 hours of breathing hypoxic gas (Engwall & Bisgard, 1990). Evidence strongly suggests that VAH is caused by a time-dependent increase in carotid body (CB) sensitivity to hypoxia in goats (Nielsen et al, 1988). However, the mechanism for increased CB hypoxic sensitivity remains unknown.
