A reduction in cerebral oxygenation may contribute to brain swelling and neurovascular headache (Bailey et al. 2005) which in severe cases may progress to pulmonary oedema. This suggests that remote pulmonary complications may have a neurogenic basis. The present study combined exercise and hypoxia to effect changes in cerebral oxygen (O2) delivery and examined implications for cerebral autoregulation and pulmonary function in individuals susceptible to hypoxic headache (HHS) compared to those who are resistant (HHR).
