Response to Letter by Bailey
We thank Dr Bailey1 for his comments and do not take exception to them. As stated in our article, we also believe that methodological differences between studies make direct comparisons of cerebral autoregulation difficult. The main intent of our sentence quoted in Dr Bailey’s letter was simply to point out that previous studies had not measured changes in cerebral autoregulation before the onset of acute mountain sickness, “… making it difficult to draw conclusions regarding the role of impaired cerebral autoregulation in the development of acute mountain sickness.”2 Our study filled this gap in the literature. Ultimately, we agree that impaired cerebral autoregulation does not appear to be a causative factor in acute mountain sickness.
