So needless to say, he is extremely qualified to dive into the understanding of High Altitude Sickness. In this episode we will cover:

  • Can I train for altitude?
  • Should I take Diamox? (Most people take 125 mg once in morning/once in the evening)
  • What are the side effects of taking it?
  • Is it common for people to get light level altitude at the beginning of their adventures, stop, sleep, hydrate and continue?
  • How fast oxygen from a canister can treat severe altitude sickness.
  • Pathophysiology of high altitude: AMS, HACE, and HAPE   The physiology portion is important in understanding the “why” of the pathology, avoidance, and treatment
  • And finally come stories from the trails.
