High Altitude Training

Purpose: Demonstrate the symptoms and effects of hypoxia and recovery using airline-style oxygen masks.

Hypoxia: Lack of oxygen in the blood or brain caused by low atmospheric pressure or content resulting in impairment or unconsciousness.

Is Hypoxia Awareness/Training Needed?

Typical Profile40-50 Minutes
  • Lab start-up and ascent to altitude e.g. 25,000 ft.
  • Students briefed on Objectives, Ops, mask usage
    • Enter - Don O2 masks, Comm, pulse oximeters
    • Review symptoms/discussion/accident recap
    • Select studs to remove mask, begin tasks
      • Studs identify 2-3 symptoms - 8-12 min– recover on O2
  • Student feedback
    • Subjective & objective symptoms
  • Exit lab – debrief
symptoms of hypoxic hypoxia
Symptoms of Hypoxic Hypoxia
  • Tunnel vision, visual acuity, focus SUBJECTIVE
  • Euphoria, dizziness, tingling, headache
  • Fatigue, loss of coordination, slurred speech
  • Cyanosis, rapid breathing
  • Incapacitation
