High Altitude Training College of Aviation

1. High Altitude TrainingCollege of Aviation Glenn Harmon, Aerospace Physiologist, Asst Professor of Aeronautical Science

2. 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?

3. Hypoxia Accidents

4. High Altitude Training Military Training FAA Oxygen Requirements Civilian and Airline Training DOT/FAA Study

9. 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

10. Instructor Training

11. Symptoms of Hypoxic Hypoxia • Tunnel vision, visual acuity, focus SUBJECTIVE • Euphoria, dizziness, tingling, headache • Fatigue, loss of coordination, slurred speech • Cyanosis, rapid breathing • Incapacitation • Death OBJECTIVE Menu

12. Participation in the High Altitude Lab At least 18 years of age. Hold at least a 2nd class FAA medical or equivalent. Medical Screening: For health and safety reasons, you must notify an instructor if you are currently experiencing any of the symptoms or conditions below: _______ Dizziness, fainting spells, unconsciousness or seizures _______ Eye or vision trouble (except corrective lens) _______ Heart or vascular trouble, or anemia _______ Upper respiratory infection, asthma or bronchitis _______ Chest pain or shortness of breath _______ Diabetes _______ Medications not approved for flight _______ Recent surgery _______ Pregnancy or you have other health concerns
