Hypoxia
What is the most common type of hypoxia in aviation?
Hypoxic Hypoxia
3 types of Supplemental Oxygen
Continuous-flow oxygen
Diluter-demand oxygen
Pressure-demand oxygen
What is a mental symptom of hypoxia?
Euphoria
occurs when a pilot breathes too rapidly or deeply
Hyperventilation
What type of hypoxia is caused by alcohol or carbon monoxide poisoning?
Histotoxic Hypoxia
Which oxygen system is commonly used for passengers in general aviation aircraft?
Continuous Flow Oxygen System
Which physical sign of hypoxia causes a bluish discoloration of the lips and fingertips?
Cyanosis
What is the most common cause of hyperventilation in pilots?
Anxiety or Stress
Which hypoxia occurs due to poor circulation, like from G-forces?
Stagnant Hypoxia
At what altitude must pilots use supplemental oxygen if flying for more than 30 minutes?
12,500 ft
How long does useful consciousness last at 25,000 feet without supplemental oxygen?
3-5 mins
What are the treatment of Hyperventilation?
Control breathing, Manage anxiety and stress, Use Oxygen correctly
What is the best way to prevent hypoxia at high altitudes?
Supplementary Oxygen
What type of oxygen system is used in high-altitude commercial airliners?
Pressure Demand
What tool helps pilots monitor their blood oxygen levels?
Pulse Oximeter
What should a pilot do if they are unsure whether they are experiencing hypoxia or hyperventilation?
Use supplemental oxygen immediately.
Why is a pulse oximeter useful for pilots?
monitors blood oxygen levels, helping detect early signs of hypoxia
What ICAO regulation requires oxygen use at high altitudes?
PCAR 8.5.1.25
Explain the difference between Hypoxia and Hyperventilation
Hypoxia - High altitude, cabin pressure failure, failure to use supplemental oxygen
Hyperventilation - Stress, anxiety, fear, improper oxygen use, rapid breathing
What is a major difference between hypoxia and hyperventilation?
Hypoxia - low oxygen
Hyperventilation - low CO2
