Which type of hypoxia could result if your aircraft depressurizes at altitude?

Hypoxic hypoxia occurs when there is a deficiency in the amount of oxygen available for breathing at high altitudes. In the scenario of an aircraft depressurizing at altitude, the reduced atmospheric pressure leads to a lower partial pressure of oxygen. As the aircraft climbs, the amount of oxygen available decreases, and if the cabin pressure is lost, passengers and crew may not receive sufficient oxygen, leading to this type of hypoxia. Symptoms can include confusion, lethargy, and impaired cognitive and physical performance due to the body's inability to oxygenate the blood adequately. Understanding the effects of altitude on oxygen availability is crucial for pilots to ensure they manage cabin pressure and prevent hypoxia in flight.
