What type of hypoxia is characterized by insufficient oxygen due to low pressure in the lungs?

• A. Hypoxic Hypoxia
• B. Hystoxic Hypoxia
• C. Anaemic Hypoxia
• D. Stagnant Hypoxia

Answer: (A)

Hypoxic hypoxia occurs when there is a deficiency of oxygen in the blood due to inadequate oxygen availability, often linked to lower atmospheric pressure. This type of hypoxia is particularly relevant at high altitudes, where the decrease in air pressure results in a lower partial pressure of oxygen. Consequently, despite normal functioning lungs and circulation, the body cannot extract enough oxygen due to the diminished availability in the surrounding environment. In high-altitude environments, as pressure decreases, the amount of oxygen molecules available for breathing also decreases. As a result, pilots and individuals exposed to such conditions may experience symptoms of hypoxia, including dizziness, shortness of breath, and impaired cognitive functions. Understanding hypoxic hypoxia is crucial for pilots, as it emphasizes the need for supplemental oxygen in certain flight conditions to maintain adequate oxygen levels and function safely.
