Which of the following is true about hypoxia in relation to altitude?

• A. It does not occur at low altitudes
• B. It can occur at any altitude
• C. It is only a concern over 10,000 feet
• D. It impacts performance at levels below sea level

Answer: (B)

The assertion that hypoxia can occur at any altitude is accurate because hypoxia, defined as a deficiency in the amount of oxygen reaching the tissues, is influenced by various factors, including altitude and individual physiological responses. While the risk of hypoxia significantly increases with altitude due to diminishing atmospheric pressure and the resulting lower oxygen availability, it is incorrect to state that it exclusively occurs only at higher altitudes or above specific thresholds. Factors such as individual altitude acclimatization, exercise level, or underlying health conditions can cause hypoxia symptoms to manifest even at lower altitudes. Additionally, some individuals may experience hypoxia symptoms at moderate altitudes if unaccustomed to the conditions or if they exert themselves physically. Thus, the understanding that hypoxia can potentially occur at any altitude helps highlight the importance of awareness and preparedness when traveling to different elevations, as well as the variability of individual responses to changes in oxygen availability.
