What should you do until symptoms of hypoxia disappear?

B breathing at a rate slightly less than normal is the correct approach to managing hypoxia symptoms. When experiencing hypoxia, which occurs due to inadequate oxygen supply, it is crucial to optimize oxygen intake and maintain this critical balance. Breathing at a rate that is slightly less than normal can help ensure that the body retains carbon dioxide while facilitating oxygen absorption. This can prevent further exacerbation of hypoxic symptoms.

In contrast, breathing at a normal rate could fail to maximize oxygen exchange during this critical moment, while panicking and alerting crew members is not a productive response as it may lead to further stress and a decrease in overall situational awareness. Continuing with normal activities may also not be advisable, as it risks neglecting necessary self-monitoring and response to symptoms of hypoxia, potentially leading to more severe health complications. Overall, a measured approach to breathing is essential for recovery.
