What is a good way to preserve oxygen while awaiting rescue from within a shelter facility?

• A. Lay down and be quiet; Don't exert yourself; Stay calm and collected
• B. Run around to stay active
• C. Remove your mask to breathe easier
• D. Shout for attention

Answer: (A)

Preserving oxygen in an enclosed shelter hinges on reducing how much oxygen your body uses. Laying down and staying quiet helps you lower energy expenditure and slow your breathing, so your cells consume oxygen more slowly while you wait for rescue. Keeping calm minimizes stress and avoids rapid, shallow breathing that can waste oxygen and raise carbon dioxide levels. In this situation, conserving energy and breathing steadily is more important than staying active or shouting. Running around uses more energy and increases oxygen demand, making your supply deplete faster. Removing your mask can expose you to contaminants and doesn’t create more breathable air. Shouting also increases energy use and breathing rate, which is undesirable when oxygen is limited.
