Do Submariners Breathe Pure Oxygen? Discover the Truth

Learn the truth about submariners' breathing mix and air quality management underwater.

0 views

Submariners do not breathe pure oxygen. Instead, they breathe a carefully controlled mix of gases, primarily similar to atmospheric air, which contains about 21% oxygen and 78% nitrogen. The air quality is continuously monitored and adjusted to ensure it remains safe for prolonged periods underwater. This helps maintain proper physiological function and prevents issues such as oxygen toxicity, which can occur if pure oxygen is breathed for extended durations.

FAQs & Answers

  1. What kind of air do submariners breathe? Submariners breathe a controlled mix of gases similar to atmospheric air, mainly composed of 21% oxygen and 78% nitrogen.
  2. Why can't submariners breathe pure oxygen? Breathing pure oxygen can lead to oxygen toxicity and other physiological issues, which is why a mixture is used.
  3. How is air quality managed on submarines? The air quality on submarines is continuously monitored and adjusted to ensure it remains safe for extended underwater missions.
  4. What risks do submariners face regarding breathing? Submariners face risks like oxygen toxicity and difficulties in maintaining proper air pressure and quality during long missions.
