rebreathers
Rebreathers are specialized breathing devices used primarily in diving or hazardous environments that recycle exhaled air. When you breathe out, the device removes carbon dioxide and adds fresh oxygen, allowing you to breathe for longer periods without constantly exchanging the air. This efficiency reduces the amount of gas needed and minimizes bubbles, making it useful for underwater exploration or stealth operations. Rebreathers require careful monitoring and maintenance to ensure safety, as the recycled air depends on precise chemical processes and equipment functionality to prevent dangerous buildup of carbon dioxide or oxygen levels.
