"Exploring the Feasibility of Human Liquid Breathing for Oxygen Intake"
Liquid breathing, the concept of breathing in oxygen-rich liquids, has been tested on animals and humans and is used clinically to provide oxygen to patients during mechanical ventilation. While it has potential benefits for deep sea divers and astronauts facing excessive G-forces, challenges such as impaired carbon dioxide elimination and the difficulty of mechanically ventilating someone in space remain. Although the concept has been explored in various works of fiction, its practical application outside of medical use presents significant hurdles.
