Are there any breathable liquids?
Breathable liquids, also known as liquid breathing, involve the use of special fluids that allow gas exchange to occur through the liquid. One notable example is perfluorocarbons (PFCs). PFCs possess high solubility for oxygen and carbon dioxide, making them suitable for respiratory support. When a person breathes in a PFC, oxygen dissolves in the liquid, and it can be transported to the lungs and other tissues. This method has been explored for potential applications in medical settings, particularly for patients with respiratory failure. One challenge in liquid breathing is managing the physiological and technical complexities. The liquid must have appropriate physical properties to support respiration while avoiding harm to lung tissues. Researchers are actively investigating ways to optimize PFC formulations and delivery methods. Despite promising advancements, practical implementation in medical practice is limited, and liquid breathing remains more of a research area than a widel...
