Carbon Dioxide Flooding: A Classroom Case Study Derived from Surgical Practice  Robert C. Kerber
The surgical opening in open-heart surgery is often flooded with carbon dioxide gas to avoid air embolisms when the heart is closed and restarted. This practice can be used in chemistry courses to illustrate concepts of gas density, solubility, and acidbase equilibria, including buffering.
