One reason hospitals are so dangerous is that they leave carbon dioxide out of their protocols, except for a few types of surgery, making their oxygen use not only riskier but less effective. Surgeons pump CO₂ into the abdominal cavity to create working space and improve visibility. This is called CO₂ insufflation or a CO₂ pneumoperitoneum. It is used in procedures involving the gallbladder, colon, reproductive organs, and other abdominal structures.
