A patient wears FIDO over their mouth and nose. When they exhale, air is filtered through a limestone cartridge, which collects most of the CO2. An attached balloon collects and recirculates the exhaled air, mixing it with oxygen from the attached canister. When the patient inhales, the air is once again passed through the limestone cartridge.
