Oridion Systems (SIX Swiss Exchange: ORIDN) develops technology for the detection and measurement of carbon dioxide (CO2) in exhaled breath. This is used for capnography, which monitors a patient's ventilatory status, and for the non-invasive diagnosis and monitoring of various conditions in specific internal organs. 

Exit: Oridion carried out an IPO on the SWX Swiss Exchange (now the SIX Swiss Exchange) in April 2000, when it raised $77M. Gemini no longer invests in medical device companies.
