Eagle Eye Anesthesia is proud to offer Masimo EMMA Capnographs. Using a Capnograph is a non-invasive way to measure (during inspiration and expiration) the partial pressure of CO2 from the airway. The Capnograph is used as a monitoring tool for use during anesthesia care and gives you the numerical value of EtCO2. Normal range for cats is 32-35mm Hg and for dogs it is 35-46mm Hg.
