This anesthetic and respiration gas monitoring unit is mainly for use in the operating room. This efficient device measures the respiratory gas concentration and continuously monitors levels of CO2, N20, O2 and volatile anesthetic agents. The GF-220R measures respiratory volume and continuously monitors the airway pressure, airway volume and the rate of airway flow. These fast measurements are produced in just 60 seconds after the device has been switched on. It can calculate the respiratory rate and identify the concentration of each component at exhalation and during inhalation. It automatically detects five anesthetic agents. Volatile anesthetics can be measured due to a sampling flow rate of 200 ml/minute which is useful when monitoring neonatals.
