Capnograph for Small Rodents (Type 340)
The Type 340 capnograph for rats and mice is equipped with a built-in highly sensitive infrared spectroscopy CO2 sensor. The sensor is pressure and temperature compensated. The very low volume of the sensor, the optimized system volume and the application of a micro-pump allow very accurate monitoring of respiratory CO2 concentration on small animals. The Capnograph also includes electronic compensation for interference introduced to signals during NO2 anesthesia administration.

- Analog output of CO2 waveform, end-tidal CO2, respiratory flow, tracheal pressure, respiratory rate and tidal volume in extended version
Applications
The main function of this unit is capnography. With the extension using additional sensors, it can become a complete respiratory survey and monitoring system for:
• Capnography
• Anesthesia survey
• Respiratory monitoring
Extended Functions (optional)
The Capnograph can be equipped with two additional sensors, a pressure sensor for measuring tracheal pressure and a pneumotach with differential pressure transducer for measuring respiratory airflow. These sensors are mounted directly on the tracheal or intubation cannula and connected to the control unit, this serves to minimize the dead space. The tracheal pressure and the respiratory flow are important signals to monitor during mechanical ventilation. When monitoring these parameters the investigator can verify that ventilation is performed within normal physiologic limits and helps to avoid barotraumatic ventilation conditions.
Settings
All the settings are done using the display and keypad on the front panel. The settings can also be downloaded by software via a RS232 (optionally USB) port on the back panel.
