The HSE Capnograph Type 340 Item 73-3809.  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.

Application:

The canpnograph has been developed specially for the measurement of the end-expiratory CO₂ concentration in expired air of rodents as well as respiratory parameters. The capnograph consists of the main instrument, with display, to measure end tidal CO₂ (ETCO₂) concentration in the expired air. Adding the tracheal pressure and air flow sensor you can expand the functionality to include peak inspiratory flow (PIF), peak expiratory flow (PEF), tidal volume (TV), respiratory rate (RR) and peak tracheal pressure (TP) can be measured.
