Harvard Apparatus-HSE has introduced the Capnograph Model 340 for small rodents.
This low-volume capnograph measures end-tidal CO2 concentration with a sampling rate of 10ml/min.
This unit is suitable for use with mice and can be combined with any Harvard Apparatus-HSE rodent ventilators.
With the addition of the optional airflow and tracheal pressure sensor, the Capnograph Model 340 becomes a complete respiratory survey and monitoring system - providing peak inspiratory flow, peak expiratory flow, tidal volume, respiratory rate, and peak tracheal pressure.
Ideal for respiratory monitoring during surgical procedures, the Capnograph Model 340 can be used to verify the physiological parameters for mechanical ventilation and anesthesia delivery as well as monitor the general status of an animal's respiratory function. This capnograph features an infrared flow-through sensor for continuous CO2 measurement and a waveform display on an LCD. Airflow, tracheal pressure and CO2 measurements can be viewed as a phasic signal on respective BNC outputs End-tidal CO2, tidal volume and respiratory rate are available as analogue signals over three breaths on respective BNC outputs. For respiratory airflow measurement and monitoring, the Capnograph Model 340 features an integrated pneumotachometer with a differential-pressure transducer. It can be equipped with an additional pressure transducer for tracheal pressure if desired. To minimise dead space, the sensors are mounted directly on a tracheal or intubation cannula and are connected to the control unit.
