GEMINI Respiratory Monitor

This instrument uses the latest sensor technology for accuracy, stability,  and fast response. CO₂ is measured with a temperature-controlled miniature infrared analyzer cell; O₂ is measured with a new paramagnetic sensor cell. Respiratory rate is computed using the normal excursion of the CO₂ signal, and is updated on each breath.

Simple set up and operation: The sample inlet tubing is connected to the endotracheal tube as close to the animal as possible. High and low alarms are set using a single knob, and the settings are stored in non-volatile memory so they do not have to be reset the next time the instrument is used. All measurements are displayed on the front panel LCD display, and are available as analog voltages for external recording. In addition, a serial port provides all the measurements in a simple ASCII format for collection by any computer.

Expandable: An open slot is provided for installation of any SYSTEM 1000 instrumentation module. Available modules include a cardiotachometer (Model CT-1000), blood pressure amplifier (Model PM-1000), plethysmographic respiration monitor for very small animals (Model RR-1000), and many other functions. This expandability allows you to configure a complete physiological monitor for use during surgery or extended experiments.

Applications: The GEMINI monitor provides complete information for respiratory status assessment for animals as small as rats. It comes complete with an accessory pack of inlet tubing, connectors, and moisture filters.
