The GEMINI O2 & CO2 monitor uses high-performance sensor technology for accuracy, stability, and fast response. Digital CO2 and O2 sensors: CO2 is measured with a temperature-controlled miniature infrared analyzer cell; O2 is measured with a fast-response 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 color TFT 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.
Applications: The GEMINI monitor provides complete information for respiratory status assessment for animals as small as rats and as large as whales. Oxygen consumption measurements can be performed using a metabolic chamber (not included). It comes complete with an accessory pack of inlet tubing, connectors, and moisture filters.
The GEMINI Respiration Monitor measures CO2, O2, and respiration rate (RR) of spontaneously breathing or ventilated animals. It provides continuously updated and breath-by-breath readings as well as analog outputs for all measurements for external recording. Adjustable alarms signal out-of-range values for ETCO2 and RR. We're excited to introduce our new updated version of the GEMINI, with all of the same O2 & CO2 monitoring features that researchers rely on in an efficient, streamlined design, plus expanded capabilities like the new METABOLIC MODE (with slower, high-resolution measurement), adjustable SAMPLE PUMP speed, digital CO2 and O2 sensors, all-digital push-button controls, and automatic pressure correction of readings.
