The GEMINI Respiration Monitor measures CO2, O2, and respiration rate of spontaneously breathing or ventilated animals. It provides breath-by-breath readings for end-tidal CO2 and O2, and instantaneous respiratory rate (breaths/minute). Adjustable alarms are provided to monitor CO2 and respiratory rate. 

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 an
