CW-MRI-1 The CW-MRI-1 ventilator is a small animal ventilator designed for use in MRI and other highly magnetic field environments, though its use is not limited to those environments. It offers manual or remote operation of pneumatic, non-metalic valves. The CW-MRI-1 operates on the flow-time principle, dispensing a known airflow into the lungs for a set inspiratory time to generate desired tidal volumes. Three controls–respiratory rate, inspiratory time and flow rate–allow for accuracy and extraordinary flexibility over a wide range of volumes, breaths-per-minute and inspiration/expiration (I/E) ratios. The unit can be expanded to ventilate larger animals. A source of compressed air or helium is required for operating the pneumatic valves. CW-SAR1000 The CW-SAR1000 Small Animal Ventilator is a versatile and easy-to-use ventilator for mice, rats, and other small animals. Volume mode delivers a fixed tidal volume on each breath, and pressure mode causes inflation to stop at a preset airway pressure. In either mode, lung inflation is maintained at the end of inspiration until the percent inspiration (%Insp) time has elapsed. This end inspiratory pause (IEP) improves gas exchange and the overall efficiency of ventilation. In volume mode, the ventilator operates on the proven flow-time principle, where a known airflow is delivered for a set time, thus delivering a fixed volume. In pressure mode, airflow is simply adjusted to give a suitable inspiration time. Actual tidal volume is computed and displayedon the LCD display, as well as minute ventilation (MV) and other respiratory parameters. A built-in air pump allows completely self-contained operation. This pump draws in room air, oxygen, or anesthetic gasses through a rear-panel port.

(4.5kg) microCAPSTAR extends CO2 monitoring to the realm of small animals. The advanced features, reliability and ease of operation make it the perfect companion to the CW-SAR-830/AP small animal ventilator. Featuring low sample requirements, rapid response time and long-term stability, this CO2 analyzer provides accurate end-tidal or continuous measurement of expired CO2. The LCD screen displays CO2 concentration (instantaneous ETCO2 in either percent or mmHg), respiratory rate measurements and trend plot of the end-tidal values. An adjustable ETCO2 alarm warns when end-tidal values fall out of the user-adjustable preset range. Built-in diagnostics warn of plugged sample tubing or other fault conditions.
