Small Animal Ventilators

CWE, Inc. has pioneered many innovations in the area of small animal ventilation. These range from the basic SAR-830 Series of volume and/or pressure-cycled models for routine maintenance of small animals, to computer-controlled models for specialized applications. 

All CWE ventilators operate on the flow-time principle. This method uses a constant flow of gas, which is gated into the animal for a known time, thus producing a known volume (flow x time = volume). This simple but powerful approach gives great flexibility in setting ventilation parameters such as inspiration time, I/E ratio, and more; something that is difficult or impossible to accomplish with the older mechanical piston-pump technology. In addition, this contributes to the legendary reliability and long service life of our ventilators, since the only moving parts are a pair of long-life solenoid valves. 

SAR-830 Series Small Animal Ventilators:

SAR-830/AP Ventilator (click picture for info) These are our most popular models, and provide reliable and safe ventilation of rodent-size animals. Inhalational anesthesia (Halothane or Isoflurane) is available for all models. Economical multi-animal setups are made easy by adding external valve assemblies. All models feature a built-in computer control interface for remotely-controlled applications. (Model SAR-830/AP shown at left)


Specialized Ventilators:

MR-compatible ventilators

MRI-1 Volume Ventilator (click picture for info) This unique series is designed for use in high magnetic field imaging applications. The MRI-1 Volume Ventilator uses remote, non-magnetic, pneumatic valves for controlling the animal's airflow. Pneumatic valve sets are available for animals ranging from mice to pigs. Anesthesia is available as an option.
 

Anesthesia for above ventilators:

Anesthesia setups (click picture for pdf data sheet) CWE offers complete Isoflurane and Halothane anesthesia kits for all of our ventilators. A simple system consists of an external flowmeter and vaporizer. Complete rebreathing systems with stands are also available.
