Columbuis CIV101 Ventilator

Columbus Instruments Ventilator CIV-101 is a precise respirator that allows a wide range of sizes suited to rats, rabbits, cats and other animals up to 10kg. To achieve the highest possible accuracy, tidal volume is divided into six(6) ranges by using piston/cylinder assemblies (0.5cc, 2.0cc, 5.0cc, 15.0cc and 50.0cc, and 100cc). Each precision glass cylinder is easily interchanged and the associated graphite piston never requires lubrication. Respiration Rate (BPM) is adjustable from 5 to 200 BPM in one BPM increments during operation without interruption of the experiment. CIV-101 will respond within 5 seconds of the request. Unique to CIV-101 is its ability to instantly change respiration rate. CIV-101 supports changing the relationship between inspiration and expiration time (I/E Ratio) during operation in increments of 0.01 over the range .25 to 4.0. The internal processor calculates the required changes in timing without altering the tidal volume or respiration rate settings.

During operation, the cylinder draws a precise volume of room air (or a non-explosive user supplied gas) then delivers it to the subject. The exhaled volume from the subject (returned by the elastic action of the lung) is vented through an exhaust port that may be collected for analysis.

CIV-101 employs a very high torque stepper motor that allows near instantaneous control of piston position and rate. This unique capbility allows stop and start control at any point for 'blur-free' imaging of the subject. Stop/Start control may be initiated by a remote switch or by front panel control.
