The MicroSim COS, Cardiac Output Simulator is the only stand alone instrument designed to test the performance of thermal dilution cardiac output monitoring instruments. It simulates Baxter Edwards catheter systems and provides more testing capabilities than devices that require connection to another patient simulator.

Four blood flow rates, two blood temperatures and two injectate temperatures may be selected. A total of 32 normal curves and square waves are available to the user. Four tactile feel keys operate the instrument and LEDs indicate the test being performed. A power up self test indicates that the instrument is performing properly. It is powered by a 9 volt battery.

The simple to operate MicroSim COS is an accurate and powerful instrument in a small package.
