3.3.7 C.O. Test
Tools required:
 Medsim300B patient simulator or other equivalent simulator
 C.O. adapter box (for 300B)
1. Connect the patient simulator to the C.O. module using a C.O. main cable.
2. Set the blood temperature (BT) to 37ºC on the patient simulator and check the temperature value is
37±0.1ºC.
3. Switch off Auto TI and adjust TI (IT) to 24ºC. Select C.O. Measure to enter the C.O. measurement
window and set Comp. Const. to 0.595.
4. Set the injectate temperature to 24ºC and the C.O. to 5 L/min on the C.O. simulator. Select Start in
the C.O. measurement window to start C.O. measurements, and press the run key on the simulator
after 3-10 seconds.
6. Verify that the C.O. value is 5±0.25 L/min.
