3.4.7 C.O. Test
Tools required:
Medsim300B Patient simulator
C.O. adapter box
Follow this procedure to perform the test:
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. Set [Auto IT] to [Off] and adjust [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 5L/min on the C.O. simulator.
Select [Start] in the C.O. measurement window to start C.O. measurements and after
3-10 seconds press the run key on the simulator.
5. Check the C.O. value is 5±0.25L/min.
3.4.8 Mainstream CO

Tests
NOTE
z Make sure that the barometric pressure set in [Maintain CO
2
>>] of [User
Maintenance>>] accords with the local barometric pressure before performing
mainstream CO
2
tests.
Tools required:
A steel gas cylinder with 6±0.05% CO
2
A steel gas cylinder with compressed air or N
2
(with standard concentration)
Two 3-way valves (power supply controlled)
Flowmeter
Power supply
Tube
Follow this procedure to perform the test:
1. Wait until CO
2
warmup is finished and then select [Start Zero Cal.] from [CO
2
Setup]
menu to start a zero calibration. If the zero calibration fails, the prompt message [CO
2
Zero Failed] is displayed. Otherwise, the baseline of waveform recovers to zero.
2 Set [Apnea Time] to 10 s in the [Adjust CO
2
Limits] menu.
