9. Invasive Blood Pressure
01 BP Accuracy Input 0, 100, 200mmHg with
comprehensive tester, and measure
the error between the displayed value
and input value. Error should be within (full
scale, 300mmHg) ±2% or
±1mmHg whichever is larger.
02 Pulse Detection
Accuracy*
Input 30, 120, 160bpm with
comprehensive tester, and measure
pulse rate error. Pulse rate error should be
within ±3%.
03 BP Probe-Off
Detection
Check the display by disconnecting the
probe. Waveform and numeric data
should disappear from the
display.
No. Check Item Check Procedure Criteria
10. Cardiac Output (CO)
01 CO Accuracy Measure the error by inputting 5L/min.
and 15L/min. using a waveform
simulator or CO simulator. Should be within 0.1–10L/min
±10%.
Should be within 10–20L/min
±15%.
Measure the error by connecting the
waveform simulator or CO simulator,
and inputting the blood temperature of
36
°
C, 37
°
C, and 38
°
C.
Should be within ±0.3
°
C for
the blood temperature of
17–45
°
C.
02 Temperature
Accuracy
Measure the error by connecting the
waveform simulator or CO simulator,
and inputting the injectate temperature
of –1
°
C, 35
°
C.
Should be within ±0.5
°
C for
the injectate temperature of
–1–35
°
C.
03 CO Probe-Off
Detection
Check the display by disconnecting
the probe. Numeric data should
disappear from the display.

11. Multigas Unit (O
2
)
01 O
2
concentration Check the error margin using the 80%
calibration gas. Should be within 80%±1%
02 Water Trap Disconnect the water trap from the
unit. "Insert Water trap"
message must be
displayed.

12. External Output (Analog Output)
01 ECG Output
Sensitivity
Perform ECG input by comprehensive
tester.
Connect the oscilloscope to the output
and observe the waveform. Should be within 1V±10% for
the 1mV input.
Should be within ±0.5V for
the 0mV input.
02 BP Output Sensitivity Perform BP input by comprehensive
tester.
Connect the oscilloscope to the output
and observe the waveform.
Should be within 1V±10% for
the 100mmHg input.
Should be within ±20mV for
the 0mmHg input.
