No Check Item Check Procedure Criteria
5 Respiration
01 Respiration display
sensitivity
Input 0.5Hz sinusoidal wave whose base
resistance changes 1.5k
Ω /1 Ω using the
comprehensive tester or reference
respiration signal generator and check the
displayed amplitude.
Displayed amplitude
should be within 10mm
±2mm.
02 Respiration Rate
display accuracy
Input the reference respiration signal with
comprehensive tester or respiration
simulator and check the respiration rate
display.
Test at respiration reference load signal in
60 or 120 per minute.
*Note
Measurement error
should be within ±5bpm
or less.
03 Frequency
Characteristic
*1
Input 0.5Hz, 1.5Hz, or 2.5Hz from the
comprehensive tester or reference
respiration signal generator and measure
frequency characteristic. To the crest value when
0.5Hz is inputted, the
crest value should be
70% or more when the
frequencies are as
follows.
*Note
: Since functional performance depends on design or software, these items are not required items in
maintenance check. Test if necessary.
No Check Item Check Procedure Criteria
6 Temperature
01 Temperature
display error
Input temperature 20, 30, or 40 °C to the
comprehensive tester and calculate the error
to displayed value. Should be within ±0.1°C
between 25°C and 45°C.
02 Temperature
Probe off
detection
Check the display by connecting and
disconnecting the probe. Displayed numeric should
disappear.
No Check Item Check Procedure Criteria
7 Non-Invasive Blood Pressure
01 Automatic check Connect 500cc air tank.
Conduct NIBP test in Test Menu. Pass all items.
02 Static Pressure
Accuracy
Connect a mercury manometer or
sphygmomanometer, increase pressure,
and measure the difference from the
displayed pressure.
Measure at 120mmHg and 180mmHg. Error should be within
±3mmHg.
03 Measuring
operation
Perform NIBP simulator or BP measurement
on the subject. BP can be measured.
No Check Item Check Procedure Criteria
8 Arterial Oxygen Saturation (SpO
2
)
01 Oxygen Saturation
Display Accuracy
Measure error by 75% and 90% using
SpO
2
simulator.
SpO
2
error should be within
±
2%.
Measure healthy people using other
reference equipment and compare the
numeric data.
Error between two devices
should be within ±4%.
02 Pulse detection
range
Input 60 and 200bpm using SpO
2
simulator and measure pulse rate error.
Error should be within
±3bpm or less.
Measure healthy people using other
reference equipment and compare the
numeric data.
Error between two devices
should be within ±6ppm .
03 SpO
2
Probe off
detection
Check the display by connecting and
disconnecting the probe. Waveform and numeric
data should disappear.
