5. Respiration
01 Respiration
Accuracy
With comprehensive tester or reference
respiration signal generator, input
sinusoidal waveform of 0.5Hz with base
resistance of 1.5k
Ω
/1
Ω
change.
The displayed amplitude
should be within
10mm±2mm.
02 Respiration Rate
Accuracy
Input reference respiration signal to
comprehensive tester or respiration
simulator, and check the respiration rate
display. Test with the respiration
reference load signal of 60, 120/min.* Error should be within
±5bpm.
03 Frequency
Characteristic*
With comprehensive tester or reference
respiration signal generator, input 0.5Hz
and 1.5Hz or 2.5Hz, and measure the
frequency characteristic. The crest value for the
following frequency should
be more than 70% of the
crest value at 0.5Hz input.
Adult Mode: 1.5Hz
Neonate Mode: 2.5Hz
* As these functions are dependent on the design or software, these items are not required for periodic
check. Perform the test as necessary.
No. Check Item Check Procedure Criteria
6. Temperature
01 Temperature
Accuracy
Input 20, 30, 40
°
C with comprehensive
tester, and check the error between the
displayed value.
Error should be within ±0.2
°
C
for the range within 0~50
°
C.
02 Temperature
Probe-Off Detection
Check the display by disconnecting the
probe. The displayed value should
disappear from the display.
No. Check Item Check Procedure Criteria
7. Non-invasive Blood Pressure
01 Automatic Check Connect the 500cc air tank.
Perform NIBP test on the test menu. Should pass all test items.
02 Pressure Accuracy Connect the mercury manometer or
sphygmomanometer and pressurize.
Measure the error with the displayed
NIBP value.
Measure at 120, 180mmHg. Error should be within
±4mmHg.
03 Measurement
Operation
Perform NIBP measurement on NIBP
simulator or on testee. Proper NIBP measurement
should be possible.
No. Check Item Check Procedure Criteria
8. Arterial Oxygen Saturation (SpO
2
)
01 SpO
2
Accuracy Measure the error at 75%, 90% using
the SpO
2
simulator.
Error should be within ±2%
for SpO
2
of 70%~100%.
Prepare other reference device,
perform measurement on healthy
subject, and compare the value.
Error between the 2 devices
should be within ±4%.
02 Pulse Detection
Range
Input 60, 200bpm using the SpO
2
simulator, and measure the error.
Error should be within ±3bpm
for 20~250bpm.
Prepare other reference device,
perform measurement on healthy
subject, and compare the value.
Error between the 2 devices
should be within ±6%.
03 SpO
2
Probe-Off
Detection
Check the display by disconnecting the
probe.
Waveform and numeric data
should disappear from the
display.
