3. The N5500 displays pressure of approximately 290 mmHg automatically.
4. The test result displays at the test completion. The initial pressure value at 1 minute
is displayed after the test start and the air leakage value at further 3 minutes after the
1 minute elapsed.
Note: The test will have been successfully completed if the pressure has dropped by 6
mmHg, or less, during the 1-minute period.
3.3.5.2.4 Inflation Time Measurement
The inflation time test verifies the inflation time of the N5500.
1. Ensure the monitor is set up with Rigid cuff can.
2. Ensure NIBP Test screen is active on N5500, then select “Inflation Time
Measurement” by the knob.
3. The N5500 displays pressure of approximately 290 mmHg automatically and
measures inflation time in seconds.
4. The test result displays at the test completion.
Note: The test will have been successfully completed if the inflation time is 4.0 to 7.5
seconds (to 250 mmHg).
3.3.5.2.5 Deflation Rate Measurement
The deflation time test verifies the deflation rate of the N5500.
1. Ensure the monitor is set up with Rigid cuff can.
2. Ensure NIBP Test screen is active on N5500, then select “Deflation Rate Test” by the
knob.
3. The N5500 displays pressure of approximately 290 mmHg automatically, then
measures deflation rate during reducing the pressure.
4. The test result displays 4 parts (from 260-180mmHg, 180-100mmHg, 100-60mmHg
and 60-30 mmHg) at the test completion.
5. Confirm the result is within the specification.
- 260-180mmHg : 4.8 ~ 6.0 mmHg/s
- 180-100mmHg : 4.8 ~ 6.0 mmHg/s
- 100-60mmHg: 3.5 ~ 5.0 mmHg/s
- 60-30 mmHg : 2.8 ~ 4.2 mmHg/s
