3.3.2.4 Cuff Inflation Rate
The cuff inflation rate test verifies the inflation rate of the N-3100. Prior to
performing this procedure, the setup procedure in paragraph 3.3.2 must be
completed.
1.
Press the UP/DOWN ARROW buttons until menu item “31” is displayed
in the SYSTOLIC display.
2.
Press and release the UPPER ALARM LIMIT button.
3.
Press and release the START/STOP button. The simulator begins to
pressurize. The current pressure in mmHg is displayed in the
DIASTOLIC display.
4.
At the end of the test cycle, the simulator depressurizes and the
SYSTOLIC display indicates submenu item number “31.0.” The
DIASTOLIC display indicates the time in seconds, to the nearest tenth,
required to pressurize to 250 mmHg. A reading of 3.0–9.0 seconds
indicates successful completion of the test.
5.
Press the UP ARROW button to display menu item “31.1” in the
SYSTOLIC display. The DIASTOLIC display indicates the time in
seconds, to the nearest tenth, required to pressurize to 300 mmHg. A
reading of 4.0–9.0 seconds indicates successful completion of the test.
6.
Return to the service mode steady state by pressing the LOWER ALARM
LIMIT button.
3.3.2.5 Cuff Deflation Rate
The cuff deflation rate test verifies the deflation rate. Prior to performing this
procedure, the setup procedure in paragraph 3.3.2 must be completed.
1.
Press the UP/DOWN ARROW buttons until menu item “32” is displayed
in the SYSTOLIC display.
2.
Press the UPPER ALARM LIMIT button.
3.
Press the START/STOP button. The simulator begins to pressurize. The
current pressure in mmHg is displayed in the DIASTOLIC display.
4.
At the end of the test cycle, the simulator depressurizes and the
SYSTOLIC display indicates submenu item number “32.0.” The
DIASTOLIC display indicates the rate in mmHg per second, to the
nearest tenth, required to depressurize from 260 to 180 mmHg. A
reading of 4.6–6.2 seconds indicates successful completion of the test.
5.
Press the UP ARROW button to display menu item 32.1 in the
SYSTOLIC display. The DIASTOLIC display indicates the rate in mmHg
per second, to the nearest tenth, required to depressurize from 180 to
100 mmHg. A reading of 4.6–6.2 seconds indicates successful completion
of the test.
6.
Press the UP ARROW button to display menu item 32.2 in the
SYSTOLIC display. The DIASTOLIC display indicates the rate in mmHg
per second, to the nearest tenth, required to depressurize from 100 to
60 mmHg. A reading of 3.3–5.2 seconds indicates successful completion
of the test.
