3.3.1.3 Power-On Defaults for Neonatal Alarm Limits and Ranges
Note:
The following procedure is written using Nellcor Puritan Bennett
factory-set power-on default settings. If your institution has other
custom power-on default settings, those values will be displayed and
should be substituted in the following procedure. The N-3100 can be
reset to factory power-on defaults using the service mode procedure
described in Paragraph 4.3.11, Menu Item 20, or configuration mode,
as described in Paragraph 4.2.13, Configuration Menu (item 3).
In the following procedures, each time the UPPER ALARM LIMIT
button or the LOWER ALARM LIMIT button is pressed, the N-3100
will emit a beep.
When observing or changing default limits, a 3-second timeout is in
effect, i.e., if no action is taken within 3 seconds, the monitor
automatically returns to the normal operating mode steady state.
The following procedures use the N-3100 UP and DOWN ARROW
buttons located on the top of the monitor. When the N-3100 is
stacked with the N -3000, the Nellcor knob on this unit can be used to
perform the function of the N-3100 UP and DOWN ARROW buttons.
Turning the Nellcor knob in a clockwise direction is equivalent to
pressing the N -3100 UP ARROW button. Turning the knob in a
counterclockwise direction is equivalent to pressing the N-3100
DOWN ARROW button. There will be no sounds or beeps associated
with turning the knob. When the N-3100 is stacked with the N -3000,
the UP and DOWN ARROW buttons are not accessible and the
Nellcor knob must be used.
1.
Press the ON/STANDBY button to turn the unit on. Verify that the
N-3100 is in the neonatal mode, which is indicated by the NEONATAL
MODE indicator being lit. If the indicator is not lit, quickly press and
release the NEW PATIENT/NEONATAL button twice to place the
N-3100 in the neonatal mode. When the unit is in the normal mode
steady state, press and release the UPPER ALARM LIMIT button.
Verify that the monitor emits a single beep when you press the UPPER
ALARM LIMIT button. Verify that the SYSTOLIC display indicates an
alarm limit value of “120” for a few seconds and verify that the other
displays show dashes at the top while the “120” is displayed. Do not
press any buttons for at least 3 seconds and all displays will change to
show a dash in the center of each character (normal mode steady state).
2.
From the normal mode steady state, press and release the UPPER
ALARM LIMIT button. Press and hold the DOWN ARROW button until
“50.” is displayed the SYSTOLIC display.
Note:
A period (“.”) following a displayed alarm limit value is an
indication that the alarm limit value has been changed from the
power-on default value previously set in the N -3100.
3.
From the normal mode steady state, press and release the LOWER
ALARM LIMIT button. Verify that the monitor emits a single beep when
you press the button. Within 3 seconds, verify that the SYSTOLIC
display indicates an alarm limit value of “50” (the default systolic lower
alarm limit) and verify that the other displays show dashes at the bottom
while the “50” is displayed.
