Through this interface, FSpO2 readings provided by an NPB Model N-400 are
printed at selected intervals on the strip chart paper of the 120 Series Monitor.
When the recorder is on, each reading is printed in the annotation area between the
top and bottom grids. A filled diamond marker, above the measured values, marks
the time of the reading and identifies the data source as an external device. The
following is an example annotation:
FSpO2 45%
In addition, the FSpO2 trend can be optionally printed on the bottom grid of the strip
chart paper; the trend is printed as a beaded trace ( ).
To connect the Model N-400:
1. Using interface cable, connect one end to an available
RS-232C port (J109,
J110, or J111) on the 120 Series Monitor; connect the other end to the
Serial
Communications
port on the pulse oximeter.
2. Access the Communications Setup service mode screen and set the baud rate
and mode for the appropriate port to 2400 and NELLCOR, respectively; then
exit the service mode screens.
3. Access the General Setup screen, then: choose the time interval for printing the
FSpO
2 values on the strip chart paper; and enable/disable trending of %FSpO2
on the bottom grid of the strip chart paper. Refer to “Chapter 5, Setup
Procedures”, in this manual for more detailed information.
4. Ensure the NPB N-400 is set to the Beat-to-Beat mode.
