Nellcor Puritan Bennett Model N-400 Fetal Pulse Oximeter
NOTE: The Model N-400 monitor
is not available in all countries.
Through this interface, FSpO
2
readings provided by an NPB Model N-400 are
printed at selected intervals on the strip chart paper of the 250cx 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:
FSpO

In addition, the FSpO
2
trend can be optionally printed on the bottom grid of the strip
chart paper; the trend is printed as a beaded trace ( ).
