Nellcor Puritan Bennett Model N-200
Maternal Pulse Oximeter
Through this interface, MSpO2 readings provided by an NPB Model N-200 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 data, marks the time of
the reading and identifies the data source as an external device. The following is an
example annotation:
MSpO2 97% P 78
When the recorder is in maternal-only mode, a time stamp and filled diamond mark
precede each reading. A sample annotation looks like this:
11:13 MSpO2 97% P 78
