Revision C 250cx Series Maternal/Fetal Monitor 11-9
2036946-001
Recorder Modes: Annotations
Maternal Pulse Oximetry Annotations
A maternal pulse oximetry reading prints according to the interval time set on the
MSpO
2
Setup screen (for built-in parameter) or the General Setup screen (for external
device). For the built-in parameter, a reading also prints for each alarm generated.
The reading can print on any of the first three annotation lines—depending on which
printing line is available. A diamond marks the time of the reading.
: An unfilled diamond indicates the reading was received from the monitor’s
built-in maternal pulse oximetry parameter. The vital signs print below the
diamond.
: A filled diamond indicates the reading was received from an external
maternal pulse oximeter connected to the 250cx Series Monitor. The vital signs
print below the diamond. (Contact your Service Representative for connectivity
information.)
If the top three printing lines are busy printing other data, the diamond prints at the
time of the reading; however, the vital signs data prints as soon as a line becomes
available.
The pulse rate value determined by MSpO
2 always prints along with MSpO2.
Annotations from a Central Information System
The 250cx Series Monitor has three built-in RS-232C ports which can be used to
connect to a central information system which supports Hewlett Packard’s Digital
Series Protocol. Contact your Service Representative for more information.
The 250cx Series Monitor can also be configured via a communications service
screen to print annotations received from a central information system. A computer
marker prints on the bottom two lines of the heart rate grid marking the time the
annotation was made from a remote location if the central station has the capability
to send that command. See Figure on page 11-10.
Multiple Annotations
Sometimes annotations occur within seconds of each other. Consider the following
example shown in Figure on page 11-10:
an automatic NIBP reading occurs at 16:51:30
three annotations are received from a central information system; the entries are
made between 16:51:40 and 16:52:00
a manual NIBP reading occurs at 16:52:10
