Maternal Heart/Pulse Rate Monitoring: MHR/P Source
MHR/P Source
The MHR/P can be determined by the MECG, MSpO
2
, and NIBP sections of the
monitor. However, the data from only one parameter is:
„
referred to as the MHR/P source
„
displayed in the MHR/P area;
„
used to evaluate an MHR/P alarm condition; and
„
used to generate the MHR/P trace on the strip chart paper.

The source is:
„
selected via the MHR/P Setup screen
„
may be manually selected or automatically selected by the monitor according to
the following priority order:
‹
MECG (values updated continuously)
‹
MSpO
2
(values updated continuously)
‹ NIBP (NIBP is available only as an
Auto
selection; the
Manual
selection is
disabled. Values updated only when NIBP determinations are taken)
IMPORTANT:
MSpO
2
AS AN MHR/P SOURCE—If MSpO
2
is selected as the
MHR/P source, an MHR/P alarm only occurs if the pulse rate
value derived from the MSpO
2
sensor violates an MHR/P alarm
limit. The MHR/P values derived from the MECG and NIBP
sections of the monitor are ignored. The heart rate tone varies in
pitch to reflect changes in the maternal oxygen saturation reading.
The pitch rises as the saturation values increase, and lowers as the
saturation values decrease. The pulse rate trend is a grey line
annotated by
MSpO
2
P .

If NIBP is selected as the MHR/P source, there is no trending of the data since these are static
measurements.
