Maternal Pulse Oximetry Monitoring: Module and Probe Compatibility
MSpO
2
Pulse Beat Audio
If MSpO
2
is selected as the MHR/P source, each pulse beat is indicated with a
“beep”: the pitch of the beep will vary according to the saturation value; the pitch
rises as the saturation value increases; the pitch lowers as the saturation value
decreases. If MECG is selected as the MHR/P source, the MECG audio plink is used
instead; it will not vary in pitch. NIBP cannot be chosen as the MHR/P source.
(Refer to Chapter 7, “Maternal Heart/Pulse Rate Monitoring” for more information.)
The MSpO
2
Waveform
When MSpO
2
monitoring is employed, the MSpO
2
pulsatile (plethysmograph)
waveform can be displayed and printed. Refer to Chapter 14, “Waveforms” for more
information.
When enabled, the MSpO
2
trend prints in the bottom grid as a grey trace annotated
by MSpO
2
. Values are printed on the annotation area preceded by an outlined
diamond which marks the time of the reading.
Module and Probe Compatibility
Ohmeda, Masimo, and Nellcor pulse oximetry parameters are calibrated to display
functional saturation. Other manufacturer’s pulse oximetry monitors may be
calibrated to display fractional saturation.
250cx Series Monitors with Masimo Technology are compatible only with
Masimo LNOP and LNCS sensors. For additional information, refer to
Directions for Use supplied with sensor.
250cx Series Monitors with Ohmeda Technology are compatible only with
Ohmeda OxiTip+ sensors. For additional information, refer to Directions for
Use supplied with sensor.
250cx Series Monitors with Nellcor Technology are compatible only
with Nellcor OxiMax sensors. For additional information, refer to
Directions for Use supplied with sensor.
IMPORTANT: Use only Masimo LNOP oximetry sensors with the Masimo
Technology, Ohmeda sensors with the Ohmeda Technology, and Nellcor
sensors with the Nellcor Technology. Other sensors may result in unpredictable
performance.
The MSpO
2
cable should plug into the monitor’s MSpO
2
connector easily and
securely. Do not use excessive force to connect the cable. If the MSpO
2
cable does
not easily fit into the MSpO
2
connector on the monitor, it is likely that you are using
an incorrect cable.
IMPORTANT: It is possible to connect the wrong MSpO
2
cable and/or
sensor to the monitor. If this happens, the MSpO
2
parameter will not work
(Ohmeda and Masimo) or will cause an error (Nellcor error: SENSOR). Be sure
to check the type of MSpO
2
technology your monitor contains (the label next to
the lower, right-hand side of the display) and use the corresponding cables and
sensors for that technology.
