Warning
Removal of the SpO2 sensor from the MX40 patient cable during
Continuous SpO2 monitoring results in a "No Sensor" technical alarm.
Silencing this alarm turns the SpO2 measurement off, however the SpO2
module is still operating in the background and consuming battery
power. If you do not intend to resume continuous SpO2 monitoring,
change to Manual mode.There is no technical alarm for a "No Sensor"
condition in Manual mode.
If you measure SpO2 on a limb that has an inflated NBP cuff, a
non-pulsatile SpO2 technical alarm can occur. If the monitor is
configured to suppress this alarm, there can be a delay of up to 60
seconds in indicating critical patient status, such as sudden pulse loss or
hypoxia.
SpO2 measurements can be made manually on an as-needed basis in
Manual mode, or continuously in Continuous mode, depending on your
MX40 configuration. While operating in Continuous mode, you can also
measure pulse, and display the pleth wave on the MX40 and at the
Information Center. The SpO2 parameter is turned on/off at the MX40 or by
a control from the Information Center. SpO2 monitoring consumes
considerable electrical energy. The battery power must be at least 10% full
in order to make SpO2 measurements.
To resume the SpO2 measurement after it has been turned off, touch the
blank measurement area and select SpO
2
to turn it back on.
Note — Before disabling SpO2 at the Information Center, acknowledge any
active alarms at the MX40.
Setting the mode to Manual or Continuous can be done at the Information
Center or at the MX40.
