Pressing the Enter softkey selects the highlighted
sensitivity. Pressing the Return softkey returns the user
to the SpO
2
submenu.
Average Softkey
The M Series provides three (3) different time periods
over which SpO
2
values are averaged: 4 seconds,
8 seconds (default), and 16 seconds.
The averaging period is rarely changed from the
8 second default setting. For high risk patients with
rapidly changing SpO
2
conditions, the 4 second setting is
recommended. The 16 second setting should only be
used when the 8 second setting (default) is inadequate
due to extremely high artifact conditions.
The user can select the averaging period (4, 8, or
16 seconds) by pressing the Average softkey. When the
user presses the Average softkey, the following softkeys
appear: Average, Enter and Return.
The highlight area scrolls among the different averaging
periods of 4, 8, and 16 seconds every time the Average
softkey is pressed.
Pressing the Enter softkey selects the highlighted
averaging period. Pressing the Return softkey returns
the user to the SpO
2
submenu.
Alarms
The M Series SpO2 option provides user programmable
"out of range" alarms for both Sp O
2
and heart rate. See
“Default Settings” on page 10 for low and high alarm limit
default values and ranges.
When a patient's heart rate is being monitored using
ECG, the High Heart Rate alarm limit range is 60 to
280 bpm, with a default setting of 150 bpm. When the
heart rate is being monitored using pulse oximetry,
however, the maximum High Heart Rate alarm limit is
lowered to 235 bpm automatically if it was previously set
higher for ECG monitoring. The unit restores the original
High Heart Rate alarm limit setting when ECG
monitoring resumes.
When the Sp O
2
alarm state is set to "AUTO", the unit
automatically sets the lower alarm limit to 95% and
105% of the patient’s currently measured saturation
percentage (the maximum setting being 100%)
SpO
2
value respectively. The auto alarm limits are set only if
valid measurements are present for the vital sign.
See the M Series Operator’s Guide for details on
enabling, disabling, and suspending alarm functions on
the M Series unit.
Automated External Defibrillator (AED)
Operation
M Series AED units equipped with Pulse Oximetry
operate in a slightly different way than Manual and
Advisory models equipped with SpO
2
, as outlined below.
Semi-Automatic Operation
The SpO
2
monitoring parameters can be changed by
pressing the Param softkey as outlined in “Physiological
Monitoring” on page 5. The plethysmographic waveform
cannot be displayed in semi-automatic mode.
Although SpO
2
alarm functions are operational in
semi-automatic mode, heart rate alarm functions are
disabled. Background ECG analysis functions continue
to operate as described in the “AED” section of the
M Series Operator’s Guide.
The ALARM SUSPEND button can be used to activate,
deactivate, or audibly disable the SpO
2
alarms as
described in the M Series Operator’s Guide. The alarm
limit settings cannot, however, be changed in
semi-automatic mode; only the default alarm limits are
available. See the M Series Configuration Guide for
information on setting alarm limit defaults.
Manual Mode Operation
When the AED unit is in manual mode, the unit can
display the plethysmographic waveform as described in
“Displaying the Plethysmographic Waveform” on page 5.
Both heart rate and SpO
2
alarms are operational. The
alarm limits can be changed by pressing the Alarms
softkey. The SpO
2
monitoring parameters can be
changed by pressing the Param softkey as described in
“Physiological Monitoring” on page 5.
SpO
2
Setup
1. Inspect the M Series case and cables for damage.
2. Ensure that the sensor and cable are compatible
models before connecting it to the M Series unit (see
“Safety Considerations” on page 2).
3. Attach the sensor to the patient and connect the
sensor to the SpO
2
patient cable (see “Applying a
Reusable Sensor” on page 7 or “Applying a
Disposable Sensor” on page 8).
If using a reusable sensor, make sure it opens and
closes smoothly and check for foreign material such
as tape or cotton on the emitter and detector
windows. Remove any substances that may interfere
with the transmission of light between the sensor's
light source and detector.
