Masimo settings
When the monitor has a Masimo module installed, the following settings are additionally
available:
Note
The extra settings for masimo modules are only available when Masimo settings
enabled in the parameter settings (see
Parameter
Description
Display Signal IQ (SIQ)
Waveform
1
1.
It is necessary to reboot the device after changing this setting.
On
, Off. This value shows the acquired signal quality and timing of
the pulse relative to the plethysmograph. A vertical line is displayed
corresponding with the pulse beep: a tall vertical line indicates a
high quality signal, a small line indicates a low quality signal.
Display Perfusion Index (PI)
2
2.
It is necessary to reboot the device after changing this setting.
On
, Off. The perfusion index indicates the percentage of pulsatile to
non-pulsatile signal. The range of signal strength is 0.02 to 20%. A
value of 0 indicates that no measurement is available. This setting
allows clinicians to place sensors on optimal sites and can also be
used as a troubleshooting tool.
Averaging Time
2, 4, 8, 10, 12, 14, 16. Averaging time in seconds. It is recommended
that the default of 8 seconds is suitable for most applications.
Sensitivity
Normal
, Max, APOD. The normal mode provides the best
combination of sensitivity and probe off detection performance. This
mode is recommended for the majority of patients.
The max mode can be used where obtaining a reading is most
difficult and the signal may be very weak.
The adaptive probe off detection (APOD) mode is the least
sensitive in picking up a reading on patients with low perfusion but
has the best detection for off-probe conditions. This mode can be
used for patients that are at particular risk of the sensor becoming
detached (pediatric, combative, etc).
Fast SAT
Off
, on. Fast SAT mode enables rapid tracking of arterial oxygen
saturation changes by minimizing the averaging. This mode is
clinically applicable during procedures when detecting rapid
changes in oxygen saturation is paramount such as induction,
intubation and sleep studies.
Fast SAT is always on when averaging time (above) is set to 2 or 4.
