MENU ITEMS DESCRIPTION
VIEW
Three views are available: Pleth and Signal IQ, Numbers and Pleth
Only.
PLETH + SIGNAL IQ
Shows the SpO
2
and pulse rate numbers on the left or top of the
screen. The plethysmograph and Signal IQ waveform on the right,
two-thirds or bottom of the screen. The screen also indicates the signal
strength of the measured signal as a perfusion index (PI). The PI is
calculated as the relation of arterial pulsatile signal to the non-pulsatile
signal component.The percentage measurements of methemoglobin
(SpMet) and carboxyhemoglobin (SpCO) are displayed in the middle
upper third of the screen above the PI measurement.
PLETH ONLY
Shows the SpO
2
and pulse rate numbers on the left or top of the
screen. The plethysmograph waveform on the right, two-thirds or
bottom of the screen. The screen also indicates the signal strength of
the measured signal as a perfusion index (PI). The PI is calculated as
the relation of arterial pulsatile signal to the non-pulsatile signal compo-
nent.The percentage measurements of methemoglobin (SpMet) and
carboxyhemoglobin (SpCO) are displayed in the middle upper third of
the screen above the PI measurement.
NUMBERS
Shows the SpO
2
and pulse rate numbers and the signal IQ in the form
of a pulse bar on the screen. The Screen also indicates the signal
strength of the measured signal as a perfusion index (PI). The PI is
calculated as the relation of arterial pulsatile signal to the non-pulsatile
signal component. The percentage measurements of methemoglobin
(SpMet) and carboxyhemoglobin (SpCO) are displayed in the middle
of the screen in line with the PI measurement.
TREND
This allows the user to select and view the Trend data between:
■ SpO
2
and pulse rate (%SpO
2
+ BPM)
■ SpO
2
and perfusion index (%SpO
2
+ PI)
■ SpO
2
and methemoglobin (%SpO
2
+ MET)
■ SpO
2
and carboxyhemoglobin (%SpO
2
+ CO)
■ Pulse rate and perfusion index (BPM + PI)
■ Pulse rate and methemoglobin (BPM + MET)
■ Pulse rate and carboxyhemoglobin (BPM + CO)
■ Perfusion index and methemoglobin (PI + MET)
■ Perfusion index and carboxyhemoglobin (PI + CO)
■ Methemoglobin and carboxyhemoglobin (MET + CO)
■ %SpO
2
■ Pulse Rate (BPM)
■ Perfusion Index (PI)
■ Methemoglobin (MET)
■ Carboxyhemoglobin (CO)
Note: These parameters are viewed when utilizing the Trend Display
function and not the Trend Graph function.

LIMIT
Allows the user to set a custom default minimum low SpO
2
limit (1%-
99%).
The unit will return to this setting after a power cycle.
SAVE LAST
This allows the user to either use Custom setting or Adult/Neonatal
settings. Select “Yes” to use custom settings.
SAVE AS ADULT
Store current settings as Adult default setting.
SAVE AS NEO
Store current settings as Neonatal default setting.
RESTORE FACTORY
Recall factory setting for Custom, Adult and Neonatal.
VERTICAL LAYOUT
DEFAULT
Displays the alarm parameters in vertical sequence of SpO
2
, SpMet,
SpCO, BPM and PI.
TRADITIONAL
Displays the alarm parameters in vertical sequence of SpO2, BPM, PI,
SpMet and SpCO.
