Fast SAT When Fast
SAT
is enabled and there is
1
data point that is
significantly different from a previous data point, averaging is
disregarded and most recent data point is displayed. For example, if
readings were
97%
,
96%
,
95%
and
85%
, displayed saturation level
would be
85%
.
PI Perfusion Index (
PI
) is a scaled numeric value derived from
magnitude of pulsations displayed on plethysmographic (pleth)
waveform. It is calculated as a percentage of pulsatile signal to
nonpulsatile signal.
PI
is used to find best perfused site for sensor
placement (larger the
PI
, stronger the perfusion). Operating range is
0.02
to
20
. Desired number is greater than
1
or as large as possible.
Saturation Averaging Time Averaging time can be set to
2
,
4
,
8
,
10
,
12
,
14
or
16
seconds.
Sensitivity Mode Sensitivity mode, normal or maximum, of current monitoring
configuration is displayed in options mode. Normal setting is used for
normal patient monitoring purposes. Maximum setting is used for
improved low perfusion performance.
SET
®
Technology Signal Extraction Technology
®
(
SET ®
) uses adaptive filters to separate
arterial signal from nonarterial noise.
SET ®
provides for accurate
readings under extreme conditions; such as, low perfusion and
motion.
