SpO2 and Pulse Rates

N-600x Operator's Manual
The real-time trend display includes %SpO2 and/or pulse rate
trend data plots and current measured %SpO2 and pulse rates.
The trend data plots are automatically updated as each new trend
point is calculated, where the interval between calculations is
based on the display time scale selected. If SatSeconds is enabled,
the real-time trend display includes the SatSeconds indicator.
Decimal points after the displayed %SpO2 or pulse rate indicate
that the respective limits have been changed from the power-on
defaults. Each time a pulse is detected by the oximeter, a heart
icon flashes.
There are various matrixes within the N-600x algorithm. Some of
these are used to assess the severity of conditions presented to
the N-600x in measuring SpO
individual matrices or combinations of these matrices are used to
drive the LED indicators on the N-600x front panel.
The N-600x algorithm automatically extends the amount of data
required for measuring SpO
measurement conditions. During normal measurement conditions
the averaging time is 6 to 7 seconds. During conditions such as
those caused by low perfusion, interference (e.g., external
interference such as ambient light or patient movement), or a
combination of these, the N-600x algorithm automatically
extends the amount of data required beyond 7 seconds. If the
resulting dynamic averaging time exceeds 20 seconds, the pulse
