Real-Time Trend Display
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.
SpO2 and Pulse Rates
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
2
and pulse rate on a patient. These
individual matrices or combinations of these matrices are used to
drive the LED indicators on the N
- 600x front panel.
