SpO2 Safety Information
9-4 SpO2 Monitoring
A 10 second averaging filter is used in the calculation of the result.
Displayed results are typically updated every second, but the update
period can be automatically delayed by up to 30 seconds in the presence of
noise.
Note — The averaging filter time period is configurable at the IntelliVue
Information Center iX (default = 10 seconds).
Physiological SpO2 alarm signals will be generated. For adult patients, the
SpO2 low limit can be set between 50 and 99% inclusive, in 1% increments,
and the SpO2 high alarm limit can be set between 51 and 100% inclusive, in
1% increments. For pediatric patients, the SpO2 low limit can be set between
30 and 99% inclusive, in 1% increments, and the high alarm limit can be set
between 31 and 100% inclusive, in 1% increments. The maximum delay
between the physiological alarm condition and alarm signal generation is
25 seconds.
Pulse rate is also derived from the pulsatile SpO2 measurement, and
displayed results can range from 30 to 300 bpm. There is no alarm function
for pulse rate.
The pleth wave is auto-scaled to maximum display size. It decreases only
when the signal quality becomes marginal. Pleth wave size is NOT directly
proportional to the pulse volume.
