SpO2 Safety Information
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
Note — The averaging filter time period is configurable at the IntelliVue
Information Center iX (default = 10 seconds).
alarm signals will be generated. For adult patients, the
low limit can be set between 50 and 99% inclusive, in 1% increments,
and the SpO
high alarm limit can be set between 51 and 100% inclusive, in
1% increments. For pediatric patients, the SpO
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
Pulse rate is also derived from the pulsatile SpO
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.
