Monitoring 8-3
WarningWarning
Interference leading to inaccurate measurements can be caused by:
- High levels of ambient light (Hint: cover application site with opaque
material)
- Electromagnetic interference
- Excessive patient movement and vibration.
WarningWarning
This equipment is not suitable for use in the presence of a flammable
anesthetic mixture or oxygen concentrations greater than 25% (or partial
pressures greater than 27,5 kPa /206.27 mmHg).

Information
for the User
The pulse oximeter is calibrated to indicate functional oxygen saturation
(fractional oxyhemoglobin), and displayed results can range from 0 to 100%.
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.
Physiological SpO
2
alarm signals will be generated at the Information Center.
The SpO
2
low limit can be set between 50 and 99% inclusive, in 1%
increments. The SpO
2
high alarm limit can be set between 51 and 100%
inclusive, in 1% increments. The maximum delay between the physiological
alarm condition and alarm signal generation at the central station is 10 seconds.
Pulse rate is also derived from the pulsatile SpO
2
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.
