monitoring

Two SpO2 modules are available with the monitor - Masimo or Nellcor. The two modules
are distinguished by the connectors. The display data and waveform are similar for both
modules. The Masimo module has extra clinical settings for signal processing (see

“Masimo settings”

on page 71).

Pulse oximetry enables the continuous non-invasive monitoring of the functional
oxygen saturation of the arterial hemoglobin and the peripheral pulse rate.

The display shows the continuous progress of the numeric SpO

, plethysmographic

waveform and signal quality values.

The displayed plethysmographic waveform is proportional to the pulse volume.

The update period of the measurement readings on the display is approximately 2
seconds.

In accordance with the relevant standards, the temporary alarm silence period can be
set to a maximum of 2 minutes.

The peak wavelength and maximum optical power of the light emitted by the pulse
oximeter probes can be especially useful to clinicians e.g. performing photodynamic
therapy. They are as follows:

Range of peak wavelengths: 600 nm to 900 nm.

Maximum light power output: <15 mW.
