Sensor Compatibility Compatible only with Nellcor sensors listed in the Micropaq monitor section
of the Welch Allyn Products and Accessories booklet (810-0409-XX).
For probe/sensor compliance to EN ISO 9919:2005, see the Nellcor directions
for use.
Sensor LED Wavelengths Within 500 to 1,000 nm
Sensor Energies (Radiant Power) Does not exceed 15 mW
WARNING Interfering Substances: Carboxyhemoglobin may erroneously
increase readings. The level of increase is approximately equal to the amount of
carboxyhemoglobin present. Dyes, or any substances containing dyes, that
change usual arterial pigmentation may cause erroneous readings.
WARNING Although the SpO
2
alarm limit range can be adjusted down to 50%
saturation (with Acuity 6.0 software or higher), the SpO
2
performance and
accuracy is not specified below 70%.
