If patient movement presents a problem:
e Verify that the sensor is properly and securely applied.
e Use a new sensor with fresh adhesive backing.
e Move the sensor to a less active site.
e Use a type of sensor that tolerates some patient motion, such as the OXISENSORTM
D-25, D-20, N-25, or 120 oxygen transducer.

D. Automatic Calibration of NELLCOR® Sensors
The oximetry subsystem incorporates automatic calibration mechanisms. It is
automatically calibrated each time it is turned on, at periodic intervals thereafter, and
whenever a new sensor is connected. Also, the intensity of the sensor's LEDs is
adjusted automatically to compensate for differences in tissue thickness.
Each sensor is calibrated when manufactured; the effective mean wavelength of the red
LED is determined and encoded into a calibration resistor in the sensor plug. The
instrument's software reads this calibration resistor to determine the appropriate
calibration coefficients for the measurements obtained by that sensor.
