If patient movement presents a problem:
·
Verify that the sensor is properly and securely applied.
·
Use a new sensor with fresh adhesive backing.
·
Move the sensor to a less active site.
·
Use a type of sensor that tolerates some patient motion, such as the OXISENSOR™
D-25, D-20, N-25, or I20 oxygen transducer.

D. Automatic Calibration of NELLCOR
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.
