Sensors
Adhesive sensors are sterile and for single use only. Reusable sensors should be
cleaned before reuse with a 70% alcohol solution. If low-level disinfection is
required, use a 1:10 bleach solution. Do not use undiluted bleach (5% - 5.25%
sodium chlorite) or any cleaning solution other than those recommended here
because permanent damage to the sensor could occur. Do not sterilize the sensor by
irradiation, steam, or ethylene oxide. If disposable sensors or their packaging are
damaged, they must be disposed of as advised in this appendix.
To clean or disinfect the sensor:
1. Saturate a clean, dry gauze pad with the cleaning solution. Wipe all surfaces of
the sensor and cable with this gauze pad.
2. Saturate another clean, dry gauze pad with sterile or distilled water. Wipe all
surfaces of the sensor and cable with this gauze pad.
3. Dry the sensor and cable by wiping all surfaces with a clean, dry gauze pad.

Calibration
The 250cx Series Monitor automatically calibrates the pulse oximetry parameter
upon power up, whenever a new sensor is attached, and at periodic intervals during
use. The intensity of the sensor’s LEDs are also automatically adjusted to
compensate for differences in tissue density.
NIBP Maintenance
A leak test of the NIBP parameter should be performed at least once a year or when
there is doubt about the validity of the pressure readings.
CAUTION
Refer calibration and leak testing to qualified service personnel.
Full calibration details are available in the Corometrics 250cx
Series Monitor Service Manual, available from GE Medical
Systems Information Technologies.
