Technical Difficulties Experienced with CGMS System in ICU

Problem identified Possible etiologies
Sensor failure Improper connection between transmitter and sensor
Inadequate time for “wetting” of sensor
Sensor accuracy Improper calibration protocols
Unstable patient glucose levels
Signal interference Electronic product interference using same frequency band
