Trex™ HD Monitoring Amplifier
21
Do not immerse the sensor in water, solvents, or cleaning solutions. Do not sterilize the
sensor by irradiation, steam or ethylene oxide.
Do not immerse patient cables in water, solvents, or cleaning solutions (the patient cable
connectors are not waterproof). Do not sterilize patient cables by irradiation, steam or
ethylene oxide.
As with all medical equipment, carefully route cables and connections to minimize the
possibility of entanglement or strangulation.
Operation of this module below the minimum amplitude of 0.3% modulation may cause
inaccurate results.
Oximeter readings may be affected by the use of an electrosurgical unit (ESU).
Inspection of monitors, cables, and probes should be completed prior to each use to ensure
compatibility and maintain patient safety.
The Trex HD Monitoring amplifier system does NOT include SpO
2
or Pulse Rate alarms.
3.7. Pulse Oximeter Sensor Warnings
Before using, carefully read the sensor directions for use.
Use only Nonin oximetry sensors, as required, for SpO2 measurements. These sensors are
manufactured to meet the accuracy specifications for the pulse oximeter. Other oxygen
transducers (sensors) may cause improper pulse oximeter performance.
Tissue damage can be caused by incorrect application or use of a pulse oximetry sensor
(i.e. by wrapping the sensor too tightly). Inspect the sensor site as directed in the sensor
directions for use to ensure skin integrity and correct positioning and adhesion of the
sensor.
Patient sensitivity may vary due to medical status or skin condition. Discontinue use of
adhesive tape strips if the patient exhibits an allergic reaction to the adhesive material.
Do not use pulse oximetry sensors during MRI scanning as this could potentially cause
burns. The pulse oximeter may affect the MRI image, and the MRI unit may affect the
accuracy of the oximetry measurements.
