User & Service Manual
Xltek® Trex HD Amplifier
21
Inspection of monitors, cables, and probes should be completed prior to each use to ensure
compatibility and maintain patient safety.
The Trex HD amplifier system does NOT include SpO
2
or Pulse Rate alarms.
3.6. 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.
Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or
intravascular line may cause inaccurate measurements.
Loss of pulse signal can occur when the sensor is too tight.
Do not use damaged pulse oximetry sensors. Do not use sensors with exposed optical
components. Do not immerse the sensor in water, solvents or cleaning solutions (the
sensors and connectors are not waterproof). Do not sterilize by irradiation, steam, or
ethylene oxide. See the cleaning instructions in the directions for use for the reusable pulse
oximetry sensors.
Do not use damaged patient cables. Do not immerse the patient cables in water, solvents,
or cleaning solutions (the patient cable connectors are not waterproof). Do not sterilize by
irradiation, steam, or ethylene oxide. See the cleaning instructions in the directions for use
for reusable patient cables.
The oximeter sensor may not work on cold extremities due to reduced circulation. Warm or
rub the finger to increase circulation, or reposition the sensor.
