• Verify if the sensor is properly positioned by observing at least ten seconds of a continuous
plethysmogram waveform being displayed.
• If the Bar-graph Pulse Level is at a low level,
“weak pulse”
message will be displayed.
Reposition the sensor or try a different sensor.
• The LifeWindow™ Lite LW8 audible “beep” is by default generated by the ECG detection,
modulated in tone by the SpO2 value. The source of the “beep” can be changed to SpO2
pulse detection. To change the “beep” source, touch the System menu and touch Sound
Volume menu. Select the Beep Source to SpO2.
NOTE:
Reusable sensors may be used on the same site for a maximum of four (4) hours, provided the
site is inspected routinely to ensure skin integrity and correct positioning. Because individual
skin condition affects the ability of the skin to tolerate sensor placement, it may be necessary to
change the sensor site more frequently with some patients.
Loss of pulse can occur if:
• The sensor is to tight.
• There is excessive illumination (e.g., a surgical or bilirubin lamp or direct sunlight).
• The sensor is placed on an extremity with a blood pressure cuff, arterial catheter or
intravascular line.
• The patient experiences shock, hypertension, severe vasoconstriction, severe anemia,
hypothermia, arterial occlusion to the sensor, or cardiac arrest.
Inaccurate measurements may be caused by:
• Incorrect application of dysfunctional hemoglobin’s, such as carboxyhemoglobin or
methemoglobin.
• Significant, levels of indocyanine green, ethylene blue or other intravascular dyes.
• Exposure to excessive illumination, such as surgical lamps, especially ones with a xenon light
source; bilirubin lamps, fluorescent lights; infrared heating lamps; or direct sunlight.
• Excessive patient movement.
• Venous pulsation’s.
• Electrosurgical interference.
• Placement of the sensor on an extremity that has a blood pressure cuff, arterial catheter or
intravascular line.
Do not attach a probe to the same limb with a blood pressure cuff. The data received will not be
valid when the cuff is inflated. Attach the probe to the limb opposite the site used for the blood
pressure cuff.
