PULSE OXIMETRY (OPTION)
Pulse Oximetry (SpO
2
) monitoring is one of the tools available to assist in assessing a patient’s cardiac and respiratory
systems. Pulse oximetry is a noninvasive method of continuously measuring oxygen saturation (SpO
2
) in arterial blood.
The resultant SpO
2
reading indicates the percentage of hemoglobin molecules in the arterial blood which are saturated
oxygen.
The Responder 2000 SpO
2
can be monitored in all operating modes.
A pulse oximetry sensor sends light through patient tissue to a receiver on the other side of the sensor.
When the SpO
2
sensor is connected; the waveform can be selected for display in Channel 2 of the dynamic graphic
display area.
1.
Turn the Rotary Selector Knob until the Channel 2 source wave heading is highlighted and press the Rotary Selector
Knob.
2.
Turn the Rotary Selector Knob until SpO
2
displays and press to select. The waveform changes to show the SpO
2
trace.
WARNING:
Do not rely solely on SpO
2
readings; assess the patient at all times. Inaccurate measurements can be caused
by:
•
Incorrect sensor application or use.
•
Significant levels of dysfunctional hemoglobins (such as carboxyhemoglobin or methemoglobin)
•
Injected dyes such as methylene blue, or intravascular dyshemoglobins such as methemoglobin or
carboxyhemoglobin
•
Exposure to excessive illumination such as surgical lamps (especially those with a xenon light source), bilirubin
lamps, fluorescent lights, infrared heating lamps, or direct sunlight.)
NOTE:
The SpO
2
alarms do not generate a printout.
NOTE:
The SpO
2
alarms can be cleared either by changing the Channel 2 Source to Cascade or by reconnecting
the SpO
2
sensors.
NOTE:
Use only sensors that are recommended in Section 7 of this manual.
WARNING:
No Alarm
Under certain conditions the device may not be able to identify a signal disturbance when monitoring the patient. In this
situation artifacts are capable of simulating a plausible parameter reading, so that the monitor fails to sound an alarm. In
order to ensure reliable patient monitoring the proper application of the probe and the signal quality must be checked at
regular intervals.
