Operation SpO 2 Pulse Oximetry
It is also possible to change the averaging time of the Saturation and Pulse Rate
measurements. The post average time can be changed to 6, 8, 10, 12, 14 or 16 seconds.
3.6.3 Performance Considerations
3.6.3.1 Calibration
3.6.3.2 Auto Scaling
To ensure optimal performance, use an appropriate sensor, apply it as directed, and observe
all warnings and cautions.
If excessive ambient light is present, cover the sensor site with opaque material. Failure to do
so may result in inaccurate measurements. Light sources that can affect performance include
surgical lights, especially those with a xenon light source, bilirubin lamps, fluorescent lights,
infrared heating lamps, and direct sunlight.
In the event that you are unable to get any reading, or the reading you get is inaccurate,
consider the following:
If your patient is poorly perfused, try applying the sensor to another site - such as a
different finger or toe.
Check that the sensor is properly aligned.
In electrosurgery, make sure sensor is not too close to ESU devices or cables.
Check to make sure the site area is clean/non-greasy. Clean site and sensor if needed.
Nail polish and fungus should be removed.
The oximetry sub-system incorporates automatic calibration mechanisms. No other
calibration is required.
The Pleth waveform is automatically scaled. There is no adjustment that can be made to the
Pleth waveform size.
3.6.4 Masimo ® Sensors and Patient Cable
Masimo provides a family of sensors suitable for a wide variety of clinical settings and
patients. Specific sensors have been developed for neonates, infants, children, and adults.
All sensors are:
1. indicated for continuous non invasive monitoring of arterial oxygen saturation (SpO2 )
and pulse rate
2. non-sterile
3. usable during patient movement
The LNOP ® DCSC Adult Reusable Spot Check Sensor is used for “spot check” applications.
The LNOP ® DCI Adult Re-usable Finger Sensor can also be used for “spot check”
applications if needed. All sensors are intended for “single-patient use only” unless indicated
as “reusable”.
