Selecting a Sensor
Sensors are designed for specific sites on patients with designated weight ranges. To select
the appropriate sensor, consider the patient’s weight, level of activity, adequacy of perfusion,
which sensor sites are available, whether sterility is required, and the anticipated duration of
monitoring.
Cleaning and Re-use
Do not immerse any OXISENSOR™, DURASENSOR®, OXIBAND®, or DURAFORM™
oxygen transducer, the Nellcor® RS-10 oxygen transducer, or any Nellcor® adhesive in
water or cleaning solution. Clean DURASENSOR®, OXIBAND®, and DURAFORM™ oxygen
transducers, and the Nellcor® RS-10 oxygen transducer by wiping with a disinfectant such
as 70% alcohol. Do not sterilize by irradiation, steam, or ethylene oxide. Use a new
OXIBAND® adhesive wrap or FORM-A adhesive bandage for each patient. Do not re-
sterilize OXISENSOR™ oxygen transducers.
Performance Considerations
To insure 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.
If poor perfusion affects instrument performance, and the patient weighs more than 50 kg
(110 lbs.), consider using the OXISENSOR™ R-15 adult nasal oxygen transducer. Because
the R-15 obtains its measurements from the nasal septal anterior ethmoid artery, an artery
supplied by the internal carotid, this sensor may obtain measurements when peripheral
perfusion is relatively poor. For low peripheral perfusion, consider using the Nellcor® RS-10
reflectance oxygen transducer, which is applied to the forehead or temple.
If patient movement presents a problem:
• Verify that the sensor is properly and securely applied.
• Use a new sensor with fresh adhesive backing.
• Move the sensor to a less active site.
• Use a type of sensor that tolerates some patient motion, such as the OXISENSOR™ D-25,
D-20, N-25, or I20 oxygen transducer.
