2. If the fingernail is long, the nail tip will extend over the finger stop. (2)
3. Spread open the rear tabs of the sensor to provide even force over the length of the pads.
Check the position of the sensor. If an index finger cannot be positioned correctly, or is not
available, a smaller finger can be used, or use an OxiMax™ or an Oxisensor II oxygen sensor.
Do not use the DS100A on a thumb or toe or across a child's hand or foot. (3)
Note: When selecting a sensor site, priority should be given to an extremity free of an arterial
catheter, blood pressure cuff, or intravascular infusion line.
4. The sensor should be oriented in such a way that the cable is positioned along the top of the
hand. (4)
5. Plug the DS100A into the oximeter and verify proper operation as described in the oximeter
operator's manual.
Note: If the sensor does not track the pulse reliably, it may be incorrectly positioned—or the
sensor site may be too thick, thin, or deeply pigmented, or otherwise deeply colored (for
example, as a result of externally applied coloring such as nail polish, dye, or pigmented
cream) to permit appropriate light transmission. If any of these situations occurs,
reposition the sensor or choose an alternate Nellcor sensor for use on a different site.
Cleaning
The DS100A may be surface-cleaned by wiping it with a solution such as 70% isopropyl alcohol.
If low-level disinfection is required, use a 1:10 bleach solution. Do not use undiluted bleach
(5%~5.25% sodium hypochlorite) or any cleaning solution other than those recommended here
because permanent damage to the sensor could occur.
WARNINGS
1. If the sensor is misapplied with excessive pressure for prolonged periods, a pressure injury
can occur.
CAUTION: Do not expose connector pins to cleaning solution as this may damage the sensor.
To clean or disinfect the sensor:
1. Saturate a clean, dry gauze pad with the cleaning solution. Wipe all surfaces of the sensor
and cable with this gauze pad.
2. Saturate another clean, dry gauze pad with sterile or distilled water. Wipe all surfaces of the
sensor and cable with this gauze pad.
3. Dry the sensor and cable by wiping all surfaces with a clean, dry gauze pad.
CAUTIONS
1. Do not sterilize by irradiation, steam, or ethylene oxide. Such sterilization could damage the
sensor.
