necessary, remove and reapply the sensor. If any of the above mentioned indications
occur, immediately remove the sensor and find an alternate site.
NOTE: Check the sensor site more frequently on neonate and active
patients.
• Incorrect placement can also reduce the acquired sensor signal, and therefore
compromise performance. Select an alternate site (toe) if the sensor can not be placed
on the patient’s finger correctly or if the fingernails interfere with the acquisition of a
reliable signal.
• Use of the reusable sensor is not recommended for long-term monitoring (4 to 6 hours).
For monitoring situations exceeding 4 to 6 hours, either reposition the reusable sensor
every 2 to 4 hours to a different site (finger/toe) or use a disposable sensor with its
appropriate bandage.
CAUTION: Prolonged and continuous monitoring may increase the risk
of skin erosion and pressure necrosis at the site of the
sensor. Check the SpO2 sensor site frequently to ensure
proper positioning, alignment, and skin integrity at least
every eight (8) hours; with the Adult and Pediatric re-usable
finger sensor, check every four (4) hours; for neonates and
patients of poor perfusion or with skin sensitive to light,
check every 2 - 3 hours; more frequent examinations may
be required for different patients. Change the sensor site if
signs of circulatory compromise occur. Ensure proper
adhesion, skin integrity, and proper alignment. Exercise
extreme caution with poorly perfused patients. When
sensors are not frequently monitored, skin erosion and
pressure necrosis can occur. Assess the site every two (2)
hours with poorly perfused patients and neonates.
• Do not over-tighten the sensor bandages. Excessive pressure on the monitoring site can
affect SpO
2
readings and may reduce readings below true SpO
2
. Excessive pressure
can also result in pressure necrosis and other skin damage.

with Nellcor
®
Pulse Oximetry
This is an optional feature.
1. Plug the sensor directly into the SpO2 Connector (20) or if necessary, use a Nellcor
®
DOC-10 extension cable.
2. See package insert(s) for use and care instructions. Additional information is available
from Nellcor Puritan Bennett Inc. at www.nellcor.com.
CAUTION: When equipped with Nellcor® SpO2, use only Nellcor®
oxygen transducers including Nellcor® Oxisensor® patient
dedicated adhesive sensors. Use of other oxygen
transducers may cause improper oximeter performance.
CAUTION: Excessive ambient light may cause inaccurate SpO2
measurements. Cover the sensor with opaque materials.
