●Applying the LNCS DCI, RD SET DCI
1. Open the sensor by pressing on hinge tabs. Place the selected digit over
the sensor window of the LNCS DCI or DCIP. The fleshiest part of the
digit should be covering the detector window in the lower half of the
sensor. The top half of the sensor is identified by the cable. On finger
sites, the tip of the finger should touch the raised digit stop inside the
sensor. If the fingernail is long, it may extend over and pass the finger
stop (Fig. 1).
2. The hinged tabs of the sensor should open to evenly distribute the grip of
the sensor along the length of the finger. Check position of sensor to
verify correct positioning. Complete coverage of the detector window is
needed to ensure accurate data (Fig. 2).
3. Orient the sensor so that the cable will be running towards the top of the
patient’s hand (as shown in Fig. 3). Connect the sensor connector to a
patient cable.

Precautions for Using the LNCS DCI, RD SET DCI
CAUTION
 Do not sterilize by irradiation, steam autoclave or ethylene oxide.
 Before using the sensor, ensure that the sensor is physically intact, with no
broken or frayed wires or damaged parts.
 Do not immerse the sensor or connector in any liquid solution.
 With smaller digits, in order to completely cover the detector window, the digit
might not need to be pushed all the way to the stop. The sensor is not intended
for use on the thumb or across a child’s hand or foot.
 The site must be checked or changed at least every four hours to ensure
adequate adhesion, circulation, skin integrity and correct optical alignment.
 Exercise extreme caution with poorly perfused patients; skin erosion and
pressure necrosis can be caused when the sensor is not frequently moved.
Assess site at least every two (2) hours with poorly perfused patients.
 During low perfusion, the sensor site needs to be assessed frequently for signs
of tissue ischemia, which can lead to pressure necrosis.
 With very low perfusion at the monitored site, the readings may read lower
than core arterial oxygen saturation.
 Sensors applied too tightly may cause erroneously low readings.
 Circulation distal to the sensor site should be checked routinely.
 Misapplied sensors or sensors that become partially dislodged may cause
either over or under reading of actual arterial oxygen saturation.
