CAUTION: In certain situations in which perfusion and signal strength are low, such as in
patients with thick or pigmented skin, inaccurately low SpO2 readings will result.
Verification of oxygenation should be made, especially in preterm infants and patients
with chronic lung disease, before instituting any therapy or intervention.
CAUTION: Many patients suffer from poor peripheral perfusion due to hypothermia, hypovolemia,
severe vasoconstriction, reduced cardiac output, etc. These symptoms may cause a loss in
vital sign readings.
CAUTION: The site should be checked at least every eight (8) hours (every four (4) hours with
the Adult re-usable finger sensor). Ensure proper adhesion, skin integrity, and proper
alignment. Nail polish and fungus may effect readings. Exercise extreme caution with
poorly perfused patients. Skin erosion and pressure necrosis can be caused when sensors
are not frequently monitored. Assess the site every two (2) hours with poorly perfused
patients.
CAUTION: If the sensor or patient cable is damaged in any way, discontinue use immediately. To
prevent damage do not soak or immerse the sensor in any liquid solution. Do not attempt
to sterilize.
3. The digital SpO2 value and SpO2 Pulse Rate will be displayed on the SpOz and Pulse
Rate LED's.
4. If desired, adjust the beep volume. See Section 3.7, "Setting the Alarm Volume and
Beep Volume", for details on adjusting the beep volume.
1.3.10.3.1 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 indicated for continuous non invasive monitoring of arterial oxygen
saturation (SpO2) and pulse rate. The LNOP® - DC1 Adult Re-usable Finger Sensor can
also be used for "spot check" applications if needed. All sensors are intended for "single-
patient use only" except for the LNOP® - DC1 Adult "Re-usable" Finger Sensor.
A. 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 and the anticipated duration of monitoring.
B. Cleaning and Re-use
The sensor may be reattached to the same patient if the emitter and detector windows are
clear and the adhesive still adheres to the skin. The adhesive can be partially rejuvenated
by wiping with an alcohol wipe and allowing the sensor to thoroughly air dry prior to
replacement on the patient.
