Cautions
Introduction
CAUTION:
Inaccurate reading may be caused by incorrect sensor
application or use; significant levels of dysfunctional
hemoglobins, (i.e. carbohemoglobins or methemoglobin); or
intra-vascular dyes such as indocyanine green methylene
blue; exposure to excessive illumination, such as surgical
lamps (especially ones with a Xenon light source), bilirubin
lamps, fluorescent lights, infrared heating lamps, or direct
sunlight; excessive patient movement; venous pulsations;
electro-surgical interference; and placement of a sensor on
an extremity that has a blood pressure cuff, arterial
catheter, or intra-vascular line.
CAUTION:
In certain situations in which perfusion and signal strength
are low, such as in patients with thick or pigmented skin,
inaccurately low SpO
2
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:
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.
CAUTION:
When equipped with MASIMO
®
SpO
2
, use only MASIMO
®
oxygen transducers including MASIMO LNOP
®
patient
dedicated adhesive sensors and MASIMO PC Series Patient
Cable. Use of other oxygen transducers may cause
improper Oximetry performance.
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 SpO2 sensor site should be checked at least every eight
(8) hours (every two (2) hours with the Adult re-usable
finger sensor). Ensure proper adhesion, skin integrity, and
proper alignment. 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 and neonates.
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.
CAUTION:
Use only authorized probe covers. Use of any other probe
cover may result in erroneous readings or damage to the
probe.
CAUTION:
Changing any part of the time or date will cause all stored
patient information (trend data) to be permanently erased.
Viewing the time or date does NOT cause data to be erased.
CAUTION:
To avoid loss of patient data (trend), do not replace the
battery unless the Accutorr Plus is connected to an AC
receptacle. Hospital defaults and the time are unaffected by
battery replacement.
