WARNING!
A pulse oximeter should not be used as an apnea monitor.
WARNING!
A pulse oximeter should be considered an early warning device. As a trend towards patient
deoxygenation is indicated, blood samples should be analyzed by a laboratory co-oximeter to completely
understand the patient’s condition.
WARNING!
MEASUREMENTS
If the accuracy of any measurement does not seem reasonable, first check the patient’s vital signs by
alternate means and then check the pulse oximeter for proper functioning.
Inaccurate measurements may be caused by:
•
Incorrect sensor application or use
•
Significant levels of dysfunctional hemoglobin (e.g., carboxyhemoglobin or methemoglobin)
•
Intravascular dyes such as indocyanine green or 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 (exposure to excessive
illumination can be corrected by covering the sensor with a dark or opaque material)
•
Excessive patient movement
•
Venous pulsations
•
Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular
line
•
The pulse oximeter can be used during defibrillation, but the readings may be inaccurate for a short
time.
WARNING!
Interfering Substances:
Carboxyhemoglobin may erroneously increase readings. The level of
increase is approximately equal to the amount of carboxyhemoglobin present. Dyes, or any substance
containing dyes, that change usual arterial pigmentation may cause erroneous readings.
WARNING!
ALARMS Check alarm limits each time the pulse oximeter is used to ensure that they are
appropriate for the patient being monitored.
WARNING!
Loss of pulse signal can occur in any of the following situations:
•
The sensor is too tight
•
There is excessive illumination from light sources such as a surgical lamp, a bilirubin lamp, or sunlight
•
A blood pressure cuff is inflated on the same extremity as the one with a SpO
2
sensor attached
•
The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia
•
There is arterial occlusion proximal to the sensor
•
The patient is in cardiac arrest or is in shock
WARNING!
Sensors:
•
Before use, carefully read the LNCS
®
sensor directions for use.
•
Use only Masimo oximetry sensors for SpO
2
measurements. Other oxygen transducers (sensors)
may cause improper performance.
•
Tissue damage can be caused by incorrect application or use of an LNCS
®
sensor, for example by
wrapping the sensor too tightly. Inspect the sensor site as directed in the sensor Directions for Use
to ensure skin integrity and correct positioning and adhesion of the sensor.
•
Do not damage LNCS
®
sensors. Do not use an LNCS
®
sensor with exposed optical components. Do
not immerse the sensor in water, solvents, or cleaning solutions (the sensors and connectors are not
waterproof). Do not sterilize by irradiation, steam or ethylene oxide. See the cleaning instructions
in the directions for reusable Masimo LNCS
®
sensors.
•
Do not use damaged patient cables. Do not immerse the patient cables in water, solvents or
cleaning solutions (the patient cables are not waterproof). Do not sterilize by irradiation, steam or
ethylene oxide. See the cleaning instructions in the directions for reusable Masimo patient cables.
