To ensure safety, avoid stacking multiple devices or placing anything on the device during operation.
To protect against injury, follow the directions below:
Avoid placing the device on surfaces with visible liquid spills.
Do not soak or immerse the device in liquids.
Do not attempt to sterilize the device.
Use cleaning solutions only as instructed in this operator's manual.
Do not attempt to clean the device while monitoring a patient.
To protect from electric shock always remove the sensor and completely disconnect the pulse oximeter
before bathing the patient.
If any measurement seems questionable, first check the patient’s vital signs by alternate means and then
check the pulse oximeter for proper functioning.
Inaccurate SpO

readings may be caused by:
Improper sensor application and placement.
Elevated levels of COHb or MetHb: High levels of COHb or MetHb may occur with a seemingly normal
SpO

. When elevated levels of COHb or MetHb are suspected, laboratory analysis (CO-Oximetry) of
a blood sample should be performed.
Elevated levels of bilirubin.
Elevated levels of dyshemoglobin.
Vasospastic disease, such as Raynaud’s, and peripheral vascular disease.
Hemoglobinopathies and synthesis disorders such as thalassemias, Hb s, Hb c, sickle cell, etc.
Hypocapnic or hypercapnic conditions.
Severe anemia.
Very low arterial perfusion.
Extreme motion artifact.
Abnormal venous pulsation or venous constriction.
Severe vasoconstriction or hypothermia.
Arterial catheters and intra-aortic balloon.
Intravascular dyes, such as indocyanine green or methylene blue.
Externally applied coloring and texture, such as nail polish, acrylic nails, glitter, etc.
Birthmark(s), tattoos, skin discolorations, moisture on skin, deformed or abnormal fingers. etc.
Skin color disorders.
Interfering Substances: Dyes or any substance containing dyes that change usual blood pigmentation may
cause erroneous readings.
The pulse oximeter should not be used as the sole basis for medical decisions. It must be used in
conjunction with clinical signs and symptoms.
The pulse oximeter is not an apnea monitor.
The pulse oximeter may be used during defibrillation, but this may affect the accuracy or availability of
the parameters and measurements.
The pulse oximeter may be used during electrocautery, but this may affect the accuracy or availability of
the parameters and measurements.
The pulse oximeter should not be used for arrhythmia analysis.
SpO

is empirically calibrated in healthy adult volunteers with normal levels of carboxyhemoglobin
(COHb) and methemoglobin (MetHb).
Do not adjust, repair, open, disassemble, or modify the pulse oximeter or accessories. Injury to personnel
or equipment damage could occur. Return the pulse oximeter for servicing if necessary.
During a technical alarm condition, the SpO
