CAUTIONS OF USE
• Fingers that
are too thin or too cold may affect the measurement result and cause the SpO2 and
pulse rate readings to be incorrect. In this case, insert a thick finger, such as a thumb or middle
finger, deep enough into the probe.
• D
o not use the device on infants or neonates.
• The
product is suitable for children over four years of age and adults (the weight should be
between 15 kg and 110 kg).
• The examined person must not have
painted nails.
• The subject's nails must not be too
long.
• If stable readings cannot b
e obtained, stop measuring. The device may not work properly for all
patients.
• If the screen displays abnormal indications during the test, pull your finger out and
reinsert it to
restore normal operation.
• Read the me
asured value when the pulse waveform is normalized and the pulse waveform on the
screen is even and stable.
• Contact your doctor if the device is working properly and the indications are outside the no
rm.
Clinical limitations
• Factors that may cause inac
curate measurements:
o Poor heart rate
Significant pulsating blood flow is required for correct measurement. If you have a poor pulse due to
shock, low ambient / body temperature, heavy bleeding, or use of a vasoconstrictor drug, your SpO2
value will decrease.
o Anemia, low hemoglobin, toxic hypoxia.
If you have severe anemia, the device may show abnormal SpO2 measurements.
