Notes:
• Do not shake your finger during the test. It is
recommended that you stay still and do not move
while taking a reading.
• The height of the pulse bar is an indication of the
pulse and signal strength. The bar should be greater
than 30% for a proper reading.
• The device must be able to measure the pulse proper-
ly to obtain an accurate SpO
2
measurement. Verify
that nothing is hindering the pulse measurement
before relying on the SpO
2
measurement.
• Do not use the device on a single location for more
than 30 minutes in order to ensure correct sensor
alignment and skin integrity.
Inaccurate measurements may occur if:
• The patient suffers from significant levels of dysfunc-
tional hemoglobin (such as carboxyhemoglobin or
methemoglobin).
• Intravascular dyes such as indocyanine green or
methylene blue have been injected into the patient.
• Used in the presence of high ambient light (e.g. direct
sunlight). Shield the sensor area with a surgical towel
if necessary.
• There is excessive patient movement.
• The patient experiences venous pulsations.
• The patient has hypotension, severe
vasoconstriction,severe anemia, or hypothermia.
• The patient is in cardiac arrest or is in shock.
• Fingernail polish or false fingernails are applied.
3.3. Low oxygen saturation & pulse alert
A warning alert will sound if the device detects:
• Your pulse rate is lower than 50 bpm
• Your pulse rate higher than 130 bpm
• If the SpO
2
level is lower than 94%
