UT100 Handheld Pulse Oximeter Operation Manual 1-3
WARNING! In the event that earth ground integrity is lost, the
performance of this device and/or other devices nearby may
be affected due to excessive RF emissions.
WARNING! Any monitor that has been dropped or damaged should be
inspected by qualified service personnel, prior to use, to insure
proper operation.
WARNING! If the accuracy of any measurement is in question, verify the
patient’s vital sign(s) by an alternative method and then check
the monitor for proper functioning.
WARNING! Remove device batteries prior to long term storage.
WARNING! Operation of this device may be adversely affected in the
presence of strong electromagnetic sources, such as
electrosurgery equipment.
WARNING! Operation of this device may be adversely affected in the
presence of computed tomograph (CT) equipment.
WARNING! Use only SpO
2
sensors supplied with, or specifically intended
for use with, this device.
WARNING! SpO
2
measurements may be adversely affected in the presence
of high ambient light. Shield the sensor area (with a surgical
towel, for example) if necessary.
WARNING! Dyes introduced into the bloodstream, such as methylene blue,
indocyanine green, indigo carmine, patent blue V (PBV), and
fluorescein may adversely affect the accuracy of the SpO
2
reading.
WARNING! Any condition that restricts blood flow, such as use of a blood
pressure cuff or extremes in systemic vascular resistance, may
cause an inability to determine accurate pulse rate and SpO
2
readings.
WARNING! Significant levels of dysfunctional hemoglobins, such as
carboxyhemoglobin or methemoglobin, will affect the accuracy
of the SpO
2
measurement.
