WARnInG! Under certain clinical conditions, pulse oximeters may display dashes if unable to display
Spo
2
and/or pulse rate values. Under these conditions, pulse oximeters may also display
erroneous values. These conditions include, but are not limited to: patient motion, low
perfusion, cardiac arrhythmias, high or low pulse rates or a combination of the above
conditions. Failure of the clinician to recognize the effects of these conditions on pulse
oximeter readings may result in patient injury.
WARnInG! optical cross-talk can occur when two or more sensors are placed in close proximity. It can be
eliminated by covering each site with opaque material.
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! Significant levels of dysfunctional hemoglobins, such as carboxyhemoglobin (as with Co-
poisoning) or methemoglobin (as with sulfonamide therapy), will affect the accuracy of the
Spo
2
measurement.
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 Spo
2
and pulse
rate readings.
WARnInG! Remove fingernail polish or false fingernails before applying Spo
2
sensors. Fingernail polish
or false fingernails may cause inaccurate Spo
2
readings.
WARnInG! Failure to carefully route the cable from the sensor to the monitor may allow the patient to
become entangled in the cable, possibly resulting in patient strangulation. Route the cable
in a way that will prevent the patient from becoming entangled in the cable. If necessary, use
tape to secure the cable.
CAUTIon! Unplug the sensor from the monitor before cleaning or disinfecting.
CAUTIon! Do not autoclave, ethylene oxide sterilize, or immerse the monitor and other accessories in
liquid. Evidence that liquid has been allowed to enter the monitor voids the warranty.
noTE! obstructions or dirt on the sensor’s red light or detector may cause a sensor failure. Make sure
there are not obstructions and the sensor is clean.
noTE! If the oximeter parameter is being monitored, the pitch of the pulse beep is determined by the
Spo
2
value. The higher the Spo
2
value, the higher the pulse beep pitch; the lower the Spo
2
value,
the lower the pulse beep pitch.
noTE! The low Spo
2
alarm limit minimum test value is 85. If you change the low Spo
2
alarm limit to a
value less than 85 and then change the patient type, add a new patient, or power down/power up
the monitor, a minimum value of 85 takes the place of the value you entered.
