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.
NOTE: The low SpO
2
alarm limit minimum test value is 80. If an operator changes the low SpO
2
alarm
limit to a value less than 80, and a power down - power up sequence takes place, a minimum value
of 85 takes the place of the operator entered value.
NOTE: SpO
2
averaging is the number of pulse beats over which the SpO
2
value is averaged; pulse
averaging is the number of seconds over which the pulse value is averaged.
ECG Warnings, Cautions and Notes
WARNING! PACEMAkER PATIENTS. Rate meters may continue to count the pacemaker rate during
occurrences of cardiac arrest or some forms of arrhythmia. Do not rely entirely upon rate
meter alarms. keep pacemaker patients under close surveillance. See this manual for
disclosure of the pacemaker pulse rejection capability of this instrument.
WARNING! PACEMAkER PATIENTS: If PACE DETECT is not turned on when monitoring pacemaker patients
the heart rate readouts derived from the ECG patient connections are likely to display
erroneous high or erratic rates. keep pacemaker patients under close surveillance. For
pacemaker patients it may be advisable to select the SpO
2
parameter as the primary heart
rate source.
WARNING! Connect only three-lead or five-lead ECG lead wires from the patient to the ECG patient cable.
Do not connect any other signal source to the ECG patient cable.
WARNING! False low heart rate indicators or false Asystole calls may result with certain pacemakers
because of electrical overshoots.
WARNING! Reliable monitoring of pacemaker patients can only occur with the pace detect on.
WARNING! The pacemaker spike shape and size is not to be diagnostically interpreted.
WARNING! keep pacemaker patients under close observation. Rate detection in the software may
continue to count the pacemaker rate during cardiac arrest and/or arrhythmia conditions.
Therefore, do not rely solely on rate detection alarms.
WARNING! Do not use line isolations transformers with this monitor. Line isolation monitor transients
may resemble actual cardiac waveforms and thus inhibit heart rate alarms.
WARNING! Electrodes of dissimilar metals should not be used.
NOTE: Follow institutional standards when applying ECG electrodes. Silver/Silver Chloride disposable
electrodes are strongly recommended to avoid polarization effects that result in large input offset
potentials. Use of “squeeze bulb” type electrodes is not recommended.
NOTE: Use only standard AAMI three-lead or five-lead ECG cables.
NOTE: The ECG patient circuit is electrically isolated.
