WARNING: Check Target Range alarm limits to ensure they are appropriate for
the patient being monitored with each use. Ensure Target Range alarm limits
do not exceed the standard thresholds set by the institution.
WARNING: If you plan to monitor the patient using alarms, do not set the
Target Range alarm limits to extreme values that render the monitoring
system ineffective. Ensure Target Range alarm limits are appropriate for each
patient.
WARNING: If you plan to monitor the patient using alarms, do not pause,
disable or decrease the audible alarm volume until you verify that the patient
is being monitored by other means, such as direct observation, as this could
compromise patient safety.
WARNING: If you plan to monitor the patient using alarms, do not decrease the
adjustable alarm volume below ambient sound levels. Decreasing the alarm
volume below ambient levels might impede operator recognition of the
audible alarm, which might lead to patient harm during an alarm situation.
