ALARM INDICATIONS
A N D
INTERPRETATION
All alarm indications are accompanied by an audio signal
unless the SILENCE switch is in the ON state. In the
SILENCE (ON) state, an alarm condition (other than a
microprocessor system failure) is indicated by the flashing
yellow LED indicator.
A microprocessor system failure will generate a continuous,
high level audio alarm regardless of the setting of the
SILENCE switch.
There are two categories of alarms, patient alarms and
system alarms; these are described in the paragraphs
following.
PATIENT ALARMS
Patient alarms include those alarms issued when the
patient's systolic pressure, mean arterial pressure, pulse
rate, or diastolic pressure is outside the set limits.
Whenever one of these conditions occurs, the associated
display (SYSTOLIC, MAP, PULSE, or DIASTOLIC,) will
flash the determined value and an alternating high/low
frequency audio alarm will be issued.
Pressing the SILENCE (ON/OFF) switch to on (yellow LED
lit) silences the audio alarm, but the alarming parameter
display and SILENCE LED indicator will continue to flash at
the same rate.
Pressing the CANCEL switch cancels all patient alarm
indications.
Whenever the monitor detects a patient alarm condition in
auto mode, the monitor activates the alarms, waits 15
seconds and then begins one more determination (unless
CANCEL is pressed). If the alarm condition persists, no
further determinations are made until the cycle time
elapses.
SYSTEM ALARMS
There are a number of system level alarms to alert the
operator to certain abnormal conditions or internal system
failures. See Table 5-3, System Alarms Summary Table.
Alarm conditions and remedies are discussed in this
section, Troubleshooting.
Pressing the CANCEL switch cancels all excess time
system alarms, 855, 844, 833, 899, and the 800
overpressure alarm.
