Patient Alarms - Welch Allyn Atlas Operator's Manual

3.1 Patient Alarms

Patient alarms sound when one of the patient's vital measurements is registering outside the limits you
have set. You can set high and low alarm limits for most of the measurements. Setting and checking the
alarm limits can be easily done from the front panel. The alarm settings can be saved as defaults by
accessing a menu. Patient alarms trigger a Print On Alarm, if Print On Alarm is configured.
A Patient Alarm is a signal that some vital
measurement is outside the limits that were set
by you. Patient alarm limits assume preset
values when the monitor is first turned on and it
is easy to change the limits at the front panel.
Setting alarm limits – The front panel of the
monitor has 2 sets of Select and Set buttons.
One set is on the right side of the monitor, and
one set is on the left side. To set a patient alarm
limit, use one of the Select buttons and follow
these steps:
•
Press the button on the side of the
Select
monitor closest to the measurement you
want to change several times until the limit
you want to change flashes. Successively
pressing this button cycles through the
settings for each different measurement.
These numbers and the
will slowly flash. The flashing numbers
show the current alarm limit.
•
While the alarm limit you want to change is
flashing, press the top or bottom half of the
button. This changes the alarm limit.
Set
Note: The alarm limits do not wrap around at the
upper and lower end of their legal values.
Instead, the number stops changing when you
reach the upper or lower measurement limit
of the instrument.
•
When you are satisfied with this alarm limit,
press again to move to another
Select
patient alarm.
•
To exit alarm limit setting and return to
normal mode, press
alarm limits or
HI
or indicator
HI LO
until there are no
Select
or indicators flashing.
LO
Note: If the buttons are not pressed for 10
seconds, the unit will automatically revert to
its normal mode.
Silencing patient alarms – The
turns off all audible alarms - patient alarms and
other types - for a short period. Any vital
measurement that is outside its limits will flash,
showing which measurement is out of range.
Any other measurements that go outside their
limits during the current silence period will also
flash, but will not trigger the audible alarm
during the silence period. When alarms are
silenced, they will not trigger a Print On Alarm.
When the silence period is over, an alarm that is
still active will trigger a Print On Alarm if the
Print On Alarm configuration is set to Yes.
Suspending patient alarms – You can suspend
patient alarms individually, which means that
the specific measurement will not sound the
audible alarm when it goes outside the limits.
However, this value will still flash whenever it is
outside the limits, giving you a visual indication
of an alarm condition. When an alarm is
suspended, it will not trigger a Print On Alarm.
When the alarm is unsuspended, an alarm that is
still active will trigger a Print On Alarm if the
Print On Alarm configuration is set to Yes.
