Message Priorities
72 Portable Bedside Capnograph/Pulse Oximeter
The Alarm Review screen will display alarms for the past hour, if the monitor has been running for an hour or
more. If the monitor has been running for less than an hour, the screen will display data from the time the
monitor was turned on. If the trend memory was cleared, data from the time the trend memory was cleared will
be shown.
Message Priorities
Alarms and advisory messages are displayed in the header area of the monitor in order of priority. When there is
an alarm, only the alarm messages will appear in the message area, and advisory messages will not appear until
the alarm condition is cleared. For example, if there is a
RR HIGH ALARM
, this alarm message will appear in
the message area, and the advisory message SPO
2
WEAK. REPOSITION SENSOR. will not appear even
though the condition exists to generate this message.
If more than one alarm condition exists, the monitor will display each alarm message for about 4 seconds and
continue to repeat the messages in turn until the alarm conditions are cleared. For example, the
RR HIGH
ALARM
and
SpO
2
LOW ALARM
messages will alternate in the message area.
If no alarm condition exists but more than one advisory message condition exists, the advisory messages will
each appear for four seconds as described above. The advisory messages will continue to appear until the
condition clears or an alarm condition occurs and the alarm message is displayed instead of the advisory
message.
Alarm Delay
Capnostream provides the option to delay alarms (both the audible alarm and the alarm indicator on the screen)
by a number of seconds. If this option is used, the alarm signal (audio or visual) will only appear if the alarm
condition continues to be present past the delay time which has been set.
EtCO
2
, RR and PR High Alarms and SpO
2
and PR Low Alarms can be delayed by 10, 15, 20, or 30 seconds, or
not at all (Alarm Delay disabled). The default option is Alarm Delay disabled. This option is available for all
patient types.
The Alarm Delay can be set from the Institutional Defaults screen, which can be reached by
SYSTEM>SERVICE>Input Service Password>INST DEFAULTS>ALARM LIMITS>SET ALARM
DELAY
.
Types of Alarms
High priority patient alarms (urgent) indicate that the particular parameter has exceeded the set limit. A default
alarm limit is provided for each alarm situation. Alarm limits can be changed to fit the particular institution, if
desired.
In addition, Capnostream provides the possibility to set a caution alarm for patient alarms at a lower value level
than that set for the standard high priority patient (urgent) alarm, to provide information for caregivers and
allow the caregiver to address a developing situation before it is critical. By default these caution alarms are
disabled. If they are enabled, a limit which is between the high priority alarm limit and the normal (healthy)
level is provided for each alarm situation and may be set to provide a caution alarm. To enable these caution
alarms, see
Changing Alarm Limits on page 79 .
The associated numeric on the display will blink yellow if the numeric has reached the caution alarm limit or
red if it has reached the high priority patient (urgent) alarm limit. Also, the red alarm LED and yellow caution
alarm LED will light appropriately. If a user does not wish to use this caution alarm on any particular alarm, he
can set both the high priority patient (urgent) alarm and caution alarm for that alarm to the same limits (see
Changing Alarm Limits on page 79 ). Then only the high priority patient (urgent) alarm will occur. You can also
revert to a single level system for all alarms by pressing the button for Caution Disable.
All recording and digital reporting of patient alarms involves both the high priority patient (urgent) alarms and
the caution alarms.
