Asystole delay
...................... 1, 2, 3, 4 , 5 ... 14, 15 seconds
See
Bradycardia delay
, but for asystole
RR averaging
......................... 2. 4, 6, 8 ... 14, 16 beats
Number of heartbeats used to calculate
the heart rate –
the displayed heart rate used to detect
alarm conditions is calculated as an av-
erage value over the number of heart-
beats set here. The greater the value
chosen for RR averaging, the slower the
system’s reaction, particularly in the
event of bradycardia, to report an
alarm.
Averaging interval ............
10, 20 ... 60 ... 110, 120 seconds
The average heart rate measured over
the set interval yields the reference
value for calculating
Trend deviation
(+)
and
Trend deviation (-)
.
Trend deviation (+) .............
5, 10, 15, 20, 25 , 30, 35, 40, 45, 50%
The current heart rate is compared with
the average heart rate measured over
the averaging interval and an alarm is
reported when the set percentage de-
viation is exceeded. This alarm is re-
ported only when
Heart rate alarms
is
set to
Limits & trends
.
Trend deviation (–) .............
See
Trend deviation (+)
, but the value
falls below the set percentage deviation.
50 Hz filter ............................
Setting the 50 Hz filter to
On
sup-
presses interference signals, but also fil-
ters out parts of the ECG signal.
