64 Alarms, displays, and views during monitoring
Message Meaning Information No.
Apnea
detected!!!
A respiration signal has
not been detected for
longer than the set
Apnea delay.
When there is no apnea:
-
The electrodes are badly placed, i.e. the
signal is too small to be detected.
-
Cardiogenic artifacts are superim-
posed on the respiration signal so that
it is rejected.
-
The monitor, cable, or electrode is
defect.
-
The set
Apnea delay
is too short.
10
ECG
amplitude
low!!!
The monitor could not
detect the ECG signal for
longer than the set
Asystole delay.
When there is no asystole (cardiac arrest
or delay):
-
The electrodes are badly placed.
-
The ECG signal is too small to be
detected.
-
The monitor, cable, or electrode is
defect.
5
Heart rate
and
apnea!!!
A heart rate alarm and an
apnea alarm have
occurred simultaneously.
See the messages and information for
“Heart rate too high/ too low” and
"Apnea detected”.
3
Heart rate
too high!!!
The calculated heart rate
exceeds the set
Upper
limit
for longer than the
set
Tachycardia delay.
When there is no tachycardia:
-
T wave peaks are interpreted as R
waves so that the calculated heart rate
is too high.
-
The electrodes are badly placed.
-
Artifacts caused by excessive move-
ment trigger false alarms.
-
50 Hz or other sources of electromag-
netic interference trigger false alarms:
suspected interference sources must
be removed
-
The electrode has become detached.
-
The monitor, cable, or electrode is defect.
-
The set
Upper limit
is too low.
