4.9.1 Physiological alarms
Pressure alarms (for all available measuring locations including pO2, however excluding CPP) have been
designed as alarms with high priority. All other alarms have been designed as alarms of medium priority.
The CPP has been designed as an alarm of medium priority.
The delay of the alarm condition amounts to a maximum of 15 sec. + measuring interval. For the
measurement of the partial oxygen pressure, the measuring interval, for example, can be set to a maximum
of 60 sec. which results in a delay of the alarm condition of a maximum of 75 sec. (15 sec. + 60 sec.).
The apparatus monitors the following physiological alarms:
Pressure value outside of range
The alarm is activated, if the limiting value is exceeded or fallen short of for 6 seconds within an interval of
10 seconds.
The following measured values can be monitored:
-
ICP: medium pressure, amplitude, CPP
-
ABP: systolic and diastolic pressure, medium pressure
-
GP1 – GP3: systolic and diastolic pressure, medium pressure
-
CVP: medium pressure
Note: The pressure measurement input units (two input units and all available measuring locations)
have been provided with a cyclic self-test. In regular intervals, a test pulse of defined value
(approx. +70 mmHg) is transferred to the measuring signal of the pressure sensor, and the
amplitude is then evaluated. Under the highly unlikely assumption that at the measuring location
of ART (with relatively high physiological pressure values) a pressure sensor with the permissible
maximum offset error of +150 mmHg and a measured pressure value MAP of > 320 mmHg and
in addition a test pulse of approx. +70 mmHg meet upon each other, there is a very low probability
that this would cause a technical alarm
?
.
pO2 outside of range
The alarm is activated, if the limiting value is exceeded or fallen short of for 6 seconds within an interval of
10 seconds.
Note: The amplitude of the pO2 measuring signal is monitored. The value of the amplitude is displayed
on the Overview screen 1. If the amplitude drops below a value of 370, a sensor alarm “Sensor?”
is released.
Temperature outside of range:
The alarm is activated, if the limiting value is exceeded or fallen short of for 6 seconds within an interval of
10 seconds.
The following shall apply for all physiological alarms:
-
The adjustment range for the alarm limits comprises the entire measuring range.
-
Every alarm can be activated / deactivated separately (cf. chapter digital display).
-
In case of an alarm, an alarm of high (invasive pressure) or medium priority (temperature) is activated
and the measured value concerned starts flashing.
-
The apparatus automatically switches into the display mode (if no menu has been opened).
AUDIO OFF only switches the acoustic signal off. The value flashes until it is outside of range.
