To judge the patient activity (heart rate) and triggering to allocate
the pulse amplitudes of the ICP pulse wave

V / V / mmHg
*1: The pressure input units (three 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
