11 Technical parameters (Specification)
11.1 Technical data
Temperature

15 ... 25 °Celsius: ± 0.2 K (plus ± 0.2 K of the sensor)
Scanning rate: 1 Hz
Defibrillation protection: Yes
Invasive blood pressure
Number of channels: 2
Designation of the measuring location: ART, CVP, ICP1, ICP2, GP1, GP2, GP3
Measuring ranges: - 20 ... + 400 mmHg *1
Offset range: - 150 ... + 150 mmHg *1
Resolution of the pressure values: 0.1 mmHg
Accuracy: ± 1.5 mmHg (cf. operating temperature, plus pressure sensor
error)
Scanning rate: 100 Hz
Defibrillation protection: Yes
Pressure sensor
Supply voltage: 4.46 V ± 0.1 V
Direct impedance of the sensor: > 1 kΩ
Sensitivity of the sensor: 5 µV / V / mmHg
*1:
The IBP 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 ?
Partial oxygen pressure
Number of channels: 1
Designation of the location of the
measurement: pO2
Measuring ranges: 0 ... + 30 mmHg
Resolution of the pressure values: 0.1 mmHg
Measuring interval: 1 s, 5 s, 10 s, 20 s, 60 s, off
Defibrillation protection: Yes
Oxygen sensor: fibre-optical
Light source: green LED
Sensitivity of the sensor: characteristic saved in the apparatus; catheter parameters in the
EEPROM in the catheter connector
Accuracy: ± 3 % of the measured value or ± 2.5 mmHg – the higher value
is applicable for the partial oxygen pressure < 120 mmHg
< 10 % of the measured value for the partial oxygen pressure
120 mmHg to 200 mmHg (cf. 4.4.3.8
Technical alarms during
partial oxygen pressure measurement)
