12. TECHNICAL SPECIFICATIONS
Frequency response
The maximum frequency response of the AURA™ ICP
Monitoring System, including the ICP readout display, at
peak pressures of 10, 20, and 50 mmHg.
Slew rates
The slew rates (the system's fastest output during a
unit of time) from zero to peak and peak to zero for
peak pressures of 10, 20, and 50 mmHg.
Time constants
The time constants for full-scale deflection of the
system, with both increasing and decreasing pressure.
Pressure range of t
including display range.
Accuracy of ICP range.
Length of time over which the device will maintain
the specified accuracy.
Pressure stability over temperature.
The expected drift of the zero-point reading of the
AURA
Sensor.
