1. Apparatus for instantaneously processing data relating to intracranial pressure to display an immediate amplitude analysis of the data comprising:
- means responsive to intracranial pressure;
classifying means sensing a predetermined number of pressure ranges;
a plurality of pressure range counters, said classifying means entering a sensed count pulse in the corresponding pressure range counter as the pulse is received;
percent calculator means calculating the number of counts in each pressure range counter divided by the total number of pressure count samples processed;
percentage memory means storing each calculated result from said percent calculator means;
display means illustrating bar graph and numerical data; and
display selector means selectively actuating said display means illustrating bar graph and numerical data.

Abstract
The present invention relates to a method of and apparatus for processing physiological information and particularly to a method and device for the processing of intracranial pressure data, such as the information which is sensed by a transducer amplifier responsive to a patient'"'"'s intracranial pressure. The invention is especially suitable for use in processing intracranial pressure readings over a period of time to obtain data which may be useful in prognosis.

11. The method of instantaneously processing data relating to intracranial pressure to provide an immediate amplitude analysis of the processed data comprising the steps of:
- receiving intracranial pressure pulses from a responsive transducer;
instantaneously grouping the pulses into a predetermined number of pressure ranges;
calculating the number of counts in each range divided by the total number of pressure pulses processed; and
displaying immediately data, said data being a histogram formed by plotting the number of count samples expressed as percentages of the total pulses against the individual pressure ranges. - View Dependent Claims (12)
