Proportional changes in volumes of intracranial compartments and ICC in spatial compensation and decompensation phases. Under normal physiological and compensatory conditions, ICC is high, indicating that there is spare space in the cranium and ICP remains relatively stable. However, in the decompensation phase, due to abnormal increases in overall intracranial volume, ICC becomes critically low, resulting in high ICP values. In this phase, any additional volume added will cause ICP to increase exponentially
