Quizplus · Accepted Answer

DIntracranial pressure (ICP) waveforms consist of three peaks: P1 (percussion wave), P2 (tidal wave), and P3 (dicrotic wave). Normally, P1 is the highest, reflecting arterial pulsations. When intracerebral compliance decreases, the brain's ability to buffer changes in volume worsens, leading to alterations in these waveforms. A P2 greater than P1 indicates decreased compliance, as the brain's buffering capacity is overwhelmed, making the brain more susceptible to changes in blood volume. Similarly, a P3 greater than P1 and P2 indicates very poor compliance, as even the dicrotic wave, which normally is the smallest, becomes the largest, reflecting severely compromised brain compliance.
