From: The pulsating brain: A review of experimental and clinical studies of intracranial pulsatility
Examples of pressure wave recordings. An example of mean wave amplitude measurements taken from a clinical case at Oslo University Hospital, and showing simultaneous intracranial pressure (upper) and radial artery pressure (lower) waveforms. Automatic detection of pressure peaks and valleys allows for automated calculation of mean pressure, pulse amplitude (mean wave amplitude), and pulse latency (relative to the radial artery pulse pressure, 80 ms in this case).
