B waves are elevations of mean ICP that may have different patterns. Column A illustrates the trend of mean ICP and column B the computer-generated examples. (1) B waves with symmetrical shape and amplitude < 10 mmHg. (2) B waves with symmetrical shape and amplitude > 10 mmHg. (3) Symmetrical B waves with plateau. (4) Asymmetrical B waves. The timescale is in the order of minutes. It should be noted that amplitudes of B waves and single ICP waves are fundamentally different.
