Amplitude Analysis of Intracranial Pressure Recordings

Accuracy of ventricular volume estimation.

“…The presence of B waves and the width of intracranial pressure pulse have been suggested to be of prognostic significance in patients with normal pressure hydrocephalus (Symon and Dorsch, 1975;Belloni et al, 1976). Attempts have been made to measure indices of brain compliance (Brock et al, 1975;Avezaat etal., 1976;Marmarou et al, 1976;Szewczykowski et al, 1976;Sullivan et al, 1978). The clinical significance of a certain value for compliance in large ventricles compared with that in small ventricles is, however, not clear (Miller et al, 1975), and so ventricular volume is a parameter which should be considered when assessing the results of intracranial pressure measurement.…”
