Intracranial pressure waveform changes characterized by different categories of ICP and occurring due to coughing and bending

A) Patients ICP recordings were grouped by mean ICP into < 18.4 mmHg (25 cmCSF), 18.4–22.1 mmHg (25–30 cmCSF) and > 22.1 mmHg (30 cmCSF). As mean ICP increases amplitude of the waveform increases significantly (p < 0.0001). ANOVA. Data presented as mean ± standard error of the mean. *P = < 0.05, ****P = < 0.0001. ICP was recorded during the performance of coughing and bending. Graphs show trough to peak changes in ICP in mmHg with cough (B) and bend (C), showing absolute ICP changes in ICP. n = 15 (B-C. Paired t-test. Data presented as mean ± standard error of the mean
