![]() The largest ΔICP was 5 mmHg obtained when ICA volume and ROC were 20 ml and 1,600 ft/min, respectively. However, ΔICP was independent of the initial ICP. the difference between mean cruising ICP and initial ICP, was found to increase with ICA volume and ROC. The setup can measure the rise in ICP during depressurization to levels similar to that inside the cabin at cruising altitude. The cabin was replicated using a custom-made pressure chamber. ![]() ![]() It consists of an acrylic box (skull), air-filled balloon, water-filled balloon (cerebrospinal fluid and blood) and agarose gel (brain). We propose an experimental setup that simulates the intracranial hydrodynamics of a pneumocephalus patient during flight. This study investigates the effects of aircraft cabin pressure on intracranial pressure (ICP) elevation of a pneumocephalus patient.
