Question

ICP is normally 0–10 mm Hg; at 20–25 mm Hg, the upper limit of normal, treatment to reduce ICP is needed.

once the ICP has reached around 25 mmHg, small increases in brain volume can lead to marked elevations in ICP

ICP is very likely to cause severe harm if it rises beyond 40 mmHg in an adult.An increase in pressure, due to head injury leading to cerebral edema can crush brain tissue, shift brain structures, and

cause the brain to herniate,restrict blood supply to the brain, leading to an ischemic cascade.Even ICP between 25 and 30 mm Hg are usually fatal if prolonged, except in children, who can tolerate higher pressures for longer periods

Thank you friends dad is fluctuating between 15 and 30 after 4 wheeler accident... If its only briefly 25+ and usually 15-20 for days is that likely to cause brain damage
