Final answer:
Normal intracranial pressure (ICP) is 10 to 15 mmHg. Levels above this can indicate potentially harmful conditions affecting brain function and growth.
Step-by-step explanation:
The normal range for intracranial pressure (ICP) is 10 to 15 mmHg. It's important to maintain ICP within this range to ensure proper cerebral perfusion and brain function. Elevated levels, such as those referenced where the gauge pressure surrounding an infant's brain may rise as high as 85.0 mm Hg, can be harmful and lead to conditions such as hydrocephalus, where an outward force can cause abnormal skull growth. In adults, levels above the normal range may indicate issues like brain swelling due to injury or illness.
