Hi Megan! Thanks for this question! Normal values for ICP vary slightly depending on the reference. Generally, values less than 15 mmHg are considered normal. Values greater than 20-25 mmHg usually require treatment. On the NCS exam, they likely won’t ask questions requiring you to determine next steps on the gray areas (10-20 mmHg).

Here are a few values from the literature:
– Supine adult [1]: 7-15 mmHg
– Standing adult [1]: -10 mmHg
– Normal values in adults and older children [2]: <10-15 mmHg
- Mild intracranial hypertension [2]: 20-30 mmHg
- Severe, life-threatening hypertension [2]: >40 mmHg
