CSF Physiology, Pressure & Dynamics
Lundberg pressure waves
Lundberg pressure waves are patterns of fluctuating intracranial pressure seen on pressure monitoring, some of which signal reduced reserve.
In short: Lundberg pressure waves
- They are patterns of changing intracranial pressure over time.
- Certain waves (A waves) indicate dangerously reduced compliance.
- They are seen during intracranial pressure monitoring.
- They can inform decisions about treatment.
What it is
Lundberg pressure waves are characteristic patterns of fluctuating intracranial pressure observed during continuous pressure monitoring. They are named after the researcher who described them and are categorized into types (notably A, B, and C waves).
Understanding Lundberg pressure waves
During intracranial pressure monitoring, the pressure is not perfectly steady but fluctuates in patterns. Lundberg A waves (also called plateau waves) are sustained, large rises in pressure that indicate seriously reduced intracranial compliance and can be a warning sign. B waves are shorter, rhythmic fluctuations that may also reflect impaired compliance. Recognizing these waves helps clinicians assess how much reserve the brain has and can inform decisions about whether and how to treat raised pressure. They are a more technical aspect of pressure monitoring.
Why it matters
Understanding Lundberg pressure waves helps families see that intracranial pressure monitoring reveals patterns, not just a single number, and that certain patterns warn of reduced reserve and can guide treatment decisions.
Common questions
What are Lundberg pressure waves?
Patterns of fluctuating intracranial pressure on monitoring.
Which are concerning?
A waves (plateau waves) indicate seriously reduced compliance.
How are they detected?
During intracranial pressure monitoring.
Bottom line
Lundberg pressure waves are patterns of fluctuating intracranial pressure; certain types warn of reduced reserve and can guide treatment.
