Cannot be assumed to be evenly distributed particularly in pathological states with intracranial hypertension Pressure gradients may exist between different tentorial compartments CSF pressure usually represents global ICP but relies on unobstructed flow Related...
The normal ICP trace looks similar to an arterial trace but has 3 distinct peaks: P1Percussion Wave P2Tidal wave P3Dicrotic notch The arterial systolic pressure transmitted from the choroid plexus Thought to represent true ICP proper as a correlate of the arterial...
ICP >15 mm Hg is elevated Management is mostly extrapolated from TBI where treatment is recommended for ICP >22 mm Hg (Brain Trauma Foundation Guidelines): Values above this level are associated with increased mortality However, this single threshold is probably...
With increasing ICP there is decreased compliance of the brain resulting in a change in the morphology of the ICP waveform: Increases in amplitude P2 exceeds P1 Becomes broader and ’rounded off’ Related Pages: (5.6)...
Rhythmic variations in ICP described first described by Lundberg in the 1960’s Clinically less useful in modern practice, with an emphasis on earlier recognition and treatment of raised ICP meaning A waves rarely seen: Type Description Example Implication A-wave...
