estimated P2/P1 ratio for risk of intracranial hypertension and compliance progression
In-app live P2/P1 ratio trend
PDF report with ratio trend
- P2/P1 > 1.4 with 90% specificity to assess risk of IH*
- P2/P1 > 0.8 and < 1.2 for baseline from healthy population*
- P2/P1 < 0.8 with 92% sensitivity to rule out IH*
The automated estimation of P2/P1 is offered by the B4C System as a derived parameter for more accurate interpretation.
P2’s relative amplitude higher than P1 suggests a loss of the compensatory reserve mechanisms and a deterioration of intracranial compliance that indicate increased risk of intracranial hypertension.
Observe the three types of waves for interpretation:
normalized time-to-peak for risk of intracranial hypertension
In-app live ttp trend

- nTTP > 0.3 with 92% specificity to assess risk of IH*
- nTTP < 0.3 baseline from healthy population*
The automated calculation of the normalized time, from pulse’s start, to the highest peak is offered by the B4C System as a derived parameter for more accurate interpretation.
If the largest peak occurs later in the pulse’s timeline, it is likely that this peak is the waveform’s tidal wave (P2). If the time to peak occurs earlier in the timeline, it likely represents the waveform’s percussion wave (P1).
