Queckenstedt's test repurposed for the quantitative assessment of the cerebrospinal fluid pulsatility curve.

This technical note describes a method to reliably derive, beyond gross CSFP increments, metrics related to cardiac-driven amplitudes during QT (i.e., RPPC-Q). A study comparing these metrics as obtained by established procedures (i.e., infusion testing) and by QT is warranted.
