Fig. 4From: A novel approach to CSF pressure measurement via lumbar puncture that shortens the measurement time with a high level of accuracyThe behaviour of spinal needle-spinal manometer assembly is exponential. 22G Pajunk Sprotte, 22G B Braun Spinocan and 22G M. Schilling needles connected to a manometer with a final equilibrium of 13cmH2O is displayed. The graph is the plot of data from Table 2Back to article page
