Figure 2From: In vitro hydrodynamic properties of the Miethke proGAV hydrocephalus shuntShapes of pressure-flow curves for the three shunts tested at three different pressure settings: 4 cm H2O, 10 cm H2O and 16 cm H2O (left to right). The pressure units used for these measurements were mm Hg. However the manufacturer used cm H20 for the settings on the shunts.Back to article page
