View larger version (24K): [in a new window]   FIG 3. A–C, This readout from the Doppler device shows the multiple reflections from the bubbles in the flush solution (A). After degassing the solution (B) and allowing the syringe to sit undisturbed for 30 seconds (C), there was an evident reduction in bubble events. A statistical analysis of this data was not available
