Figure 3From: Effect of amplitude and duration of impulsive pressure on endothelial permeability in in vitro fluid percussion trauma Combination of amplitude and duration of positive pressure and negative pressure. Open circles and open squares indicate pressures generated using a 1 and a 2 kg weight struck with a pendulum, respectively. The amplitudes are 53–1348 kPa and the durations are 9–29.1 ms in positive pressure (A). The amplitudes are −52–−93 kPa and the durations are 42.9–179.5 ms in negative pressure (B).Back to article page
