Force required to remove foam and gauze from a porcine wound after 72 hours of dressing application without negative pressure (no negative pressure wound therapy [NPWT]), continuous NPWT, intermittent pressure therapy (IPT), or variable pressure therapy (VPT). The force was plotted as a function of time, and the average force was calculated. The results are shown as means ± SEM of 8 experiments. Note that more force is needed to remove foam than gauze.
