FIGURE 4

Ratios of exudate‐simulant fluid, which remained in the wound cavity plus any fluid spillovers onto the peri‐wound environment (if applicable, as per the results in Figure 3), over the corresponding volume of the fluid retained in the dressing. These ratios are plotted for the prone (off‐loaded; A,B) and supine (non‐off‐loaded; C,D) test configurations, and for the low (A,C) vs the high (B,D) exudate‐simulant viscosities, after 12, 24, and 30 hours of simulated use. We note that either pooling of fluid in the wound cavity or spillovers may be harmful, and, therefore, the smaller the value of this parameter, the better. The error bars are the standard errors from the mean values of three test repetitions per test configuration and an asterisk indicates a statistically significant difference in the relevant outcome measure (P <  .01). FBD, foam‐based dressing; MPD, multipurpose dressings; SAD, superabsorbent dressing
