Biomechanical Effects of Incisional Negative Wound Pressure Dressing: An Ex Vivo Model Using Human and Porcine Abdominal Walls

Figure 4

Pressure values in the porcine model using the balloon method (14 measurements with mean value and standard deviation), both the original PREVENA dressing (OPD) and the self-made epicutaneous dressing (SMD). Pressure differences were added to the previous pressure steps.
