Figure 2From: Sternum wound contraction and distension during negative pressure wound therapy when using a rigid disc to prevent heart and lung rupture Sternotomy wound contraction upon application of NPWT (-40, -70, -120 and -170 mmHg) with and without a rigid disc between the heart and the sternum. Results are presented as mean values of 8 measurements ± S.E.M. It can be seen that the degree of wound contraction is similar in both settings.Back to article page
