Zusammenfassung:	Wound dressing comprising a cover layer 18200 configured to form a seal around the wound, a nitrite providing layer 18600 comprising a nitrite salt, an acid providing layer 18400 positioned below the cover layer, comprising acidic groups, wherein the acid-providing layer comprises a window at the centre, and a central absorbent material 18450 positioned within the window of the acid providing layer for absorbing wound exudate. When the wound dressing is applied, the acid-providing layer may be positioned above a skin around the wound or an edge of the wound, and/or the central absorbent material may be positioned above the wound. The central absorbent layer may be fully encompassed by the acid-providing layer. The dressing may further comprise an acquisition distribution layer 18800 configured to horizontally wick fluid; and/or a frame layer 18100 defining a window 18110 at the centre, wherein the nitrite-providing layer may be positioned within the frame layer window. The acid-providing layer may comprise xerogel or hydrogel. Also disclosed a wound dressing comprising a cover layer, a nitrite providing layer, and an acid providing layer positioned below the cover layer, wherein the acid-providing layer comprises a window at the centre of the layer.
