1. A wound dressing apparatus comprising:
a wound dressing comprising:
a first layer comprising a proximal wound-facing face, a distal face opposite the proximal wound-facing face, and one or more apertures;
a cover layer configured to cover and form a seal over a wound and the first layer;
an electronics assembly comprising a negative pressure source; and
a non-adhesive film beneath the proximal wound-facing face of the first layer at least when negative pressure is applied;
wherein a portion of the cover layer overlying the one or more apertures in the first layer is configured to be compressed within the one or more apertures in the first layer and contact the non-adhesive film when negative pressure is applied to the wound dressing apparatus;
wherein the compressed cover layer indicates a level of negative pressure below the cover layer.
