1. An absorbent pad for covering a patient support structure, the absorbent pad comprising:
a periphery having a first portion and a second portion;
a liquid permeable layer;
a liquid impermeable base layer;
an absorbent layer positioned between the liquid permeable layer and the liquid impermeable layer;
a first sensor positioned between the liquid permeable layer and the liquid impermeable layer, the first sensor indicating when exudate is present at the first sensor; and
a second sensor positioned between the liquid permeable layer and the liquid impermeable layer, the second sensor indicating when exudate is present at the second sensor;
wherein the first sensor is positioned in a central portion of the absorbent pad and is not positioned adjacent to the periphery; and
wherein the second sensor is separated from the first sensor by a first distance, the second sensor is positioned adjacent to the first portion of the periphery and is not positioned adjacent to the second portion of the periphery, and the second sensor indicates that fluid has reached an edge of the patient support structure at the first portion of the periphery.
