Table 2 Assigning scores to parameters in the pressure ulcer scale for healing tool

Parameter	Description	Score
Surface area	Determined by multiplying the greatest length by the greatest width	0-10
	0 cm²	0
	< 0.3 cm²	1
	0.3-0.6 cm²	2
	0.7-1.0 cm²	3
	1.1-2.0 cm²	4
	2.1-3.0 cm²	5
	3.1-4.0 cm²	6
	4.1-8.0 cm²	7
	8.1-12.0 cm²	8
	12.1-24.0 cm²	9
	> 24.0 cm²	10
Exudate (drainage)	Assessed at dressing removal before applying a topical agent	0-3
	None	0
	Light	1
	Moderate	2
	Heavy	3
Tissue type		0-4
Closed/resurfaced	The wound is completely covered with epithelium/new skin	0
Epithelial tissue	New pink or shiny tissue/skin growing in from the edges or as islands on the ulcer surface (for superficial ulcers)	1
Granulation tissue	Pink or beefy red tissue with a shiny, moist, granular appearance	2
Slough	Yellow or white tissue adhering to the ulcer bed in strings or thick clumps, or is mucinous	3
Necrotic tissue/eschar	Black, brown, or tan tissue adhering firmly to the wound bed or ulcer edges, may be firmer or softer than surrounding skin	4
Total PUSH score	Obtained by summing the scores for the above three parameters	0-17
