This problem is not caused by insects or disease but is a way the plant reduces water loss from its leaves during cold, dry, windy weather. Plants should recover when the weather warms again. Table 1.
Purpose: To reduce the number of health careâacquired pressure ulcers (HAPUs) in patients in the cardiac surgery intensive care unit (CVICU) and to develop nursing processes to prevent HAPUs, thus reducing morbidity, mortality, and cost.
Two additional stages of pressure ulcer formation were added in 2007: 1  Suspected Deep Tissue Injury: Area of localized discolored intact skin that is purple or maroon-red in color. 2  Unstageable Pressure Ulcers: Full-tissue thickness loss where the base of the ulcer is covered by slough or an eschar. The true depth of the damage cannot be determined until the necrotic tissue is cleared away or the eschar removed and the base of the pressure ulcer is visible.
