The long-term objective of this research is to improve pressure ulcer prediction and prevention in critically ill adults. The primary purpose of this study is to determine whether critically ill adult patients who develop pressure ulcers have less tissue tolerance for pressure than those who do not develop pressure ulcers. A secondary purpose is to examine the general risk factors for pressure ulcer development in the adult critical care population.

520 $a The long-term objective of this research is to improve pressure ulcer prediction and prevention in critically ill adults. The primary purpose of this study is to determine whether critically ill adult patients who develop pressure ulcers have less tissue tolerance for pressure than those who do not develop pressure ulcers. A secondary purpose is to examine the general risk factors for pressure ulcer development in the adult critical care population.
520 $a A prospective cohort design, utilizing an experimental protocol, was selected for this study. Twenty-seven critically ill patients meeting a set of inclusion criteria were enrolled in the study within 72 hours of AICU admission. On prospective follow-up, 7 developed pressure ulcers and 20 remained free of pressure ulcers. A convenience sample of 22 normal control subjects were also enrolled.
520 $a The experimental protocol for tissue tolerance measurement was conducted on both normal and control subjects. Subjects were assessed using the following instruments: Xsensor Pressure Mapping System, the Vasamedics laser Doppler flowmeter, the Novametrix transcutaneous O2-CO2 monitor with probe maintained at 37°C, and the Braden Scale. Critically ill subjects were followed prospectively and assessed using the staging criteria developed by the Agency for Health Care Policy & Research and the National Pressure Ulcer Advisory Panel.
520 $a This study identifies general patterns of tissue response to pressure loading and unloading that are worthy of further investigation as potential adjunctive predictive tools of pressure ulcer risk in the critically ill population. Patients developing pressure ulcers were distinguished from those who remained free of pressure ulcers based on LD baseline and patterns of LD response to tissue loading and unloading. Subjects who developed pressure ulcers differed significantly from those who did not in hyperemic responses following pressure unloading. There were no significant differences between critically ill but pressure ulcer free patients and normal subjects. Poor tissue tolerance to pressure (and resultant pressure ulcers) may be associated with a failure to adequately perfuse and reperfuse, times subjected to pressure-induced ischemia.
