“…However, an interaction between multiple variables most likely explains why a pressure ulcer develops in some patients but not in other patients at risk. 1,18,20 The variables we examined were significantly associated with the development of pressure ulcers, and 4 variables were significant predictors in both regression models.…”

“…In 2 studies, 12,13 oxygen and perfusion variables were examined as risk factors for pressure ulcers. However as Defloor 1 noted, a conceptual scheme for risk for pressure ulcers is needed to understand how these risk factors interact. Early intervention is required for patients at increased risk for pressure ulcers, yet more research is needed to better identify risk 19 to provide early intervention and validate the costs of preventive therapies, such as use of specialty beds, equipment, and turn teams.…”

This article has been designated for CE contact hour(s). The evaluation tests your knowledge of the following objectives: Background Although most intensive care patients are at risk for pressure ulcers, not all experience such ulcers.Objective To examine a model of variables related to extrinsic and intrinsic pressure on skin and underlying tissues, oxygenation, perfusion, and baseline comorbid conditions to identify risk factors associated with pressure ulcers in critically ill adults. Method A retrospective chart review was conducted on patients identified by weekly rounds from January 2010 through October 2010 to determine the prevalence of pressure ulcers. Variables were analyzed via bivariate analysis and logistic regression for unit-acquired pressure ulcers. Results Data on 345 patients with 436 intensive care admissions were reviewed. Variables were significant in each model category at P < .05. In the regression analysis of first admission only (n = 306), the model was significant (P < .001) and yielded correct classification of 86.3% of patients. For all intensive care admissions (n = 391), the model was significant (P < .001) and yielded correct classification of 83.9% of patients. In both models, 4 of the same variables were significant: any transport off the unit, number of days to bed change, systolic blood pressure less than 90 mm Hg, and use of more than 1 vasopressor. History of pulmonary disease and presence of a feeding tube were also significant in regression analyses. Conclusions Several variables within the model of pressure, oxygenation, and perfusion were significantly associated with development of pressure ulcers.

“…Other theories for the onset of tissue damage include collapse of capillaries and lymph nodes [29][30][31], reperfusion injury [32][33][34], and cell deformation under pressure [5,33,35]. The last has been studied using finite element (FE) models with a damage threshold law derived from previous experiments [4,36].…”

Abstract-This study assessed the suitability of a new portable system that is based on Hertz's contact theory for evaluating internal gluteal muscle stresses under the ischial tuberosities of wheelchair users in real-time as a risk indicator for a deep tissue injury. Sitting in a wheelchair was monitored and processed with the portable system for six control subjects and five individuals with paraplegia. We compared the resultant internal peak and average muscle stresses and stress integrals over time (stress doses) of the control subjects with those of the subjects with paraplegia and validated the results against previously published subject-specific finite element (FE) stress data for the same subjects. Individuals with paraplegia were characterized by peak muscle compression stresses (mean +/-standard deviation = 109 +/-41 kPa) that were 2.4-fold higher than in control subjects (p < 0.03). A Bland-Altman comparison indicated that stresses recorded by the present system were in satisfactory agreement with previous subject-specific magnetic resonance imaging-FE analyses. We conclude that the present stress monitoring system has the potential to be a practical means for evaluating internal muscle stresses during everyday life of individuals with paraplegia.

Abstract-The demand for ubiquitous healthcare monitoring has been increasingly raised for prevention of lifestyle-related diseases, acute life support or chronic therapies for inpatients and/or outpatients having chronic disorder and home medical care. From these view points, we developed a non-conscious healthcare monitoring system without any attachment of biological sensors and operations of devices, and an ambulatory postural changes and activities monitoring system. Furthermore in this study, in order to investigate those applicability to the ubiquitous healthcare monitoring, we have developed a new healthcare monitoring system combined with the non-conscious and the ambulatory measurements developed by us. In patients with chronic cardiovascular disease or stroke, the daily health conditions such as pulse, respiration, activities and so on, could be continuously measured in the hospital, the rehabilitation room and subject's own home, using the present system. The results demonstrated that the system appears useful for the ubiquitous healthcare monitoring not only at medical facility, but also during daily living at home.
