Full-body interface pressure testing as a method for performance evaluation of clinical support surfaces

Pressure Measurement at Biomedical Interfaces

“…For instance, shear contributions with pneumatic tourniquet cuffs may be reduced by using an initial inflate-deflate cycle to 'settle' the cuff onto the limb. However, even with such protocols, standardised procedures and controls, there is still significant scope for variability in results, since 'no two humans, even of the same weight and stature, are anatomically identical' (Shelton et al, 1998). This situation is likely to continue unless a completely shear independent biomedical interface pressure transducer emerges.…”

“…Along with temperature, the use of pressure as a general physiological parameter is well established and it may be accurately and reliably determined for a wide range of medical applications and environments involving liquids and gases (Mootanah & Bader, 2006). However, pressure is also commonly used in biomedical engineering and medicine to quantify the mechanical interaction between biomedical interfaces such as those arising between tissue and support surfaces (Tissue Viability Society, 2010;Shelton et al, 1998), e.g. beds, seats, prosthesis, and between tissue and pressure applying devices such as tourniquets (Doyle & Taillac, 2008), bandages (Partsch et al, 2006), and surgical instruments.…”

“…This makes it very difficult to compare values of interface pressure obtained by different research groups and has lead some groups to seek an alternative metric (e.g. statistical (Shelton et al, 1998), Limb Occlusion Pressure, LOP (Aziz, 2009;McEwen et al, 2002), deformation (Oomens et al, 2010), etc.) to reliably quantify the effects of compression on real tissue.…”

Effects of Mattress Material on Body Pressure Profiles in Different Sleeping Postures

“…Therefore, the objective of this study was to evaluate the effect of different types of bed material (latex and polyurethane foam) on the body contact pressure profiles in various sleeping postures, using peak body pressure and pressure distribution as outcome measures. 17,24,25 We hypothesized that the latex mattress would perform better in reducing the body contact pressure profiles across different sleeping profiles, compared with polyurethane foam mattress. The purpose of this study was to evaluate the performance of different mattress materials in order for hospitals to determine the type of mattress best suited for patients by reducing risk of pressure sores.…”

Comparison of evaluation methods for measuring pressure of compressionwear

“…예를 들어 화상 환자들이나 외상 수술 환자들은 수술 후 피부 조직의 빠른 회복을 돕기 위해 압박의류를 착용한 다 (Dirik et al, 2001;Engrav et al, 2010;Shelton et al, 1998;Tazelaar et al, 1999). 의료용 압박 스타킹 은 수술 환자의 부종 방지에 도움을 주고 (Hafner et al, 2000), 오랫동안 서 있는 직업의 여성들도 부종 을 방지하고 하체 혈액순환을 원활하게 하기 위하 여 압박기능이 있는 스타킹을 착용한다 (Ng & Hui, 1999).…”
