“…Evaluation of the pressure redistribution in the air cells was performed through a hand check, as recommended by the manufacturer. It is a pragmatic/accessible measure to avoid bottoming‐out, which is a well‐defined phenomenon used to describe determination of optimal inner pressure in a support surface . A flat hand was placed under the air cells directly underneath the patient's pelvic region, in order to control a finger's thickness between the patient's body and the underlying mattress.…”

The primary objective was to study pressure ulcer (PU) category II-IV (including suspected deep tissue injury and unstageable PUs) cumulative incidence and PU incidence density, in a 30day observation period, associated with the use of the CuroCell S.A.M. PRO powered reactive air support surface in nursing home residents at risk for PU development. Secondary objectives were to study (a) PU category I cumulative incidence and PU incidence density and (b) user (caregivers and residents) experiences and perceptions of comfort associated with the use of the support surface under study. A multicentre cohort study was set up in 37 care units of 12 Belgian nursing homes. The sample consisted of 191 residents at risk of PU development (Braden score ≤ 17). The cumulative PU incidence was 4.7% (n = 9).

“…Hysteresis is defined as the phenomenon exhibited by pressure mapping systems in which the systems' reaction to changes is dependent on its immediate history [43]. This is mainly due to a delay occurring between the application and removal of a force thereby impeding the system's ability to return to its original state [44]. Creep, on the other hand, is defined as an increase in pressure with constant force, and may cause the pressure mapping system to gradually deform with constant pressure [44].…”

Introduction: Pressure ulcers present significant trauma to patients and are expensive to manage. In medical imaging (MI), no study has been conducted to rigorously investigate interface pressure (IP) risk on MI table surfaces. IP is defined as the pressure between human body and a supporting surface. The aims of this research were to investigate whether IP risks exist on MI table surfaces and to assess pain and comfort when lying on MI table surfaces. Methods: A calibrated XSENSOR mat was used to measure IP for three jeopardy areas (head, sacrum, and heels) in healthy volunteers on an x-ray table surface with no mattress, an x-ray table surface with a thin radiolucent mattress, and a computed tomography table surface, after which they completed a pain and comfort questionnaire. Results: The sample consisted of 26 females and 23 males aged 18-59 years (mean ¼ 34.6; standard deviation [SD] ¼ 10.5). Analysis of variance identified statistically significant differences in the mean IP for the jeopardy areas across the three MI table surfaces (P .001). Results also indicated high mean IP value for the head (75.9 mmHg; SD ¼ 6.9) on the x-ray table with no mattress. Seventy percent of the volunteers found lying on the x-ray table with no mattress to be very uncomfortable. Sixty-seven percent experienced most pain whilst lying on the x-ray table with no mattress and over 81% of the pain occurred at the head. Conclusion: IP risk exists on x-ray tables with no mattress. This could increase the risk of developing pressure ulcers in patients accessing prolonged radiography/radiology procedures.

“…Sanada et al 3 used a cell‐type pressure‐switching mattress to conduct a quasi‐experimental study on the relationship between the mattress internal air pressure and maximum interface pressure in the supine and lateral positions in healthy individuals. Sasaki et al 4 also evaluated the relationship between a prototype air mattress's internal pressure and interface pressure. Based on the measurement of the sacral interface pressure, they reported that the interface pressure is high when the internal air pressure is either high or low, with the interface pressure vs the internal air pressure plot forming a U curve.…”

Previous research shows that maximum interface pressure increases when the patient is lying in the lateral position. However, it was unclear whether it was better to increase or decrease the internal air pressure to reduce the maximum interface pressure in the lateral position; thus, this study investigated this issue. In this study, we investigated the change in pressure redistribution because of the difference in internal air pressure between the supine and lateral positions on an active air mattress for pressure ulcer prevention management. Each participant's five internal air pressure values served as the independent variables. The interface pressure on the active air mattress was measured for 20 minutes. The sacral left iliac crest and left greater trochanteric interface pressures were measured using a portable pressure-measuring device. When seven of the 10 participants switched from the supine position to the left lateral position, there was a decrease in the maximum interface pressure as the internal air pressure increased. The maximum interface pressure in the greater trochanter in the lateral position was twice that in the sacral region in the supine position. These results show that increasing the internal air pressure in the lateral position might help reduce the maximum interface pressure.active air mattress, interface pressure distribution, lateral position, mattress internal air pressure, pressure ulcer prevention Key Messages• this study evaluated the relationship between mattress internal air pressure and interface pressure redistribution in the lateral position to prevent pressure ulcers • the interface pressure was measured using a portable device with 10 healthy participants • when changing from the supine to lateral position, the maximum interface pressure may be suppressed by increasing the mattress internal air pressure
