Aim:
The aim of this work was to investigate the pressure distribution in an innovative mattresssystem that is automatically shaped as a cradle before it slowly starts the turning process.
Method:
We have tested a system where the base is shaped as a cradle before the turning process starts. Pressure Imaging tests were performed when the test person was lying in different positions on a flat mattress (supine, 30o and 90o) over time and with the automated cradle turning (ACT) program.
Results / Discussion:
Pressure or pressure in combination with shear of the skin and underlying tissues over bony prominences is seen as the main cause of pressure ulcers (EPUAP). The amount of pressure/shear over time is a major factor for cell deformation and cell death. To reduce the time tissues are deformed, repositioning is paramount. A 30o side-lying position is recommended according to the EPUAP guidelines. However, reposition is seen as a challenge for the patient, i.e. as a disturbance, strongly affecting the sleep pattern and thus their Quality of Life. For caregivers, it is also challenging to reposition the patient in a stable, comfortable and secure 30o side-lying position. When comparing pressure images of the test person lying in a manual positioned 30o position with cushion support, with images while being rotated by the ACT system, we clearly observed better readings in the cradle system then in the manual positioned situation.
Conclusion:
The CT system had several advantages compared to manual repositioning.
