Pressure distribution analysis of X-Ray table mattresses

Area of Science:

• Medical Imaging and Radiology
• Biomedical Engineering
• Patient Safety

Background:

• Poor pressure redistribution properties of X-ray table mattresses pose a risk for developing pressure ulcers.
• Patient immobility during radiological procedures increases susceptibility to tissue damage.

Purpose of the Study:

• To evaluate and compare the pressure redistribution capabilities of new versus existing X-ray table mattresses.
• To quantify the impact of mattress age and type on pressure distribution.

Main Methods:

• Twenty-one X-ray table mattresses (2.5 cm thickness) were tested using an anthropomorphic phantom simulating adult head, pelvis, and heel positions.
• Peak pressure and Interface Pressure Ratio were measured with Xsensor technology, with and without mattresses, across a range of simulated body weights.

Main Results:

• All tested mattresses showed statistically significant differences (p < 0.05) in peak pressure and Interface Pressure Ratio compared to no mattress.
• Mattress age and type significantly influenced pressure redistribution, with older mattresses performing less effectively.

Conclusions:

• Newer X-ray table mattresses demonstrate superior pressure redistribution, likely due to advanced materials or degradation of older ones.
• Radiology departments should implement regular (e.g., annual) assessments of mattress pressure redistribution properties to ensure patient safety.
