Objective

Verify if the inflation pressure of anti-bedsore air cushions in persons with bone marrow injury is optimum and determine its influence on the mechanical behavior of the cushions.

Material and methods

The distribution of the user-cushion inferface was analyzed with a capacitive mesh sensor in 32 subjects with bone marrow injury who used air cushions. A recording was made of the usual conditions of inflated pressure and another one after making a correction of it once identified the optimum pressure distribution situation. Parameters analyzed were maximum pressure value (Pmax), ischiatic pressure (IschP), mean pressure (meanP) and standard deviation (SD) and, in regards to surfaces, total surface (totS), surface that supports a pressure of 60 mmHg (totS>60) and percentile value (%totS>60).

Results

The values of the variables related with the pressure were lower in the recordings made after correcting for inflated pressure. In those related with surface, the TotS was higher in the second recording while the totS >60 and%totS>60 were lower. There were significant differences in all of the cases (p<0.05).

Conclusion

The different inflation pressure of an air cushion influences the pressure distribution of the user-cushion interface. The distribution of the optimum pressures for a certain cushion is achieved at an inflated pressure level that must be established with some objective measurement systems.
