|Median||85.3 mmHg||52.3 mmHg|
*These results are from a preliminary pressure mapping study that explored the influence of bed linen layers on interface pressure. High pressure over the sacral-coccygeal area was recorded when the person was moved into high Fowler’s position. The procedure was repeated 15 times with different bed linen layers.
