Abstract
The purpose of this study was to clarify which of the two methods of folding the upper side of the sheet into a triangle (triangle method) and tying both upper sides of the sheet (tying method) is less likely to cause sheet slippage as a bed-making method for air mattresses. Forty-one nursing students conducted bed-making on air mattresses using the two methods, and daily living assistance was given to simulated patients on the beds to compare sheet slippage.
The triangle method was resistant to sheet slippage for the air mattress overall, the center, foot side, right side, left side, and surface. It was only on the head side that the tying method was more resistant to sheet slippage. The triangle method is considered to be more resistant to sheet slippage than the tying method because the contact area between the sheets is large and the frictional force is large. In particular, the triangle method is considered to lead to a reduction in the risk of bedsores, since the central and foot side where the sacral region and calcaneus area, which are frequent sites for bedsores, are located are less prone to sheet slippage.
