In which position should pillows be used to prevent unilateral pressure?

Using pillows in a side-lying position is beneficial for preventing unilateral pressure, particularly in patients who may be at risk for pressure injuries, such as those with limited mobility or sensation. When a person is lying on their side, placing pillows strategically helps to redistribute weight and relieve pressure points that can occur at bony prominences, such as the hips, shoulders, and ankles.

In the side-lying position, pillows can be placed between the knees to prevent leg compression, under the head for neck support, and along the back to provide additional stability. This positioning technique not only enhances comfort but also promotes better circulation by alleviating sustained pressure on any one side of the body.

Other positions such as supine, sitting, and prone may not effectively address unilateral pressure issues as well as the side-lying position can. For example, in the supine position, pressure can still build up on the back and heels. In a sitting position, the weight is concentrated on the buttocks and thighs, potentially leading to pressure sores in those areas. Prone positioning does not typically allow for easy alleviation of pressure from bony prominence areas, making it less suitable for this purpose. Therefore, the use of pillows in the side-lying position is a key
