Experience Summary

In this 360-degree video, observe staff explain the process of, and perform a 30° tilt, with some aid from the patient.

Clinical Context

Correct bed positioning is a fundamental aspect of pressure ulcer prevention in healthcare settings. Pressure ulcers, also known as pressure sores or bedsores, are localised injuries to the skin and underlying tissues caused by prolonged pressure, often over bony prominences such as the sacrum, heels, hips, and elbows. Immobile patients, especially those who are elderly, critically ill, or recovering from surgery, are particularly vulnerable. Effective bed positioning helps redistribute pressure, improve circulation, and reduce the risk of skin breakdown.

One of the most effective and widely recommended techniques in pressure ulcer prevention is the 30-degree tilt. This method involves positioning the patient so that they are lying on their side, but tilted back at a 30-degree angle from the horizontal. This semi-side-lying position helps to relieve direct pressure from high-risk areas such as the sacrum, trochanters (hips), and heels, while maintaining a comfortable and sustainable posture for the patient.

The 30° tilt reduces the force of pressure and shear—two key factors in ulcer development. When a patient lies directly on their side (90°), there is high pressure on the greater trochanter, and when lying flat on the back (supine), the sacrum is at risk. By using the 30° position, the weight is more evenly distributed, decreasing the likelihood of tissue damage. This position is also easier to maintain and often more comfortable than more extreme angles, improving patient compliance.

Bed positioning should be changed at least every two hours for high-risk patients, or as directed by individual care plans. Alternating between the 30° tilt on the left and right sides, combined with occasional supine positioning when appropriate, forms a key part of a regular repositioning schedule.

Proper support with pillows or wedges is essential to maintain the 30° angle and prevent the patient from rolling into a harmful position. Pressure-relieving mattresses and cushions should also be used in conjunction with repositioning to further reduce risk.
