How much tilt and recline do you need in order to achieve adequate, clinically-effective pressure relief? Tilt and recline, when used appropriately, can be very effective at redistributing pressure. Pressure redistribution is key for preventing and treating pressure injuries.
The greatest reductions in pressure are seen when both techniques are used together, either at tilt of 35° with recline 100° or tilt of 15-25° with recline of 120°. Tilt, when used alone, must be greater than about 25° to achieve pressure relief and/or tissue perfusion at the ischial tuberosities. Recline, when used alone, can increase shear but may reduce pressure at the ischial tuberosities at angles greater than 90-100°.
