Abstract:
1. Large-celled alternating pressure mattresses are more effective than small-celled mattresses in preventing pressure necrosis. 2. Mattresses must be sufficiently robust not to break down in use. 3. Clinical trials are often faulty and therefore need to be read carefully. 4. Control regimens must be fully described.
