  • Cleaning a pressure sore: Pressure sores need to be kept clean and free from dead tissue. A saline solution can be used and a dressing applied. The dressing should be renewed daily unless it is a specialized dressing product, such as a hydrocolloid dressing, or a film dressing. Your doctor or health care advisor will instruct you on the appropriate length of time.
    Medical advice and intervention is advised to help in the assessment and treatment of pressure sores.
