Dynamic devices are generally noisy and more expensive than static devices. Dynamic surfaces should be
considered if a patient cannot reposition him or herself independently or if the patient has a poorly healing ulcer. If there is less than 1 inch of material between the bed and a pressure ulcer when feeling beneath the static surface, the device may not be effective and an alternative should be considered.[18] Ring cushions can cause a pressure ulcer and should not be used.
The fourth line of action is provision of accessible and adequate support. Patient may need more intensive
support services, or care givers may need more intensive support services or care givers may need more training or assistance with lifting and turning the patient. Patients with communication or sensory disorders are particularly vulnerable to pressure ulcers because they may not feel discomfort or may express discomfort in a typical way.
The fifth action is improving mobility. For patients who cannot move themselves or who have difficulty
moving themselves: Reposition them. The schedule the nurse devises should be based on the patient’s level of risk as well as other factors such as the presence of lay caregivers and the availability of pressure redistribution devices. Repositioning the patient is not always easy. The nurse must remember to take into account the comfort level of patients who are put into positions they do not normally assume. She needs to ensure that she is not putting the patient into a position that will put pressure on another body part. She must make sure you use proper repositioning techniques and body mechanics to ensure that both you and the patient are not injured during the process. She also needs to ensure pain management is part of the turning schedule. Some patients can reduce pressure by repositioning themselves using manual aids such as trapeze bar. Position of the patient should be changed as scheduled when the patient is in bed.
