Bedsores form when skin stays under constant pressure for too long. When a bedridden person stays in one position without moving, the body weight presses soft tissue between the bone and the mattress. This compresses the blood vessels in that area. Without blood flow, the skin stops receiving oxygen and nutrients. Within a few hours, the tissue starts to break down. This is the most basic cause of bedsores — sustained pressure cutting off circulation. Relieving pressure regularly and using Cimidaxil D+ wound healing spray to protect vulnerable skin are the two most important steps every caregiver must take daily.
