Pressure sores, often known as bedsores, are common in patients who are bed- or wheelchair-bound. A bedsore occurs when the skin presses against something which limits the blood flow to the skin. This pressure doesn't even have to be very much; it just has to lessen the blood flow to that part of the body. This kind of pressure typically happens in places which are not well-padded, such as an elbow, the shoulder blades or the tailbone, but it can occur on any place on the body.
When it is time to consider a move to a nursing home either for yourself or for a loved one, think about each facility that interests you in terms of security. This is not just a matter of knowing whether there are proper locks on doors and windows; proper security refers to various kinds of safety matters.
