All are abuse, sometime the patients bump themselves. Pay close attention to where the injuries are and if the patient could do it to themselves. It's sort of like 42 stab wounds in the back and the coroner rules it a suicide. Bruising and skin tears are usually a sign of rough handling of the patients and this needs to be reported. How many air beds are in the facility.
Air beds are easy to recognize.
Many make a hissing sound, most have much thicker mattresses than normal, many of them have a 2 foot by 2 foot box attached at the foot of the bed. Air beds are very expensive. Bedsores indicate the patient has been left laying in their own waste for long periods of time and or their nutrition is bad. Once a bedsore is discovered, BY LAW, that patient is to be turned or repositioned every 2 hours. If there is more than 2 air beds in the facility, that is a huge red flag the facility is not changing or feeding properly.
