Typically the head of a hospital bed has a control panel which allows hospital staff to make adjustments to the bed. Patients can also use the control panel to do things like call a nurse in the event of an emergency. The bed may also have poles for the purpose of hanging bags of intravenous fluids, and it may include drawers to store various tools needed for procedures. There is also a space at the foot of the medicle beds for the patient's chart.
As you might imagine, most hospital beds require electricity to run the adjustment mechanisms and control panels, although some older beds can also be cranked by hand into various positions. Some hospital beds come with sophisticated computer systems which can be used to do things like save bed settings which are comfortable for the patient or necessary for procedures. Learning to use these systems can take time, and hospital staff usually discourage patients and friends from adjusting the bed themselves.
Medicle bed also typically have rails, which are designed to prevent patients from rolling out. These rails can be raised and lowered to perform procedures or to make patients feel more comfortable. Lowering the rails also allows hospital staff to transfer patients from beds to gurneys, such as those used to transport patients to the operating room for procedures. Many hospital beds are also movable so that patients can be relocated with minimal disturbance.
