The nurse call systems use a button that is often available around the hospital bed to give the patient a remote way of communication (alert or buzz) to be able to call the nurses’ station when in need of help. These systems are very important in a hospital as they give the patients a sense of security, as well as providing them with a better way to communicate with the staff if they are not able to move out of their bed, furthermore, providing the hospital with a quicker way to serve the patients in need, as this system can be integrated to different mobile devices that can be used around the hospital.
