Being bedridden causes a series of complications related to immobilization, such as pressure ulcer, lung infections, deep venous thrombosis of the lower extremities, and urinary tract infections. These complications can lead to many harmful consequences, which not only have many adverse effects on the prognosis and life quality of the patients, but also lay enormous economic and mental burden on the family and society. Therefore, the prevention of complications in bedridden patients is essential for the clinical work. At present, the clinical prevention of complications is mainly through early exercises, enhanced nursing and other measures, whose effect is not optimistic. Therefore, how to take effective measures to reduce the incidences of bedridden complications and reduce their susceptibility factors is particularly important.
