Abstract: Diabetic foot is one of the most serious and painful chronic complications of diabetic patients, especially for elderly, and is associated with high mortality, disability and amputation rate. Obstructive sleep apnea (OSA) is a treatable chronic sleep disorder.  Available evidence suggests that OSA has the effect of promoting diabetic foot development and delaying wound healing, while continuous positive airway pressure therapy may promote ulcer healing. Therefore, in the model of multidisciplinary diagnosis and treatment of diabetic foot, to strengthen the cooperation with the specialists of sleep medicine and to promote the basic and clinical research of diabetic foot combined with OSA, may decrease the amputation rate, improve wound healing rate and reduce cardiovascular events.

Key words: diabetic foot, sleep apnea, , obstructive, diagnosis, treatment
