Abstract：Objective To explore the application of local oxygen therapy in the skin care of elderly patients with renal failure who have been bedridden for a long time using alternating decompression air mattresses.Methods A total of 70 elderly patients with renal failure who were bedridden for a long time in The First Affiliated Hospital of Xi'an Jiaotong University from February 2023 to March 2025 were selected as the research subjects.According to the random number table method,they were divided into the control group(receiving conventional care combined with alternating decompression air mattresses)and the study group(adding local oxygen therapy on the basis of the control group),with 35 cases in each group.The incidence of pressure ulcers,the status of pressure ulcers,the incidence of adverse events,and the satisfaction of nursing were observed.Results There was no statistically significant difference in the incidence of stage I,stage II,and stage III pressure ulcers between the control group and the study group(P>0.05).The incidence of pressure ulcers in the study group was lower than that in the control group(P<0.05).The Braden Scale scores of the study group at 1,3,and 7 d of intervention were all higher than those of the control group(P<0.05).There was no statistically significant difference in the incidence of adverse events such as infection and skin allergy between the control group and the study group(P>0.05).The nursing satisfaction of the patients in the study group was significantly higher than that in the control group(P<0.05).Conclusion Local oxygen therapy combined with alternating decompression air mattresses can effectively reduce the incidence of pressure ulcers in elderly patients with renal failure who have been bedridden for a long time and improve the Braden Scale score,and the nursing satisfaction of patients and their families is relatively high.It is a safe and effective comprehensive nursing plan and is worthy of clinical promotion and application.
