Abstract：[Objective]To explore the characteristics of pressure ulcer in ICU and the correlation of the oc-currence with oxygenation with perfusion index.[Methods]Totally 1 1 3 patients in ICU were divided into pressure ulcer group(n=26)and non-pressure ulcer group(n=87).General information on admission,oxy-genation and perfusion index between two groups were compared.Meaningful indicators were taken for further logistic regression analysis to identify the correlation.[Results]Multiple sites of pressure ulcer were sacrococ-cygeal region,hip and scapular.Most patients with pressure ulcer were divided into stageⅠ and Ⅱ.The av-erage age and the proportion of hospital admission diagnosis of respiratory disease and trauma in pressure ulcer group were obviously higher than those in non-pressure ulcer group(P<0.05).There were significant differ-ence in pH,PaCO2 ,SBP,DBP,MAP and Braden score between two groups(P<0.05).Multivariate analy-sis showed that the advanced age(β= 1.637,OR= 5.140),respiratory diseases(β=1.592,OR=4.914)and trauma(β=1.748,OR=5.743)were risk factors for the occurrence of pressure ulcer in ICU patients,while high MAP(β=-1.528,OR=0.217),high Braden score (β= -1.705,OR=0.182)were protective factors.[Conclusion]The advanced age,respiratory diseases and trauma are risk factors for the occurrence of pressure ulcer in ICU patients,while high MAP and high Braden score are protective factors.
