Abstract:
Objective To explore the feasibility of oxygen saturation related diffusion index for assessing oxygenation status,and to establish the critical value of the oxygen saturation related diffusion index,so as to provide more approaches to monitoring oxygenation status.Methods A total of 30 patients with acute respiratory distress syndrome (ARDS) receiving mechanical ventilation support were retrospectively reviewed.Totally 340 cases were collected at corresponding time points,and were divided into mild,moderate and severe groups according to ARDS Berlin criteria.Results There was a positive correlation between oxygen saturation related diffusion index and oxygenation index (r=0.698,P＜0.001);the critical value between the moderate and severe groups of oxygen saturation related diffusion index was 171(sensitivity 84.7％,specificity 68.2％),and the critical value between mild group and moderate group was 440 (sensitivity 56.9％,specificity 91.9％).Conclusion The oxygenation index was consistent with the oxygen saturation related diffusion index in judging the oxygenation status of ARDS patients.As a noninvasive and continuous index,the oxygen saturation related diffusion index provides a new method for nursing assessment.
