Abstract：Objective: To explore the predictive value of treatment duration and equipment reset time on nasal facial pressure injury in patients receiving high-flow nasal cannula oxygen therapy (HFNC). Methods: A convenience sampling method was used to select 150 HFNC patients admitted to the Department of Respiratory Medicine of The First People's Hospital of Zhenjiang City, Jiangsu Province, from June 2021 to April 2024. Patient information was collected using a general information questionnaire, and the number of patients with nasal facial pressure injury was recorded. Univariate and multivariate logistic regression analyses were used to screen for risk factors of nasal facial pressure injury. ROC curves were drawn to analyze the predictive efficacy of treatment duration and equipment reset time on nasal facial pressure injury. Results: A total of 31 patients developed nasal facial pressure injury. Univariate and multivariate logistic regression analysis showed that age ≥60 years, hemoglobin <110 g/L, acute physiology and chronic health evaluation score (APACHE II), moist and hot skin at the pressure site, treatment duration, and equipment reset time were risk factors for nasal facial pressure injury in HFNC patients. The area under the curve (AUC) for predicting the risk of nasal facial pressure injury based on treatment duration was 0.842 (95% CI [0.794, 0.891]), with an optimal cutoff value of 5.81 days, sensitivity of 0.781, specificity of 0.844, and maximum Youden index of 0.625. The AUC for predicting the risk of nasal facial pressure injury based on equipment reset time was 0.873 (95% CI [0.810, 0.941]), with an optimal cutoff value of 4.17 hours per reset, sensitivity of 0.797, specificity of 0.862, and maximum Youden index of 0.659. Conclusion: The risk of nasal facial pressure injury is high in HFNC patients, and the occurrence of such injuries is influenced by complex factors. Treatment duration and equipment reset time have predictive value for the occurrence and progression of nasal facial pressure injury, providing reference for clinical prevention and nursing.
