Summary

There are two cases in which the cross-sectional area of the tracheal catheter balloon does not match the cross-sectional area of the patient's airway. If the area of the tracheal catheter balloon is smaller than the cross-sectional area of the patient's airway, the pressure in the balloon reaches 30 cmH2O, and the airway cannot be completely sealed; This will increase the risk of VAP. If the area of the tracheal catheter balloon is significantly larger than the cross-sectional area of the patient's airway, and the pressure in the balloon reaches 30 cmH2O, the airway cannot be effectively sealed; The formation of wrinkles around the airbag also increases the risk of VAP in patients. Therefore, the purpose of this study is to build a risk model of airway leakage of patients' endotracheal tubes, which provides an accurate and objective assessment tool for medical staff, so that medical staff can select the endotracheal tubes purposefully and with emphasis from the beginning of the patients' endotracheal tubes, and reduce the airway leakage or airway mucosal damage of the endotracheal tubes.

Construction and evaluation of airway leakage risk model of patients with endotracheal tube

1. Conduct statistical analysis on general information, respiratory data, tracheal catheter data, and cross-sectional area of the patient's airway to clarify the current status of airway leakage and related influencing factors. 2. Based on multivariate logistic regression, a line chart prediction model for predicting the risk of airway leakage in patients with tracheal catheters is constructed. The clinical efficacy of the prediction model is evaluated by using the area under the ROC curve, the Calibration scatter plot, and the DCA decision line, respectively, to assess its discrimination, calibration, and clinical practicality.
