Ultrasound Examination of the Diaphragm as a Predictor of Successful Ventilator Weaning of Patients

Abstract

The relevance of the survey is linked with the persistent problem of weaning patients who have been on mechanical ventilation for a long time. The objective. To conduct a literature analysis in order to summarize the results of modern researches devoted to the study of sonographic parameters that allow estimation of diaphragmatic functions for predicting successful weaning of patients from artificial lung ventilation. Material and methods. In total 33 Russian-language and English-language sources were analyzed. Results. The following ultrasound parameters of the diaphragm were analyzed in detail: diaphragm excursion, diaphragm thickening fraction, diaphragmatic rapid shallow breathing index, and the time to peak inspiratory amplitude of the diaphragm. Conclusions. The ability to timely diagnose diaphragm dysfunction using ultrasound minimizes the risk of respiratory and cardiac failure. Currently there are methods of the diaphragm muscle stimulation to improve the recovery of lost functions.
