Hypoxic Respiratory Failure Clinical Trial
Official title:
Clinical Study of Diaphragmatic Ultrasound to Predict the Therapeutic Effect of High Flow Oxygen Therapy in Mild and Moderate Acute Hypoxic Respiratory Failure
Follow-up was conducted for every patient requiring high-flow nasal cannula oxygen therapy in district 1 of the Intensive Care Department of Chenzhou NO.1 People's Hospital. Patients who met the inclusion criteria but did not meet the exclusion criteria were included for observation. Respiratory parameters, diaphragmatic activity, and variation rate of diaphragmatic thickness were recorded at the beginning of high-flow nasal cannula oxygen therapy, 1 hour after treatment, 3 hours after treatment, 6 hours after treatment, 9 hours after treatment, and 12 hours after treatment. Throughout the procedure, a panel of experts assessed whether the patient needed endotracheal intubation; If yes, the study was terminated; if no, high-flow nasal cannula oxygen therapy was continued, and observation and evaluation were continued until the end point of the study (12 hours after treatment). If patients or their family members do not want to continue to participate in the study during the study, they will be considered as withdrawal. If patients suffer from sudden malignant arrhythmia or cardiac arrest during the study, resulting in death or transfer to other hospitals or other departments during the study, patients will be excluded. Data from dropped and excluded patients were not included in the final statistical analysis. After the data of 269 patients were collected, the study was concluded, and the results and conclusions were derived by statistical analysis.
