简要总结
This study intends to use ultrasound to measure the bilateral diaphragmatic ultrasound indicators in critically ill patients, focusing on the left diaphragm, and to explore the consistency and reliability among various ultrasound indicators to evaluate the diaphragmatic mobility

入选标准
- •①Adult patients (≥18 years old) of both sexes;
- •In invasive group, intubation or tracheotomy was changed to 5L/min T-tube or tracheotomy mask oxygen inhalation;
- •Patients in non-invasive group were treated with mask oxygen 5L/min;
- •agree to participate in the trial and sign the informed consent;
排除标准
- •①The diaphragm ultrasound operation site was too large to obtain images.
- •Diaphragmatic ultrasound images could not be obtained in any section;
- •The ultrasound image quality of any section was poor;
- •the presence of phrenic nerve injury/paralysis ⑤ pregnant women; ⑥ Neuromuscular diseases such as ALS and myasthenia gravis affect the evaluation of spontaneous breathing ⑦ Patients deemed by the investigator to be ineligible.
研究组 & 干预措施
Invasive respiratory support group
The subjects of ultrasound measurement were patients with invasive mechanical ventilation
Noninvasive respiratory support group
The subjects of ultrasound measurement were patients with non-invasive respiratory support
结局指标
主要结局
Consistency of diaphragmatic mobility measurements between the standard and modified positions on the left side.
时间窗: Measurements were performed 5 minutes after all patients were switched to conventional oxygen therapy at 5 L/min for the first time, once breathing had stabilized.
The main purpose is to verify the consistency of the two methods, Measurements were performed after switching patients in the invasive group (intubated patients to T-piece oxygen at 5 L/min and tracheostomized patients to face mask oxygen at 5 L/min following weaning), and patients in the non-invasive group (those receiving non-invasive ventilation or high-flow oxygen therapy) to conventional face mask oxygen at 5 L/min.
次要结局
- Consistency of diaphragmatic excursion measurements between the standard position and the other four positions on the left side.(Measurements were performed 5 minutes after all patients were switched to conventional oxygen therapy at 5 L/min for the first time, once breathing had stabilized.)
- Consistency of diaphragmatic excursion measurements between the standard position and the other five positions on the right side.(Measurements were performed 5 minutes after all patients were switched to conventional oxygen therapy at 5 L/min for the first time, once breathing had stabilized.)
