Study on the Measurement Method of the Left Diaphragm (LD)
2026年4月23日 更新者：Shanghai Zhongshan Hospital
To Study the Consistency of Multiple Measurement Methods of Left Diaphragm Mobility in Critically Ill Patients
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

メジャーの説明 |
時間枠 |
|---|---|---|
|
Consistency of diaphragmatic mobility measurements between the standard and modified positions on the left side.
時間枠：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.

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.
