Plain-language summary
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

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* 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;
Exclusion Criteria:
* 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.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Consistency of diaphragmatic mobility measurements between the standard and modified positions on the left side.
Timeframe: 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.
