About this study
Official title: Determine the Effects of Prone Positioning and Nitric Oxide in Adult COVID-19 Patients With ARDS by Electrical Impedance Tomography
We aims to investigate the effects of prone positioning and nitric oxide inhalation in adult patients who is diagnosed with COVID-19 associated acute respiratory distress syndrome by electrical impedance tomography.
Read the detailed description
The investigators aim to investigate the effects of prone positioning and nitric oxide inhalation in adult patients who is diagnosed with COVID-19 associated acute respiratory distress syndrome by electrical impedance tomography (EIT).
The EIT assessment is performed in patients ventilated in supine position, supine position with NO inhalation for 1 hour, prone position for 1 hour, prone position for 2 hours with NO inhalation for 1 hour, prone position for 3 hours, prone position for 16 hours, re-supine position for 3 hours. Arterial blood gas (ABG) analysis results, ventilator parameters and hemodynamic parameters are also recorded at each time point.

Questions about this trial
What is this clinical trial studying?
An observational study of Respiratory Distress Syndrome, Adult and COVID-19, run by Shanghai Zhongshan Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 8 Feb 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Ming Zhong, PhD (021-65642662, zhong.ming@zs-hospital.sh.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
oxygenation status (time frame: 1 day). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05715762, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Feb 2023; AzTrials last refreshed its copy on 7 Nov 2026.
