About this study
Official title: A Descriptive Analysis of Diving Accidents Treated at the Hyperbaric Chamber of Nice University Hospital Between 2014 and 2025
The study aims to describe and analyse the individual parameters of patients treated at the hyperbaric chamber of Nice University Hospital for suspected diving accidents. This analysis will, in particular, enable an examination of any correlations between certain health parameters and the occurrence of desaturation accidents, despite adherence to the decompression procedure indicated by the dive computer.

Questions about this trial
What is this clinical trial studying?
An observational study of Decompression Sickness and Diving, run by Centre Hospitalier Universitaire de Nice.
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.

The record says: finished, as of the sponsor's last update on 2 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Diving accident (time frame: At the inclusion). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 2 Jun 2026.
