The Relationship Between Driving Pressure, Mechanical Power, Oxygenation and Saturation Indices: Retrospective Observational Study
An observational study of Acute Respiratory Distress Syndrome and Pneumonia, run by Bakirkoy Dr. Sadi Konuk Research and Training Hospital at 1 site in Turkey (Türkiye).
Trial summary
By using Mechanical Power and Driving Pressure instead of Pmean we calculate new oxygen saturation indices like Driving Pressure Oxygen Index (OIDP), Dynamic Power Oxygen Index (OIMPdyn), Total Power Oxygen Index (OIMPtot), Driving Pressure Saturation Index (OSIDP), Dynamic Power Saturation Index (OSIMPdyn) ve Power… Read more about this study

Study population: The data of 784 patients with a diagnosis of Covid-19 hospitalized in the 28-bed intensive care unit of the Bakirkoy Dr. Sadi Konuk Training and Research Hospital were obtained by using structured query language (sql) queries from the 'ImdSoft-Metavision/QlinICU Clinical Decision Support (Israel) system'.173 patients who did not receive invasive mechanical ventilation support, 64 patients who stayed in the intensive care unit for less than 24 hours, 40 patients with missing data, and 38 patients who received mechanical ventilation support for less than 24 hours were excluded from the study.24 patients with COPD, 27 patients with congestive heart failure, and 11 patients who underwent tube thoracostomy due to tension pneumothorax were excluded from the study.In addition, 46 patients who received ECMO support were excluded from the study due to the possibility that ECMO may have an effect on respiratory variables. The remaining 361 patients were included in the study.
Who may be able to join
- Patients with a diagnosis of Covid-19 related Acute Respiratory Syndrome (C-ARDS) which hospitalized in Bakirköy Dr. Sadi Konuk Training and Research Hospital intensive care unit
Who cannot join
- Patients who did not receive invasive mechanical ventilation support.

About this study
By using Mechanical Power and Driving Pressure instead of Pmean we calculate new oxygen saturation indices like Driving Pressure Oxygen Index (OIDP), Dynamic Power Oxygen Index (OIMPdyn), Total Power Oxygen Index (OIMPtot), Driving Pressure Saturation Index (OSIDP), Dynamic Power Saturation Index (OSIMPdyn) ve Power Saturation Index (OSIMPtot).
New oxygenation and saturation indices are able to predict ICU mortality better than the conventional indexes and rates.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
By using Mechanical Power and Driving Pressure instead of Pmean we calculate new oxygen saturation indices like Driving Pressure Oxygen Index (OIDP), Dynamic Power Oxygen Index (OIMPdyn), Total Power Oxygen Index (OIMPtot), Driving Pressure Saturation Index (OSIDP), Dynamic Power Saturation Index (OSIMPdyn) ve Power Saturation Index (OSIMPtot).
New oxygenation and saturation indices are able to predict ICU mortality better than the conventional indexes and rates.

Questions about this trial
What is this clinical trial studying?
An observational study of Acute Respiratory Distress Syndrome and Pneumonia, run by Bakirkoy Dr. Sadi Konuk Research and Training Hospital at 1 site in Turkey (Türkiye).
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 8 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: finished, as of the sponsor's last update on 10 Jan 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 Turkey (Türkiye). 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?
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?
In hospital mortality (time frame: 28 days). 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 10 Jan 2023; AzTrials last refreshed its copy on 6 Nov 2026.
