About this study
Official title: Comparison of Oxygenation Index and Oxygen Stretch Index With Mechanical Power, Driving Pressure, Transpulmonary Pressure, and Lung Ultrasound Scores in PARDS Patients
Pediatric acute respiratory distress syndrome (pARDS) is a heterogeneous clinical syndrome that causes high rates of mortality and morbidity. The Pediatric Acute Lung Injury Consensus Conference (PALICC) guideline recommends using the oxygenation index (OI = mean airway pressure (MAP) × FiO2 /PaO2) for the diagnosis and classification of pediatric ARDS. Driving pressure (DP) is calculated by subtracting PEEP from plateau pressure. It is an important determinant of tidal volume in each breath and indirectly reflects lung stress.
It is the best parameter associated with mortality and lung injury in many studies. In the oxygenation index formula; adding driving pressure instead of Pmean may be more useful in evaluating the severity of pARDS. In our study, we will compare the Oxygenation Stress Index with OI in patients with pARDS. We will compare transpulmonary pressure, mechanical power, lung ultrasound score, and other respiratory mechanics, which are parameters indicating lung injury.
Read the detailed description
Pediatric acute respiratory distress syndrome (pARDS) is a heterogeneous clinical syndrome that causes high rates of mortality and morbidity. The Pediatric Acute Lung Injury Consensus Conference (PALICC) guideline recommends using the oxygenation index (OI = mean airway pressure (MAP) × FiO2 /PaO2) for the diagnosis and classification of pediatric ARDS. In recent years, studies conducted on adult and pediatric populations have emphasized ''driving pressure'' as the most important ventilator parameter associated with mortality. Driving pressure (DP) is calculated by subtracting PEEP from plateau pressure. It is an important determinant of tidal volume in each breath and indirectly reflects lung stress. Lung stress is directly measured with transpulmonary pressure (PL).
Mechanical power (MP) is the amount of energy applied to patients per unit time and its relationship with lung injury has been shown in adult and pediatric studies. Another method that shows lung damage is measured noninvasively at the patient's bedside. It has been validated in many adult, pediatric, and neonatal studies. In an adult study, DP was used instead of MAP inspired by the oxygenation index and defined as the Oxygenation stretch index. It was emphasized that it can better predict oxygenation and mortality.
OI is not used in the ARDS classification in adults. Adding airway pressure to the oxygenation equation is very important to standardize the severity of the disease. However, its effect on patient outcomes has not been determined as much as mean airway pressure, plateau, and driving pressure. In addition, no target recommendation has been presented in the PALICC guidelines. Plateau pressure is the end-inspiratory pressure and does not have a direct effect on PEEP. Since ventilator management is still heterogeneous in pediatric literature in line with the guidelines, it seems more logical to use driving pressure, which includes both inspiratory pressure and expiratory pressure. Within the framework of this information, adding driving pressure to the formula instead of Pmean (MAP) in the oxygenation index may be useful in evaluating both the severity of pARDS and the effectiveness of respiratory dynamics.
In our study, we will compare the Oxygenation Stretch Index with OI in patients with pARDS. We will examine its effects on parameters indicating lung damage, respiratory mechanics and patient outcomes.

What is being measured
The primary outcome is the main question the study is designed to answer.
Correlation of Oxygenation Index and Oxygenation Stretch Index in Acute Pediatric Respiratory Distress Syndrome (pARDS) Patiens in the PICU
By comparing the oxygenation stress index with the oxygenation index; it will be investigated whether it is a better parameter indicating lung damage. For this purpose, Oxygenation index and oxygenation stretch index will be correlated with mechanical power. Oxygenation index and oxygenation stretch index will be correlated with lung ultrasound score. Oxygenation index and oxygenation stretch index will be correlated with driving pressure. Oxygenation index and oxygenation stretch index will be correlated with transpulmonary pressure. Oxygenation index and oxygenation stretch index will be correlated with transpulmonary driving pressure.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Pediatric acute respiratory distress syndrome (pARDS) is a heterogeneous clinical syndrome that causes high rates of mortality and morbidity. The Pediatric Acute Lung Injury Consensus Conference (PALICC) guideline recommends using the oxygenation index (OI = mean airway pressure (MAP) × FiO2 /PaO2) for the diagnosis and classification of pediatric ARDS. Driving pressure (DP) is calculated by subtracting PEEP from plateau pressure. It is an important determinant of tidal volume in each breath and indirectly reflects lung stress.
It is the best parameter associated with mortality and lung injury in many studies. In the oxygenation index formula; adding driving pressure instead of Pmean may be more useful in evaluating the severity of pARDS. In our study, we will compare the Oxygenation Stress Index with OI in patients with pARDS. We will compare transpulmonary pressure, mechanical power, lung ultrasound score, and other respiratory mechanics, which are parameters indicating lung injury.

Questions about this trial
What is this clinical trial studying?
An observational study of Pediatric Acute Respiratory Distress Syndrome, run by Dr. Behcet Uz Children's Hospital at 7 sites 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 2 inclusion and 5 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 25 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 7 sites 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?
Correlation of Oxygenation Index and Oxygenation Stretch Index in Acute Pediatric Respiratory Distress Syndrome (pARDS) Patiens in the PICU (time frame: 2 hours). 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 NCT06586411, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
