About this study
Official title: Randomized Crossover Trial To Compare Closed-loop FiO2 Controller With Conventional Control of FiO2 During High Flow Oxygen Treatment In Pediatric Intensive Care Unit Patients
Recently, high flow oxygen therapy (HFOT) is becoming more popular in the treatment of any kind of respiratory failure. Pediatric mechanical ventilation consensus conference (PEMVECC) guidelines suggest measuring oxygen saturation by pulse oximetry (SpO2) in all ventilated children and furthermore to measure partial arterial oxygen pressure (PaO2) in moderate-to-severe disease in order to prevent excessive use of oxygen while preventing hypoxemia and hyperoxemia. This study aims to compare the safety and efficacy of a closed-loop FiO2 controller (CLOC) with conventional control of FiO2 during HFOT of pediatric patients in a pediatric intensive care unit (PICU). The hypothesis of this study is: Close-loop FiO2 controller increases the time spent within clinically targeted SpO2 ranges and decreases the time spent outside clinical target SpO2 ranges as compared to manual oxygen control in PICU patients treated with HFOT.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Close-loop FiO2 controllerDevice
Close-loop FiO2 controller software option provides automated adjustment of the ventilator Oxygen setting to maintain the patient's SpO2 in a defined target range. When using the software option, the user defines the SpO2 target range, as well as the SpO2 emergency limits, and the device adjusts the FiO2 setting to keep the patient's SpO2 in the target range.
ConventionalDevice
Conventional FiO2 adjustment by the clinician according to SpO2 values

|---|---|---|
| Close-loop FiO2 Controller | Experimental | Two hours period where the fraction of inspired oxygen (FiO2) delivered will be automatically titrated based on SpO2 values obtained from the patient. Receives: Device: Close-loop FiO2 controller |

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Recently, high flow oxygen therapy (HFOT) is becoming more popular in the treatment of any kind of respiratory failure. Pediatric mechanical ventilation consensus conference (PEMVECC) guidelines suggest measuring oxygen saturation by pulse oximetry (SpO2) in all ventilated children and furthermore to measure partial arterial oxygen pressure (PaO2) in moderate-to-severe disease in order to prevent excessive use of oxygen while preventing hypoxemia and hyperoxemia. This study aims to compare the safety and efficacy of a closed-loop FiO2 controller (CLOC) with conventional control of FiO2 during HFOT of pediatric patients in a pediatric intensive care unit (PICU). The hypothesis of this study is: Close-loop FiO2 controller increases the time spent within clinically targeted SpO2 ranges and decreases the time spent outside clinical target SpO2 ranges as compared to manual oxygen control in PICU patients treated with HFOT.

Questions about this trial
What is this clinical trial studying?
A study testing Conventional in people with Respiratory Failure, run by Dr. Behcet Uz Children's Hospital at 2 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 3 inclusion and 11 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 30 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 2 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?
Percentage of time spent in optimal SpO2 range (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 NCT05032365, which also lists 7 linked publications.
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 30 Jan 2023.
