Brief Summary
Acute respiratory distress syndrome (ARDS) is a serious and potentially life-threatening lung condition that can affect children. Currently, ventilator settings commonly used in treatment are based on approaches developed for adults, and it remains unclear whether these settings are equally effective for children. Because children's bodies respond differently than adults', it is important to determine the most effective ventilator strategies specifically for pediatric patients. This study will compare two different ventilator approaches in children with ARDS to identify which method provides the greatest benefit. The findings will also help inform the design of a larger study in the future.

Outcome Measures
Primary Outcomes (1)
Sustained Resolution of Hypoxemia
The primary outcome of PARMA is time (in hours) per participant to sustained resolution of hypoxemia, defined as being alive with PaO2/FIO2 (measurement of the amount of oxygen dissolved in the blood plasma/concentration of inhaled oxygen) \> 300 (or SpO2/FIO2 (measurement of the percentage of hemoglobin in your blood that is carrying oxygen/concentration of inhaled oxygen) \> 315) on two consecutive measurements 4 hours apart. This outcome is censored at 28 days (672 hours).
Up to 672 hours
Secondary Outcomes (14)
Imaging (Electrical Impedance Tomography (EIT)): Lung recruitment
Once from time of enrollment to randomization, once within 8 hours post-randomization and once within 24-72 hours after randomization.
Imaging (Electrical Impedance Tomography (EIT)): Overdistension
Once from time of enrollment to randomization, once within 8 hours post-randomization and once within 24-72 hours after randomization.
Imaging (Electrical Impedance Tomography (EIT)): Center of Ventilation
Once from time of enrollment to randomization, once within 8 hours post-randomization and once within 24-72 hours after randomization.
Clinical End Point: all-cause mortality at 90 days
From enrollment up to hospital discharge, no longer than 90 days.
Clinical End Point: all-cause mortality at 28 days
From enrollment up to hospital discharge, no longer than 28 days.
- +9 more secondary outcomes
Study Arms (2)
High Driving Pressure Mechanical Ventilation
ACTIVE COMPARATORA participant who is already on the breathing machine will have the driving pressure set to 25 cmH2O (rate of pressure delivery). All other standard clinical care for this participant will stay the same based on what their clinical team chooses to do.
Low Driving Pressure Mechanical Ventilation
ACTIVE COMPARATORA participant who is already on the breathing machine will have the driving pressure set to 15 cmH2O (rate of pressure delivery). All other standard clinical care for this participant will stay the same based on what their clinical team chooses to do.
Interventions
A participant who is already invasively mechanically ventilated will be placed on "Pressure Control Ventilation" mode on an Evita V500 (Manufacturer: Dräger, Lübeck, Germany) ventilator if they are not already. The driving pressure will be set to 25 cmH2O (rate of pressure delivery). The Children's Hospital of Philadelphia (CHOP) PICU's standard of care regarding sedation, fluid management, ventilator weaning, and extubation readiness for invasively mechanically ventilated children will be adhered to for the duration of the study. An Enlight 2100 Electrical Impedance Tomography (EIT) Device (Manufacturer: Timpel) strap will be placed across the participant's chest up to four times throughout the study for a few hours to image the aeration in the lungs.

Eligibility Criteria
You may qualify if:
- age \> 2 weeks (\> 38 weeks corrected gestational age) and \< 18 years (not yet had 18th birthday)
- acute (≤ 7 days of risk factor) respiratory failure requiring invasive mechanical ventilation
- ventilated with endotracheal tube or tracheostomy for ≤ 7 days from risk factor onset
- hypoxemia defined as PaO2/FIO2 (measurement of the amount of oxygen dissolved in the blood plasma/concentration of inhaled oxygen) \> 300 (or SpO2/FIO2 (measurement of the percentage of hemoglobin in your blood that is carrying oxygen/concentration of inhaled oxygen) \> 315 on Positive End-Expiratory Pressure (PEEP) ≥ 5 cmH2O (rate of pressure delivery) on two consecutive measurements 4 hours apart and sustained at the time of consent and randomization
- bilateral opacities on chest radiograph as determined by radiologist, clinical attending, or PI
You may not qualify if:
- hypoxemia caused primarily by hydrostatic pulmonary edema from heart failure or fluid overload
- non-palliated or unrepaired cyanotic congenital heart disease
- ventilated via tracheostomy at baseline prior to acute illness
- obstructive airway disease determined to be the primary cause of respiratory failure
- severe moribund state not expected to survive \> 72 hours
- any limitations of care at time of screening
- escalation to high frequency oscillatory ventilation or extracorporeal support (i.e., meeting PARMA protocol failure criteria) at time of screening
- previous enrollment in this study

- Will share
- Shared Documents
- STUDY PROTOCOL, SAP, ICF, CSR
- Time Frame
- Individual participant data (IPD) will be shared 1 year after main manuscript publication.
- Access Criteria
- The IPD will be made readily available for research by qualified individuals within the scientific community as determined by DASH's regulatory and contractual requirements. The dataset will be accessible via the DASH platform.
De-identified trial dataset, stripped of all personal health information, will be shared with an existing NIH data repository (likely the National Institute of Child Health and Human Development (NICHD) Data and Specimen Hub (DASH)).
