NCT06066502

Brief Summary

The goal of this interventional study is to compare standard mechanical ventilation to a lung-stress oriented ventilation strategy in patients with Acute Respiratory Distress Syndrome (ARDS). Participants will be ventilated according to one of two different strategies. The main question the study hopes to answer is whether the personalized ventilation strategy helps improve survival.

Study Arms (2)

Precision ventilation

EXPERIMENTAL

Ventilator support will be calibrated to maintain the range of lung stress typical of relaxed breathing in healthy adults. The ventilator management protocol takes into account pleural pressure, tidal volume and driving pressure, fraction of inspired oxygen (FiO2) and oxygen saturation (SpO2), and positive end-expiratory pressure (PEEP) titration.

Other: Precision ventilation

Guided usual care

ACTIVE COMPARATOR

Ventilator support will be managed by the clinical team per usual care with select protocol-based guard rails to avoid practice extremes beyond the current body of evidence. PEEP titration will be performed by the clinical team within the limits set in. The allowable combinations of PEEP and FiO2 in the control arm reflect pre-intervention usual care observed at baseline in the recent large federally-funded multicenter ARDS trials.

Other: Guided usual care ventilation

Interventions

The intervention arm prioritizes mitigation of ventilator-induced-lung-injury by individualizing support to patient-specific mechanics in an integrated approach to limit overdistension and atelectrauma. This is accomplished in this arm by titration of tidal volume to limitation of driving pressure at 12 centimeters of water (cmH2O) or less and using esophageal manometry to titrate PEEP to a transpulmonary pressure of 0 cmH2O with adjustments in respiratory rate to allow for permissive hypercapnia and FiO2 adjustments to assure adequate oxygenation.

Precision ventilation

The comparison arm allows clinician discretion when titrating PEEP and tidal volume, while setting general targets for allowable PEEP/FiO2 combinations, target range for SpO2, and target range for tidal volume. This arm applies routine best-practice guidelines. This includes maintenance of tidal volumes of 6-8 cc/kg of ideal body weight, limiting plateau pressures to 30 cmH2O or less and application of PEEP-FiO2 combinations which include a wide range of typical usual care with esophageal manometry only for data collection and not clinical adjustment.

  • Moribund patient not expected to survive 24 hours as assessed by the study physician; if cardiopulmonary resuscitation (CPR) was provided, assessment for moribund status must occur at least 6 hours after CPR was completed
  • Current limitation on life-sustaining care (other than do-not-resuscitate), or expectation by clinical team that a limitation on life-sustained care will be adopted within next 24 hours.
  • Treating clinician refusal or unwilling to use protocol-specified ventilator settings/modes

Intervention Model
PARALLEL
Model Details: Participants will be randomized to the intervention arm or control arm. Participants in the intervention group (precision ventilation), will have mechanical ventilation using settings directed by the amount of air pressure in the chest and lungs, using esophageal manometry. The treating clinical team is not masked to esophageal and transpulmonary pressure values and can view these data throughout the period of protocol-directed ventilation. Participants in the control group (guided usual care), will have ventilator support (low tidal volume mechanical ventilation) managed by the clinical team per usual care. The treating clinical team is masked to esophageal and transpulmonary pressure values and cannot view or be informed of these data at any time during the period of protocol-directed ventilation. An esophageal catheter will be inserted strictly for monitoring of respiratory mechanics by study staff, but values will not be used to titrate the ventilator.
