What You Need to Know Before You Apply

What is the purpose of this trial?

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.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.

Is precision ventilation safe for humans?

Research shows that mechanical ventilation, if not properly adjusted, can worsen lung injury, but personalizing settings like PEEP (pressure to keep lungs open) may help reduce this risk. However, there is no consensus on the best method to personalize these settings, and more studies are needed to confirm safety. ^{1 2 3 4 5}

How does Precision Ventilation differ from other treatments for acute respiratory distress syndrome?

Precision Ventilation is unique because it personalizes mechanical ventilation settings based on individual lung characteristics and physiology, rather than using a one-size-fits-all approach. This method aims to minimize lung injury by adjusting parameters like tidal volume and positive end-expiratory pressure (PEEP) according to each patient's specific lung condition, potentially improving outcomes for those with acute respiratory distress syndrome. ^{1 3 4 6 7}

What data supports the effectiveness of the treatment Precision Ventilation for Acute Respiratory Distress Syndrome?

Research suggests that personalizing mechanical ventilation to individual lung conditions can help reduce lung injury and improve outcomes in patients with acute respiratory distress syndrome (ARDS). Studies indicate that adjusting ventilation settings based on specific lung characteristics, rather than using a one-size-fits-all approach, may enhance survival and minimize ventilator-induced lung injury. ^{1 3 4 5 7}

Are You a Good Fit for This Trial?

Adults over 18 with severe breathing problems due to Acute Respiratory Distress Syndrome (ARDS) can join this trial. They must be early in their ARDS course, currently on a ventilator, and not have been on it for more than 4 days. People with certain conditions like severe brain injury, recent major chest or stomach surgery, chronic lung issues, or those at high risk of bleeding are excluded.

Inclusion Criteria

I have been severely short of breath for no more than 10 days.

I was diagnosed with severe lung problems less than 2 days ago.

My symptoms started or got worse within a week of a medical event.

Exclusion Criteria

I have had issues or surgery related to my esophagus.

I have a muscle condition that affects my ability to breathe on my own.

I need extra oxygen daily, have lung scarring, or had a lung transplant.

What Are the Treatments Tested in This Trial?

Interventions

• Guided Usual Care Ventilation
• Precision Ventilation

Trial Overview The study is testing two ways to help patients breathe using a machine: the usual method versus a new 'precision' approach tailored to reduce lung stress. The main goal is to see if the personalized method improves survival rates for people with ARDS.

How Is the Trial Designed?

Group I: Precision ventilation Experimental Treatment 1 Intervention

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.

Group II: Guided usual care Active Control 1 Intervention

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.

Published Research Related to This Trial

A multicenter trial involving 420 patients with moderate-to-severe ARDS found that personalizing mechanical ventilation based on lung morphology did not significantly reduce 90-day mortality compared to standard care (hazard ratio 1.01).

Misclassification of patients' lung morphology was common (21%), and those misclassified had higher mortality rates when treated with personalized ventilation, suggesting that accurate phenotyping of ARDS is crucial for effective treatment strategies.

Constantin, JM., Jabaudon, M., Lefrant, JY., et al.[2020]

Mechanical ventilation can either worsen lung injury in patients with or at risk for ARDS or help reduce mortality if properly adjusted, highlighting the importance of personalized ventilation strategies.

Current practices often use a standard approach for setting tidal volume and PEEP, but evidence suggests that optimizing PEEP based on individual lung pathology rather than solely on oxygenation could improve patient outcomes, though no consensus exists on the best method for personalization.

In a study of 30 patients undergoing thoracic surgery, individualized positive end-expiratory pressure (PEEP) significantly improved oxygenation and lung mechanics during one-lung ventilation compared to a standardized PEEP of 5 cm·H2O.

The study group maintained higher arterial oxygenation levels (306 mm·Hg) and showed significant improvements in static compliance after adjusting PEEP, while the control group experienced decreased oxygenation, highlighting the efficacy of individualized PEEP in enhancing respiratory function.

Current strategies for treating acute respiratory distress syndrome (ARDS) focus on minimizing ventilation-induced lung injury (VILI) by personalizing mechanical ventilation based on individual patient respiratory mechanics.

Understanding the specific biophysical mechanisms of VILI, such as volutrauma and barotrauma, allows for better assessment and tailoring of lung-protective ventilation strategies, potentially reducing the risk of multiorgan failure associated with ARDS.

In a study involving anaesthetized rabbits, individualized physiological variable ventilation (PVV) showed significantly less lung injury compared to conventional pressure-controlled ventilation (PC), with lower lung injury scores and wet-to-dry lung weight ratios, indicating better lung protection.

PVV maintained stable respiratory elastance and adequate gas exchange over a 7-hour period, suggesting it could be a beneficial ventilation strategy during prolonged anesthesia when natural breathing is absent.

Recent research highlights the importance of tailoring mechanical ventilation strategies to individual patients' risk of lung injury, particularly in cases of acute respiratory distress syndrome (ARDS), where patients may exhibit different inflammatory responses.

A precision medicine approach to lung-protective ventilation should consider factors such as the patient's biological and mechanical predispositions to lung injury, the benefits of interventions, and the potential adverse effects of necessary cointerventions, rather than relying on a one-size-fits-all strategy.

Lung protection in acute respiratory distress syndrome: what should we target? Beitler, JR.[2022]

A personalized mechanical ventilation strategy for patients with ARDS, which considers lung physiology, imaging, and biological phenotypes, may enhance treatment outcomes, but more research is needed before implementation in clinical settings.

Monitoring specific ventilatory parameters, such as low tidal volume and driving pressures, along with techniques like esophageal pressure monitoring, can help tailor ventilation settings to individual patient needs, potentially improving safety and efficacy.
