Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial

Presentation with acute respiratory distress syndrome (ARDS) requiring intubation with mechanical ventilator support. ARDS will be defined by the ratio of the partial pressure of oxygen in the patient's arterial blood (PaO2) to the fraction of oxygen in the inspired air (FiO2) as being < 300.
Be older than 18 years old
Must not have
Morbidly obese (BMI >37)
Presence of cutaneous wounds that would be compromised by the Vest including stage 3 or greater pressure ulcers and the presence of actively treated burns
Timeline
Screening 3 weeks
Treatment Varies
Follow Up baseline, hour 1, hour 2, hour 3, hour 4, 1 hour post-intervention

Summary

This trial tests a special Vest that helps COVID-19 patients with severe lung issues breathe better. The Vest inflates and deflates to improve oxygen levels in the blood. It aims to provide a safer and simpler alternative to turning patients onto their stomachs.

Who is the study for?
This trial is for patients with severe breathing problems due to ARDS from COVID-19, who are on ventilators. They must have a specific oxygenation measurement (PaO2/FiO2 < 300) and consent from a legal representative. It's not for those with recent chest trauma, high brain pressure, certain esophageal conditions, pre-existing lung issues like pulmonary hypertension or fibrosis, skin wounds affected by the Vest device, severe scoliosis, extreme obesity (BMI >37), pregnant women or if they can't maintain an oxygen saturation above 88%.
What is being tested?
The study tests a non-invasive V/Q System Vest that manipulates chest pressure to improve oxygen levels in ARDS patients caused by COVID-19. The vest inflates and deflates around the patient's chest to change pressures while monitoring their response during and after a four-hour intervention period.
What are the potential side effects?
Potential side effects may include discomfort due to the pressure changes from the vest application. There could also be risks related to worsening of existing injuries or conditions such as hemoptysis (coughing up blood), increased intracranial pressure or aggravating any present cutaneous wounds.

Other Research
Common treatments for Acute Respiratory Distress Syndrome (ARDS) focus on improving oxygenation and minimizing lung injury. Mechanical ventilation strategies, such as low tidal volume ventilation (LTVV), aim to reduce ventilator-induced lung injury by using smaller breaths. Prone ventilation improves oxygenation by redistributing lung perfusion and ventilation. Conservative fluid management reduces pulmonary edema, thereby improving lung function. Pharmacotherapy, including glucocorticoids, can reduce inflammation in the lungs. The non-invasive pneumatic manipulation of transthoracic pressure, as studied with the Pneumatic Vest, aims to enhance oxygenation by externally adjusting chest wall pressures, potentially improving ventilation-perfusion matching without the need for invasive procedures. These treatments are crucial for ARDS patients as they address the underlying issues of hypoxemia and lung injury, which are central to the disease's high morbidity and mortality.
