Trans Thoracic Manipulation of Ventilation/Perfusion: the V/Q System
United States15 participantsStarted 2020-08-11
Plain-language summary
The purpose of this pilot study is to measure the impact of non-invasive pneumatic manipulation of transthoracic pressure on oxygenation in patients with Acute Respiratory Distress Syndrome (ARDS) due to Coronavirus Disease 2019 (COVID 19) who are on mechanical ventilator support. This will be achieved by a pneumatic Vest placed around the chest wall of consenting patients who meet inclusion criteria. The Vest is essentially a non-invasive segmental device placed upon the anterior and posterior right and left aspects of the chest wall. The researchers have the ability to inflate and deflate the chambers of the Vest to achieve preset pressures as determined by the protocol and observe the patient's physiological response. Participants will have up to four hours of intervention with the study intervention, followed by 1 hour of post-intervention observation.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* 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.
* Ability of a Legally Authorized Representative (LAR) to provide consent on behalf of the patient.
Exclusion Criteria:
* 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
* Patients with pre-existing pulmonary hypertension and pulmonary fibrosis
* Bony chest trauma within the last 10 days
* Contraindications to esophageal manometry including recent esophageal trauma or surgery
* Abdominal compartment syndrome
* Active or recent gross hemoptysis
* Elevated intracranial pressure \>20 mmHg
* LAR refusal to participate
* Severe Scoliosis
* Morbidly obese (BMI \>37)
* Pregnant women
* Unable to maintain oxygen saturation \> 88%
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
