Trans Thoracic Manipulation of Ventilation/Perfusion: the V/Q System

Brief 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.
