Brief Summary

This is a multicenter randomized controlled clinical trial with an adaptive design assessing the efficacy of setting the ventilator based on measurements of respiratory mechanics (recruitability and effort) to reduce Day 60 mortality in patients with acute respiratory distress syndrome (ARDS). The CAVIARDS study is also a basket trial; a basket trial design examines a single intervention in multiple disease populations. CAVIARDS consists of an identical 2-arm mechanical ventilation protocol implemented in two different study populations (COVID-19 and non-COVID-19 patients). As per a typical basket trial design, the operational structure of both the COVID-19 substudy (CAVIARDS-19) and non-COVID-19 substudy (CAVIARDS-all) is shared (recruitment, procedures, data collection, analysis, management, etc.).
