A Prospective Clinical Study to Explore Response to Prone Positioning in ARDS Patients

Enrolled subjects will undergo LUS 1 hour before and 1 hour after prone positioning by a trained clinician and will be assessed using a LUS score based on LUS pattern. LUS will then be performed again 1 hour before supination (16 hours) and assessed by a LUS score. This process will be repeated on the first 3 prone sessions. Patients will be enrolled in the study for 4 weeks in order to observe patient outcomes.
