After initiation of mechanical ventilation and assessing the eligibility of the patient, informed consent will be taken from the closest kin. If eligible, following steps will be performed which are part of standard ARDS patient care.~Low-flow Pressure Volume curve and assessment of airway opening pressure~Calculation of recruitment to inflation ratio~Optimizing Positive End-Expiratory Pressure~Afterwards, phase III slope of the patient will be recorded at four timepoints:~Supine 1 (immediately before turning to prone position) Prone 1 (immediately after prone position) Prone 2 (at the end of the 16-24 hour prone cycle) Supine 2 (immediately after turning to supine position)
This study evaluates the effects of prone positioning on homogenization of ventilation.
