Posterior Aeration Loss on Lung Ultrasound in Mechanically Ventilated Critically Ill Patients Without Pulmonary Pathology

The value of lung ultrasound in critically ill patients extends to several diagnostic1 and monitoring2 protocols for pulmonary pathologies. Current literature encompasses studies is limited to the use of lung ultrasound findings in assessment of pulmonary pathologies.3 As lung ultrasound emerges as a standard clinical tool, critically ill patients without clear pulmonary pathology also undergo lung ultrasound examination. It becomes imperative to gain insights into baseline lung ultrasound appearances in these patients without clear pulmonary pathology to understand clinical trajectories and to incorporate the lung ultrasound findings into clinical practice.
