Core Tip
Core Tip: This prospective observational study demonstrates a close association between mechanical power (MP), an integrative measure of ventilatory energy delivery, and lung aeration loss assessed by lung ultrasound score in patients with moderate-to-severe acute respiratory distress syndrome. Higher MP exposure was also associated with mortality and poor weaning outcomes. By linking ventilatory energy burden with bedside structural assessment of lung injury, this study highlights the potential value of combining MP and lung ultrasound to support physiologically informed and individualized ventilatory care.
