🫁 Workshop: How to Integrate Lung Ultrasound and Ventilatory Mechanics in pARDS? Using the case of Julián, a 4-year-old boy (16 kg) with severe pneumonia who progressed to hypoxemic respiratory failure requiring mechanical ventilation, this workshop addresses a key challenge in the PICU: how to interpret respiratory mechanics and lung ultrasonography in an integrated way to guide therapeutic decisions in pARDS. Using clinical, blood gas, and ventilator data, along with lung ultrasound findings from 12 zones, the workshop analyzes the relationship between lung aeration and variables such as tidal volume, PEEP, plateau pressure, and driving pressure. It discusses how changes in lung ultrasound reflect alveolar recruitment, persistent consolidations, and regional redistribution of ventilation, especially during interventions such as PEEP increases and prone positioning. The case demonstrates how lung ultrasound correlates with improved oxygenation and reduced ventilatory support, as well as its role in evaluating for weaning from mechanical ventilation. Diaphragmatic function parameters, such as excursion and thickening fraction, are also integrated for a more comprehensive assessment of the patient's ventilatory capacity. 🧠 Objective: To understand how to integrate lung ultrasound findings with ventilatory mechanics and diaphragmatic function to optimize recruitment, avoid overdistension, and make safe decisions in the management of pARDS. 🤝 Activity from the PICU Physiology Course 📺 Available on our channel 👉    / cursodefisiologiaenucip   💡 This case allows us to correlate lung ultrasound (LUS) with conduction pressure, PEEP, and prone positioning, understanding how regional changes in aeration guide ventilatory adjustments and the release strategy. #PICUPhysiology #LungUltrasound #MechanicalVentilation #ARDS #PICU #PediatricCriticalCareMedicine #LUS #RespiratoryMechanics #Prone #MedicalEducation
