This research investigates how mechanical ventilation affects blood flow in the diaphragm, the primary muscle responsible for breathing. Using ultrasound and contrast imaging, the study aims to improve understanding of diaphragm weakening during ventilator support, helping clinicians make safer decisions about when patients can breathe independently again.

Acute respiratory distress syndrome (ARDS) causes severe breathing failure and kills tens of thousands annually, yet has no effective treatment. This research studies how ARDS disrupts lung surfactant, a critical stabilizing substance in the lungs. By identifying immune-related factors that damage surfactant, the work aims to develop the first targeted therapeutic cure.
