Biophysical surfactant properties of isolated large surfactant aggregates from healthy volunteers (Control) and patients with cardiogenic lung edema (CLE), ARDS (with extrapulmonary trigger), severe pneumonia necessitating mechanical ventilation (PNEU), or ARDS and lung infection (ARDS + PNEU). Surface tension [mN/m] at minimum bubble size after 5 min of film oscillation (γ min) is given (pulsating bubble surfactometer, at 2 mg/ml phospholipid). Single events (circles), means (triangles), and medians (squares) are indicated. ***(P < 0.001). From [26], with permission.
