Auto - PEEP

Auto-PEEP is a teaching app about leftover pressure in the lung. Auto-PEEP appears when the lung has not finished emptying before the next breath starts. Air stays trapped. The next breath begins above the resting volume of the lung. The learner watches two pictures of the same breath: • Paw — airway pressure • Flow — whether flow is still leaving when the next breath starts An empty lung reaches its resting volume before the next breath. A trapped lung does not. On the pressure–volume loop, the trapped breath does not close. The five screens are: 1. What — empty lung versus trapped lung 2. Why — rate too high, inspiratory time too long, or airway resistance too high 3. Cases — the same lesson in a neonate, an infant, and an adolescent 4. Info — what to look for on a ventilator screen 5. Refs — the papers behind the lesson
