Driving pressure and stress index are two important concepts used to think about lung stress, lung-protective ventilation, overdistension, tidal recruitment, and ventilator-induced lung injury. In this episode, we compare driving pressure with stress index, focusing on what each measurement means, how they are interpreted, how they relate to compliance and ventilator waveforms, and how they can inform mechanical ventilation strategy. Topics covered include: • What driving pressure is • What stress index is • Plateau pressure, PEEP, and driving pressure • Pressure-time waveform interpretation • Lung stress and strain during mechanical ventilation • Respiratory system compliance • Overdistension • Tidal recruitment and derecruitment • Stress index less than 1 • Stress index equal to 1 • Stress index greater than 1 • Driving pressure and lung-protective ventilation • Stress index and ventilator waveform analysis • Comparing driving pressure and stress index • Practical bedside applications and limitations Watch the full video on YouTube: https://www.youtube.com/watch?v=fULtSMAxMJ8 📚 Want More Emergency & Critical Care Medicine Education?
