Abstract

Yellow curve: Pressure (cmH2O) on X-axis and Time (seconds) on Y-axis
Pink curve: Flow (L/sec) on X-axis and Time (seconds) on Y-axis
Green curve: Tidal volume (ml) on X-axis and Time (seconds) on Y-axis

Two patients with respiratory failure secondary to COPD exacerbations are undergoing a spontaneous breathing trial with Pressure support ventilation 5 cmH2O and PEEP of 5 cmH2O with 25% expiratory cycle.
Who is more likely to be liberated safely, who might pass, and who might fail?
