Pressure and flow waveforms during A pressure-controlled ventilation (PCV) and B volume-controlled ventilation (VCV). Measurements extracted from the waveforms and used in calculations of the expiratory time constant (τ) are highlighted. EOE end of exhalation (0.04 L/s), PEEP positive end-expiratory pressure, PEFR peak expiratory flow rate, PIP peak inspiratory pressure, PPLAT plateau pressure, VTe exhaled tidal volume
