Pressure, flow, and volume waveforms for a volume-cycle ventilator using a constant flow generator (square wave) at baseline (A), and with increased delivered tidal volume (B), reduced lung compliance (C), and enhanced respiratory flow rate (D). An increase in peak airway pressure occurs in the last three settings.
