15. Figure 10 Auto-PEEP on a flow-time curveWhen the expiratory curve doesn't return to baseline before the next inspiration, the patient has auto-PEEP. 16

16. Figure 11 Auto-PEEP on an FV loopA flow-volume loop that doesn't close on the inspiratory curve indicates auto-PEEP. 17 Understanding ventilator waveforms—and how to use them in patient care Lian, Jin Xiong Nursing2020 Critical Care4(1):43-55, January 2009. doi: 10.1097/01.CCN.0000343236.47814.d8
