Airway pressure/time waveforms from published papers [12] all using the airway pressure release ventilation (APRV) mode but with different methods: a Stock et al. used a CPAP phase that encompassed 60% of each breath, a release phase of 1.27 s and a respiratory rate (RR) of 20/min [98]; b Davis et al. decreased the respiratory rate by prolonging both the CPAP and release phase [99]; c Gama de Abreau et al. adjusted their CPAP and release phase to values typical of a conventional breath [100]; d Roy et al. minimized the release phase and extended CPAP to occupy 90% of each breath, typical of the time-controlled adaptive ventilation (TCAV) method [83]. Although these studies all used the APRV mode, each differs significantly in the application methods used to set the mode
