1 The changes in peak flow and inspiratory time between a minimum rise time (first 2 breaths) and a maximum rise time (last 2 breaths), with the Servo-i ventilator. The changes in peak flow and inspiratory time between a minimum rise time (first 2 breaths) and a maximum rise time (last 2 breaths), with the Servo-i ventilator. The cycling criteria was set to minimum for all 4 breaths. The peak flow is lower and the inspiratory time is longer in the first 2 breaths, compared to the last 2 breaths. Joshua F Gonzales et al.
