5.11.5 Waveform Autoscaling
If the measured values of Paw, Flow, or Volume are larger than the boundary at the end of the
breath cycle, the system will autoscale the Paw, Flow, or Volume at the beginning of next breath
cycle.
If the measured values of Paw, Flow, or Volume are less than the boundary minus a margin (see
TABLE5-1) at the end of two continuous breath cycles, the system will autoscale the Paw, Flow, or
Volume at the beginning of the next breath cycle.
