With a ramp ow pattern, the airow starts high and decreases
throughout inspiration of the breath.

TIME
For the active circuit in volume modes, peak ow is required to be
a minimum of 20 l/min. The wave form may be attened when the
combination of Inspiratory Time and Tidal Volume set points would
result in a ow of less than 20 l/min. Therefore, for some settings,
a Ramp ow pattern may provide a pattern that more closely
resembles a Square ow pattern.
