Sigh settings

The Sigh breath feature allows the user to program the delivery of a 'sigh breath' at a regular interval
(sigh interval) within the currently delivered breathing pattern.
The sigh breath is a magnified version of the primary breath (Magnification factor set from 120 to 250%).
For pressure-target breaths, the inspiratory duration and P control are magnified proportionally.
For volume-target breaths, volume is magnified.
