LIAM can only be enabled by the doctor and only triggered during ventilation. The
maneuver includes at least one LIAM stroke consisting of insufflation and subsequent
exhalation.

Cycles
Your doctor uses the Duration parameter to specify the period for which LIAM is applied.
The Interval parameter states at what intervals LIAM will be repeated. Within one interval,
either one LIAM stroke (Cycles = 1) or up to 10 consecutive LIAM strokes are executed.
LIAM to support a coughing maneuver
LIAM can be used to support a coughing maneuver by initially expanding lung and thorax
adequately during hyperinsufflation. This makes more air available for the subsequent
cough. At the same time, optimized initial tensioning of the lung and thorax increases the
effectiveness of the cough on exhalation.
