During the time window, if patient effort is detected, either a
Spontaneous or an Assist breath is delivered for the first effort. If the
last breath delivered was Mandatory, then a Spontaneous breath is
delivered for the first patient effort of the window. If the last breath
delivered was an Assist or Spontaneous breath, then an Assist breath
is delivered for the first patient effort of the window. Assist breaths
deliver the Pressure setting during inhalation and the PEEP setting
during exhalation.
During the time window, if patient effort continues to be detected
(after the first patient triggered breath), Spontaneous breaths are
delivered for the remainder of the window. The figure below provides
example breath patterns in PC-SIMV mode.
