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