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.
