Assist/Control-Pressure Mode
Assist/Control-Pressure works one way with passive and valveless circuits, and differently when V*Home is connected to
and congured to use a mouthpiece Ventec One-Circuit.
Assist/Control-Pressure with a Passive, or Valveless Ventec One-Circuit
When used with a passive, or valveless Ventec One-Circuit, Assist/Control-Pressure mode provides mandatory and assist
pressure breaths, depending on the timing of detected patient effort. Patient effort will trigger an assist pressure breath.
If no patient effort is detected within a breath period, V*Home will provide a mandatory pressure breath.
Both mandatory and assist breaths are delivered at the set Pressure Control (above PEEP)
1
over the set Inspiratory Time.
When a breath cycles, the pressure of the Ventec One-Circuit drops to the set PEEP.
Assist/Control-Pressure with a Mouthpiece Patient Circuit
When used with a mouthpiece patient circuit, Assist/Control-Pressure mode provides assist pressure breaths when
patient effort is detected.
Assist breaths are delivered at the set Pressure Control over the set Inspiratory Time. Since mouthpiece circuits are not
always held in the mouth, the pressure of the patient circuit drops to zero when a breath cycles.
1 In Assist/Control-Pressure mode, the peak pressure delivered is the set Pressure Control plus the set PEEP. Set the Pressure Control
to the prescribed pressure to be delivered during inspiration, as an addition to the set PEEP. For example, a PEEP setting of 5
cmH2O and Pressure Control setting of 10 cmH2O will result in a peak pressure of 15 cmH2O.
