Control Limiting
V*Home restricts the availability of some control settings when the set value of another interdependent control creates
a limit. For example, available PEEP and Pressure Control settings are interdependent and control limited. If the PEEP
control is set to 25 cmH2O, the available Pressure Control settings are automatically limited to 25 cmH2O or less to
prevent VOCSN from delivering a total maximum pressure exceeding 50 cmH2O.
If a limit is reached during control conguration, V*Home will display a message on the conguration screen, indicating
which interdependent control is limiting available settings. To adjust the setting of a control beyond its control limit, the
interdependent control setting must be changed rst.
The table below lists controls that are interdependent and control-limited, and describes the reason for the limit
Controls Control limited to ensure:
Breath Rate (including Apnea
Rate) and Inspiratory Time
The maximum inspiratory time will not exceed 0.5, multiplied by 60, divided by the set Breath Rate
(or Apnea Rate). This is to prevent inverse I:E ratios.
EPAP and IPAP The set IPAP is greater than the set EPAP, and the total delivered pressure will not exceed
40 cmH2O.
High Pressure alarm and
Pressure Control or Pressure
Support
The High Pressure alarm is not set less than 3 cmH2O above the set Pressure Control or Pressure
Support.
Mode and Circuit Type
controls for the active
Ventilation Preset
Controls are congured at intended settings before beginning therapy.
PEEP and Pressure Support The total delivered pressure will not exceed 40 cmH2O.
PEEP and Pressure Control The total delivered pressure will not exceed 50 cmH2O.
Pres. Minimum, PEEP, and
High Pressure alarm
To ensure the minimum pressure of breaths is less than the maximum pressure of breaths during
Volume Targeted ventilation.
Tidal Volume and Inspiratory
Time
Volume breaths will not deliver a ow greater than 120 L/min, or less than 10 L/min.
