Limitations of setting parameters

In adjusting the setting parameters in different modes, some respiratory parameters limit each
other. These restrictions are divided into several categories:
- Dependence of Rate, Flow and Vti
- Dependence of Rate and Ti
- Dependence of Plow, Phigh, Psupport, Ppeak, PEEP and High pressure alarm limit
that shown in the following table:
Restrictions of parameters
PEEP + P
PEEP + P
PEEP + 10 ≤ HPresAlarm
PEEP + 7 ≤ HPresAlarm

support
Plow + 7 ≤ HPresAlarm
Plow + 3 ≤ Phigh
PHigh + 5 ≤ HPresAlarm
Warning
Note that while changing the respiratory modes, setting parameters may be
limited depending on the circumstances.

Leak Compensation

The leak compensation function is used to compensate leakages of flow during the inspiration
and expiration. To prevent long inspiration time in the volume modes, the volume will be
increased through inspiratory flow. In order to make the delivered volume to the patient equal
to the preset volume, the measured flow leakage is added to the set flow as a constant value.
The added leakage value to the set flow is calculated according to the below table.
Leakage compensation capability can be selected in all breathing modes.
