Function Specification
NIF Maximum negative pressure produced by patient’s spontaneous breathing within
a period of time.
PEEPi The PEEPi measure function supports measurement of two parameters: PEEPi
and Vtrap. PEEPi is the positive end-expiratory pressure produced by the
trapped gas and Vtrap is the trapped gas volume.
P-V By drawing static pressure-volume loop (static P-V loop), P-V tool is the method
to determine the optimal PEEP based on the characteristic points on the static
P-V loop.
ATRC ATRC stands for the function of automatic tube resistance compensation. By
selecting appropriate endotracheal (ET) tube or tracheostomy (Trach) tube of
different diameters for the user, the ventilator can adjust gas delivery pressure
automatically.
Sigh The sigh function is used to open collapsed areas of the lung or to keep the lung
open.
The sigh function can be activated in all ventilation modes except CPAP/PSV,
DuoLevel, and APRV.
Each time after the sigh function is activated, ventilation is controlled based on
the user-set sigh ventilation cycles and the set value of △int.PEEP. PEEP of the
sigh ventilation cycle increases △int.PEEP level. After that, sigh is
automatically switched off until next sigh time interval.
Screen Locking Prevents ventilator settings and values displayed from being changed due to
inadvertent key clicking.
