Figure 5.6 Adaptive Bi-Level Mode
The V
T
display shows the estimated Tidal Volume delivered to
the patient calculated using the measured flow leak during P-
low. An estimated Leak is shown below the V
T
/Exhale field of
the display.
The Leak Estimate value is shown as Liters/Minute. Estimates
of V
T
/Exhale are disregarded at leaks above 40 Liters/minute.
5.7 Easy Exhale™
Easy Exhale is an advanced PEEP mode for use in the
circumstance of severe obstructive airway flow limitation in
which clinically important critical airway closure results in
intrinsic PEEP. Its purpose is to improve downstream airway
emptying while potentially matching intrinsic PEEP to
optimize alveolar ventilation. In this mode, the ventilator
circuit is depressurized through the initial phase of expiration
to facilitate downstream dead space ventilation. The
introduction of PEEP to the ventilator circuit late in expiration
prevents airway pressure from falling below alveolar pressure
with resultant auto-PEEP.
