7 Description of the modes
• The ASB function is used for pressure support of insufficient
or exhausted spontaneous breathing. The patient is able to
breathe spontaneously without any restriction, but is
supported in his breathing effort by the device.
The CPAP + ASB mode is used exclusively on patients with
adequate spontaneous breathing.
In principle, the pressure is set at the end of expiration (PEEP).
If necessary, the pressure support (ΔpASB ) can be switched on.
Ventilation can be individually adjusted to suit the patient with
the aid of the inspiratory and expiratory triggers. The inspiratory
trigger indicates a sensitivity for triggering pressure support.
The expiratory trigger determines when the device interrupts
pressure support. This allows the administered volume and the
inspiration time to be set indirectly.
The set maximum ventilation pressure (pMax) ensures the safety of
the patient.
