5.8 Automode
In Automode, the ventilator system shifts
automatically between controlled and
supported ventilation, allowing better
patient-ventilator interaction. When the patient
is making a breathing effort, the ventilator
system immediately switches to a supported
mode of ventilation. If the patient is not making
any breathing effort, the ventilator system will
return to the controlled mode and deliver
controlled breaths.
The parameters for each Automode
combination are adjusted in the settings
window and are basically the same as those
for the relevant controlled or supported mode.
Refer to section Settings on page 43.
Automode PC
⇄
PS:
• is an interactive mode automatically
switching between the controlled mode PC
and supported mode PS based on patient
triggering
• delivers controlled breaths in the absence
of patient breathing effort, switching to
supported breaths when a breathing effort
is detected
• serves as an aid to starting the weaning
period
• adapts to the patient’s breathing capacity
Automode PRVC
⇄
VS:
• is an interactive mode automatically
switching between the controlled mode
PRVC and supported mode VS based on
patient triggering
• delivers controlled breaths in the absence
of patient breathing effort, switching to
supported breaths when a breathing effort
is detected
• serves as an aid to starting the weaning
period
• adapts to the patient’s breathing capacity
In this combination, the first supported breath
delivered to the patient has the same pressure
level as the preceding PRVC breath.
Automode VC
⇄
VS:
• is an interactive mode automatically
switching between the controlled mode VC
and supported mode VS based on patient
triggering
• delivers controlled breaths in the absence
of patient breathing effort, switching to
supported breaths when a breathing effort
is detected
• serves as an aid to starting the weaning
period
• adapts to the patient’s breathing capacity
In this combination, the ventilator system uses
the plateau pressure in the VC breath as a
reference pressure for the first VS breath.
