17.3 Setting up the ventilator PSV+VG
If Volume Guarantee is added to PSV, the Ventilator automatically is adjusting the PPSV level
necessary to maintain the preset Target Volume. In case of an Apnea, the Ventilator will start
cycling at a preset rate and PBackup. As soon as spontaneous activity restarts, the backup stops.
Settings to start with:
I-Flow:
8 L/min
E-Flow:
8 L/min
Frequency (Rate):
between
30 to
40
BPM – Safety backup rate in case of apnea
Inspiratory time:
between
0.3 to
0.4
sec – Used for backup and as max I-Time
Pbackup:
between
16 to
18
cmH
2
O – used during apnea backup ventilation
PBackup:
PPSV
16 to
18
cmH
2
O
PEEP:
4 to
6
cmH
2
O
The minimum pressure difference between PEEP and PPSV is always 2 cmH
2
O and PPSV is
limited not to exceed the set Pinsp.
PSV breaths and Apnea backup breaths are Volume Targeted Breaths in this mode.
The delay to start backup Ventilation is set with the Apnea time in Alarm Limit screen.
If Apnea is set to OFF > backup starts after E-time.
In PSV+VG mode, the patient controls the onset of Inspiration as well as the end of Inspiration,
offering a total synchrony with patients breathing pattern.
If patient lung compliance is improving, the Ventilator automatically is using the Lowest
Pressure, necessary to maintain the Preset Target Volume.
In case of a Respiratory fatigue and a ceasing Inspiratory effort, the ventilator automatically
provides an Apnea Backup Ventilation with the preset parameters for I-time, Frequency and
Pbackup.
The delay for the onset of the Apnea Backup Ventilation is set in the Alarm screen, by setting the
Apnea Delay Time. If Apnea Backup Ventilation is set to OFF, the ventilator starts Apnea Backup
Ventilation immediately after E-time, otherwise after Preset Apnea Time.
Using a delay time will determine the apnea period before backup ventilation begins.
The Apnea Backup breaths are Volume Guaranteed breaths.
