Using SIPPV
SIPPV = Synchronized controlled ventilation
In SIPPV mode, the controlled ventilation strokes can be
triggered within a time period and synchronized with the
patient's inspiratory effort!
The ventilation frequency in this mode is higher than that
set.
If there is no inspiratory effort by the patient, the ventila-
tion strokes are automatically applied by the machine at
the set frequency.
● Set ventilation initially as described for IPPV mode,
page 7.
Then:
1 Press »M Info« key to obtain the display:
IPPV SIPPV.
2 Press »g Reset« to confirm and SIPPV mode is
applied by the machine.
The maximum inspiration time is always limited to
1.3 seconds. The following warning message appears if
the measured frequency exceeds the set frequency by
more than 50 %:
Using SIMV
SIMV = Synchronized intermittent mandatory ventilation
SIMV is a combination of mechanical ventilation and
spontaneous breathing, with spontaneous breathing
possible between the ventilation strokes. If the patient
does not breathe spontaneously within a time period, the
machine automatically applies a mechanical ventilation
stroke.
When mechanical ventilation strokes are being applied at
low frequencies, the trigger window should not be more
than 6 seconds in order to guarantee a minimum expira-
tion time of 0.5 seconds. The duration of the trigger
window decreases as the frequency of mechanical
ventilation strokes increases.
With synchronization, the mechanical ventilation stroke is
applied during a preset period to coincide with the
patient's inspiratory effort. The frequency of the
mechanical ventilation strokes remains constant.
Synchronization is briefly indicated by a star (*) apearing
in the display.
