Target Volume
CAUTION!
If Target Volume is used with a patient circuit with an active exhalation valve, leakage
may be misinterpreted by the Vivo 65 as an increase of tidal volume. This will lead to a
decrease of the Inspiratory Pressure (the Inspiratory Pressure will not be lower than the
set Min Pressure). This may result in hypoventilation as the true delivered tidal volume
will decrease both as a result of the leakage and the decrease in Inspiratory Pressure.
This does not occur if a patient circuit with leakage port is used.
The Target Volume setting defines the tidal volume that the Vivo 65 will aim for while venti-
lating the patient in a pressure mode. To aim for the preset volume, the Vivo 65 will adapt
the Inspiratory Pressure between two adjustable pressure limits: Min Pressure and Max
Pressure.
When Target Volume is active, the mode field on the Vivo 65 display will indicate "(TgV)".

Max Pressure
The Max Pressure setting is only used when Target Volume is activated. Max Pressure
defines the upper pressure limit up to where the Vivo 65 can increase the pressure to reach
the set Target Volume. If Target Volume is not reached at Max Pressure, the Vivo 65 will
continue to ventilate at this Max Pressure setting.

Min Pressure
The Min Pressure setting is only used when Target Volume is activated. Min Pressure
defines the lower pressure limit down to where the Vivo 65 can decrease the pressure to
maintain the set Target Volume. If the actual volume is above Target Volume at Min Pres-
sure, the Vivo 65 will continue to ventilate at this Min Pressure setting.
