The inspiration stops and an expiration starts in two cases:
• The inspiration time expires.
• The limit for the high pressure alarm is reached.
PCV(A) – Assisted Pressure Controlled Ventilation
In the PCV(A) mode the ventilation is controlled by the Vivo 65, but the
patient has the possibility to start a breath through the Inspiratory Trig-
ger. This patient triggered breath will be delivered with the inspiratory
time, rise time and pressure setting set by the operator.
PCV(TgV) – Pressure Controlled Ventilation with Target
Volume
The PCV(TgV) mode acts as the PCV mode, but with an added regula-
tion of the pressure. Target volume is a feature that automatically adapts
the pressure to make sure that the Vivo 65 delivers the desired set target
volume to the patient. For every breath, the delivered volume is com-
pared to the set target volume. The delivered pressure for the next breath
will be increased or decreased depending on the difference between the
delivered volume and the set target volume. Automatic pressure adjust-
ments will be made in between two adjustable limits (min pressure and
max pressure) in order to deliver the optimal support to the patient.
PCV(A+TgV) – Assisted Pressure Controlled Ventilation
with Target Volume
The PCV(A+TgV) mode acts like the PCV(A) mode, but with an added
regulation of the pressure. Target volume is a feature that automatically
adapts the pressure to make sure that the Vivo 65 delivers the desired set
target volume to the patient. The delivered volume is compared to the set
target volume on a breath by breath basis. The delivered pressure for the
next breath will be increased or decreased depending on the difference
between the delivered volume and the set target volume. Automatic pres-
sure adjustments will be made in between two adjustable limits (min pres-
