• The inspiration time is longer than the limit for maximal inspiration
time or when inspiration time reaches 3 seconds.
• The limit for the high-pressure alarm is reached.
PSV(TgV) – Pressure Support Ventilation with Target Volume
The PSV(TgV) mode acts as the PSV 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 45 delivers the desired set target vol-
ume 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-
sure and max pressure) in order to deliver the optimal support to the
patient.
PCV – Pressure Controlled Ventilation
In the PCV mode the ventilation is controlled by the Vivo 45. This is
done at the preset pressure, breath rate, inspiratory time, and rise time set-
tings set by the operator.
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 45, 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 45 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
