Overview:

Combining the benefits of pressure and volume ventilation

The Puritan Bennett Volume Ventilation Plus software option combines the benefits of pressure and volume ventilation using Volume Control Plus and Volume Support modes.

In Volume Control Plus, clinicians set the inspiratory time and desired tidal volume. In Volume Support, clinicians set the desired tidal volume. The ventilator then adjusts pressure up or down to target a preset tidal volume.

Features

Features:

Puritan Bennett Volume Ventilation Plus software combines the advantages of a preset volume target with the ease of pressure control ventilation. The Volume Ventilation Plus software option allows clinicians simply to set the inspiratory time (Volume Control Plus or VC+ only) and desired tidal volume—the ventilator takes care of the pressure.

A pressure-based breath is delivered, and the Volume Ventilation Plus software option continuously increases or decreases pressure from breath to breath, targeting a preset volume to be delivered to the patient.

The active exhalation valve allows unrestricted exhalation during both inspiratory and expiratory phases of the breath cycle.
