Configure Settings
Configure all ventilator settings from the Vent Run Screen.
Pressure Priority :
RoVent ventilates to a specified inspiratory pressure. The default
target pressure is 15cmH2O independent of body weight setting. To change the
target pressure, touch
Set Target Pressure
.
Volume Priority:
RoVent delivers an initial target pressure for the first breath, then
delivers a target tidal volume. The default target tidal volume is calculated based on
body weight. To change the target tidal volume, touch
Set Target Volume
.
Note: You can change the initial target pressure for the
first breath, as well as the minimum and maximum allowed
pressures to customize the ventilator’s operating range as the
ventilator delivers the set tidal volume.
The Vent Setup also allows you to make advanced ventilation settings:
• PEEP: Automatically add a positive end-expiratory pressure.
o Choose between 0cmH2O and 9cmH2O.
o Used to prevent alveolar collapse during open-chest procedures.
• Sigh Breath: Automatically add an intermittent breath with a larger tidal volume.
o Choose frequency and tidal volume of sigh breaths.
o Evenly distributes inspiratory pressure to prevent partial alveolar collapse.
• I/E Ratio: Change the breath mechanics.
o Choose the ratio of inspiratory to expiratory portions of a breath cycle.
o Useful to increase oxygenation in certain respiratory models.
• Inspiratory Pause: Change the breath mechanics.
o Choose the time between the end of active inspiration and the start of
expiration.
o Useful to increase oxygenation in certain respiratory models.
• Assist Mode: Change the breath pattern.
o Choose how an animal is allowed to breathe at a spontaneous respiration rate,
while the ventilator retains control of target inspiratory pressure or target tidal
volume.
o Useful during recovery from long procedures, or in certain respiratory models.
