Impact Univent 750 Transport Ventilator
The Uni-Vent 750 Portable Ventilator is a portable electronically controlled, time cycled, pressure limited ventilator. It is controlled by an on board microprocessor which continuously monitors the patients airway pressure, all control settings, alarm parameters and power signals.
Control Module: Front panel of ventilator where the controls and indicators are located.
This panel is accessed by unlocking and lifting the clear cover. All of the ventilator functions and settings are done from the Control Module.
Mode Selector Switch: Turn the ventilator on and allow it to perform a “self check”. After the self
check has completed you can use the Control Module to make adjustments
to the settings and select the operation mode according to the patient’s
CTRL – Cycles in accordance with Rate, Inspiration time and Flow
ASSIST – Cycles in accordance with Rate, Inspiration time and Flow
Adjust, but will sense the patient’s attempts at spontaneous respiration
and “assist” the patient with the Flow and Inspiration time settings.
Control takes over when the rate is to low or no spontaneous respirations
SIMV – Will intermittently deliver a controlled breath at the Rate control
setting, and synchronize to the patient’s spontaneous respirations. The
patient breathes at their normal rate and volume until the next controlled
Flow Adjust: The Flow Adjust will allow for the user to adjust the Tidal volume
delivered. It is used in conjunction with the Inspiration Time.
(Calibrated for 50psi input pressure)
Example: Flow Adjust set at 500 ml/SEC and Inspiration Time set at 1.5
SEC will deliver a Tidal Volume of 750 ml. (see the back of the ventilator
for a Computation Chart)
Tidal volume = 6 Liters/Kg
