Microprocessor-controlled Ventilator Theory of Operation<br />
1.2 Microprocessor-controlled Ventilator<br />
The Microprocessor-controlled ventilator, with its dedicated Breathing System, allows time-<br />
controlled, pressure limited, constant volume ventilation for all patient groups within a tidal<br />
volume range of 40 mL (4 kg infant) to 1400 mL (large adult).<br />
Time-controlled, pressure limited, and compliance compensated constant volume ventilation<br />
is provided through the Controlled Mandatory Ventilation (CMV) mode. The CMV mode<br />
delivers a viable ventilation method for complicated lung conditions. The ventilator also<br />
provides time-controlled, volume dependant ventilation, targeting a set (adjustable) target<br />
pressure provided through the Pressure Controlled Ventilation (PCV) mode. Automatic and<br />
comprehensive system startup tests and alarm management systems ensure controlled<br />
ventilation conditions in every mode of operation.<br />
The durable and ergonomically designed user interface and Navigator Knob enables easy<br />
operation. The display provides the selected ventilation modes (CMV, PCV, PS and SIMV)<br />
and the following values: Tidal Volume, Peak Pressure, Mean Pressure, FiO2, Breath Rate, I:E<br />
Ratio, PEEP, Plateau Pressure, Alarm limits, and real-time Airway Pressure and flow<br />
waveform.<br />
