1.0 Theory of Operation 1.1 Introduction The AS3000 is a continuous flow anesthesia system which offers manual or automatic ventilation, easily adjustable fresh gas delivery, anesthetic agent delivery, ventilation monitoring, convenient ergonomics, and state-of-the-art safety systems. The components of the AS3000 Anesthesia System are described this chapter. AS3000 Service Manual 0070-10-0683 1 - 1
Microprocessor-controlled Ventilator Theory of Operation 1.2 Microprocessor-controlled Ventilator The Microprocessor-controlled ventilator, with its dedicated Breathing System, allows time- controlled, pressure limited, constant volume ventilation for all patient groups within a tidal volume range of 40 mL (4 kg infant) to 1400 mL (large adult). Time-controlled, pressure limited, and compliance compensated constant volume ventilation is provided through the Controlled Mandatory Ventilation (CMV) mode. The CMV mode delivers a viable ventilation method for complicated lung conditions. The ventilator also provides time-controlled, volume dependant ventilation, targeting a set (adjustable) target pressure provided through the Pressure Controlled Ventilation (PCV) mode. Automatic and comprehensive system startup tests and alarm management systems ensure controlled ventilation conditions in every mode of operation. The durable and ergonomically designed user interface and Navigator Knob enables easy operation. The display provides the selected ventilation modes (CMV, PCV, PS and SIMV) and the following values: Tidal Volume, Peak Pressure, Mean Pressure, FiO2, Breath Rate, I:E Ratio, PEEP, Plateau Pressure, Alarm limits, and real-time Airway Pressure and flow waveform.
