Function description Oxylog 2000 plus
1 General The Oxylog 2000 plus is a time-cycled, volume controlled emergency and
transport ventilator with pressure support for patients requiring mandatory or
assisted ventilation with a tidal volume from 100 mL upwards. For use by and
under supervision of trained health care professionals.
2 Functional principle Oxylog 2000 plus primarily comprises the pneumatic components with the
connection and metering block and the control and display electronics (Fig.
1).
The connection block supplies a constant pressure to the metering block,
contains the safety functions such as the emergency air and safety valves,
control the pressure (PEEP) during expiration and, together with the ventila-
tion accessories, provides the interface to the patient.
The metering block passes defined volumes of gas of approx. 40% or 100%
oxygen to the connection block.
The control and display electronics evaluate the measurement signals, con-
trol the valves and provide the interface to the operator.
