  • Page 10: General

    Function description Oxylog 2000 plus 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.

  • Page 11: Pneumatic Assembly

    Oxylog 2000 plus Function description Pneumatic assembly The following description relates to the pneumatics diagram of the Oxylog 2000 plus. The Control PCB evaluates the measurement signals of the sen- sors and actuates the valves. Inlet The compressed oxygen passes through the filter F1 and the pressure regu- lator DR to the valves V1 to V3.

  • Page 12: Peep Valve

    Function description Oxylog 2000 plus Fig. 2 Functional principle of the external flow sensor Pressure sensor S5 measures the pressure at the patient. Based on this pressure value, the Control PCB makes calculations including for actuation of the PEEP valve V6.

  • Page 13: Ambient Pressure Conditions

    Fig. 3 Ventilation valve Ambient pressure Oxylog 2000 plus meters the tidal volume under BTPS conditions. Sensors conditions S7 and S9 measure the ambient pressure. S5 measures the current pressure level in the lung. In this way the Control PCB can balance fluctuating ambient pressure and the BTPS conditions (Body Temperature, Pressure, Saturated.

  • Page 14: Sensor Pcb

    Function description Oxylog 2000 plus Sensor PCB The Sensor PCB holds all the pressure sensors of the pneumatic system and the internal temperature gauge. The Sensor PCB is the interface for pressure measurement and valve actuation between the pneumatic and electronic sys- tems.
