  • Page 8: Introduction

    1. Introduction The SLE2000 HFO ventilator is designed for use on neonates/infants. Its principle of operation is time cycled, pressure limited ventilation using a constant fresh gas flow. Main features are that it has no expiratory valve but uses a reverse flow of mixed gas that is injected into the expiratory limb of the patient circuit from the exhaust manifold.

  • Page 9: Principles Of Operation Sle 2000 Hfo

    1.1 Principles of Operation SLE 2000 HFO The patient circuit is supplied with a constant fixed flow of fresh gas at 5 litres per minute. This gas comes from the internally mounted Oxygen Blender and its concentration is monitored by a fuel cell and displayed on the FlO digital display.
  • Page 10 The same gas mixture from the Oxygen Blender is used to supply the patient Fresh Gas, CPAP, Inspiratory and Oscillation driving gas pressure. This avoids any possibility of dilution of the Fresh Gas mixture. There is a wave shape switch. This modifies the Driving Gas flow rate from the Solenoid valve through the nozzle and is used to slow down the rise time of the pressure waveform.

  • Page 12: Warnings

    The ventilator functional tests must be carried out each time the SLE 2000 HFO is used on patients. If any of these tests do not function as described then there is a problem and the ventilator must not be used until it is rectified.
