  • Page 8: Introduction

    1. Introduction The SLE2000 is a constant flow, time cycle, and pressure limited neonatal ventilator with patient triggering. Main features are that it has no expiratory valve but uses a reverse flow of mixed gas that is injected from the exhaust manifold into the expiratory limb of the patient circuit. This flow of gas has the effect of compressing 5 LPM humidified gas into the patient ET tube.

  • Page 11: Warnings

    Do Not use oil or grease on oxygen fittings or where oxygen is used. The ventilator functional tests must be carried out each time the SLE 2000 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.

  • Page 41 The fresh gas transducer PTR2 is mounted in the electronic module and monitors the patient airway pressure. The SLE 2000 because of its unique principle of operation will ventilate the patient without the fresh gas supply. In order to ensure that the patient is always being supplied with fresh humidified gas, a restrictor is fitted in the patient fresh gas tubing close to inspiratory port of the ET connector.

  • Page 42: Fresh Gas System

    NV1, which is preset to 5LPM and supplies the fresh gas to the patient circuit via SV2 (high pressure dump solenoid) and a circuit preset pressure relief valve RV2. The SV2 bypass provides a continuous flow of 1LPM through the humidifier in the event of a high pressure dump. Page 42 (SLE2000)

  • Page 43: Cpap System

    Gas from AIR/OXYGEN Blender is supplied to the CPAP pressure regulator REG2 via the supply manifold. The output pressure of REG2 is fed to the CPAP nozzle in the expiratory manifold, and into the expiratory limb of the patient circuit to create the circuit CPAP pressure. (SLE2000) Page 43...

    Sounders should be functionally tested during periodic preventative maintenance and planned overhaul, refer to the service manual. The SLE2000 has 4 alarm sounders. All sounders are activated on power-up-self-test. During this test, the 4 sounders are turned off one at a time, together with their corresponding visual alarm indicators, in the following audio-visual test sequence.
  • Page 183 You should hear noticeable changes in loudness between the blocked and un- blocked port state. Switch OFF and ON the SLE2000, to repeat the audible test for each sound port in turn. Bear in mind that the power fail sounder will always be the loudest; and that the BZ2 sounder, which is driven with the lowest voltage, will sound slightly less loud than the others.
