  • Page 8: Warnings And Cautions

    1. Warnings and Cautions 1.1 Warnings The electronic and pneumatic units of the SLE4000 infant ventilator are sealed at the factory with two Warranty Void If Label Broken seals. If the ventilator is subject to a warranty agreement do not attempt to carry out any procedure that would involve breaking these seals.

  • Page 9: Cautions

    The equipment is not suitable for use with, or in the presence of flammable anaesthetic mixtures. The SLE4000 flow monitoring system is calibrated to work in an air / oxygen mixture, the use of other gas mixtures may affect the flow monitoring accuracy of the ventilator.

  • Page 11 Principles of Operation (Model C) Page 11...

  • Page 12: Principles Of Operation

    2. Principles of Operation The SLE4000 infant ventilator consists of an electronic system in the upper section of the ventilator and a pneumatic system in the lower. 2.1 Electronic System The electronic system comprises three autonomous subsystems, one responsible for monitoring the patient, one responsible for controlling the valves of the pneumatic system and one for the user interface (touchscreen and displayed data).

  • Page 13: Pneumatic System

    2.2 Pneumatic System The pneumatic system comprises of the tubing and electro-mechanical valves necessary to provide the gas in conventional ventilation modes. The two gas controlling functions are blending and pressure generation 2.2.1 Blending The method used for blending air and oxygen in known proportions is to pressure regulate the two supplies (air and oxygen) so they produce equal flow rates and then allow each supply into a mixing chamber for a time period equivalent to the proportions required.

Item Nº: refers to the numbered part in the appropriate figure. An item number preceded by a dash (-20) is not illustrated.
  • Page 221 The Dot classification system. Items within the parts list have a dot prefix. The item with no dot as a prefix is the main assembly for that figure. Any item with one dot belongs to the main assembly. Any item with two dots is attached to the one dot item above it. (Three dot items are attached to two dot items etc).

    The module must be of the ‘Ventilator’ type. The cable from the M1032A module (Agilent part number: M1032-61654) requires the SLE VueLink adaptor (SLE part number: W0344) to connect it to the 9-pin RS232 socket on the back of the SLE4000 ventilator.

  • Page 317: Parameter Descriptions

    BPM on the VueLink system refers to pulse rate (beats per minute) whereas AWRR refers to airway respiratory rate. Therefore the names of parameters on the VueLink monitor are not the same as those on the SLE4000. A cross reference table follows.
