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.
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.

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

Increase the slow rise time to minimise the initial spike (probably somewhere between 10 and 20) Decrease the F/S balance until the waveform is square. c) Using the insp. trailing edge adjustment controls, shape the trailing edge to reduce overshoot. d) Increase the exp leading edge, slow rise time control to minimize the overshoot on the fall waveshape.
14.12 Gas Fail Detection Verification a) With the air and oxygen hoses connected to separately controllable pressure sources Set the ventilator to CMV Gas inlet pressures to 4 Bar BPM: 60 Insp Time: 0.5 PIP: 30 mbar PEEP: 0 mbar b) Ensure there are no current alarm conditions.
14.13 Blender and Oxygen Monitoring Verification Ensure that the ventilator has been turned on and connected to air for 1 hour prior to carrying out the verification. Using a calibrated oxygen analyser, check the accuracy of the blender and the oxygen measurement throughout the range at the following ventilator mode settings.
100% O cell will need to be fitted. (This device is available from SLE on request, part number: L0291). Connect a standard patient circuit with test lung. Carry out a 100% oxygen calibration (One point) with the dummy 100% O cell.

62°C. DO NOT immerse any part of the ventilator in any liquid, with the exception of the expiratory exhalation block (SLE part No N6622). 20.1 Preparation of a new ventilator Remove all transit packaging. Inspect the fresh gas port and proximal airway port for any packing material.
• Unlock the exhalation block by turning the clamp through 90 degrees until it is horizontal. • Gently pull away the exhalation block and silencer from the gas ports. • Separate the silencer and exhalation block. Refitting the silencer and exhalation block is the reversal of removal. Do not force the exhalation block into place.
Ensure that the detergent solution does not enter the unit or the exhalation block gas ports on the side of the machine. (Touch Screen) Do not use any abrasive cleaners on the touch screen surface. Flow Sensor Wash in hand hot water/mild general purpose detergent solution (as prescribed by the appropriate hospital authority).
20.5 Sterilization method The silencer (N2186/01), flow sensor (N5201) and exhalation block (N6622) must be sterilized between use on patients. The ventilator cannot be sterilized. The exhalation block must be cleaned as an essential prerequisite to sterilization. For the silencer, flow sensor and exhalation block.

Appendix 5. VueLink Technical Data (Model C) Page 315...
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.
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.
34.4 Data transferred to the VueLink system from the SLE4000 The RS232 interface to the VueLink monitor enables the SLE4000 to send monitored patient data, ventilator settings, waveforms and alarms. Three digital waveforms are transmittable to the VueLink system, which are Pressure (AWP), Flow(AWF) and Tidal Volume(AWV).

The textual alarm messages on the VueLink system are brief summaries of the ventilator alarm conditions. The following table shows how the SLE4000 messages correspond to VueLink display messages.

40 seconds to start again. Only one alarm is condition is visible on the SPI at a time. As with the SLE4000, if there are several alarm conditions present then only the highest priority alarm will be displayed.
34.8 Activation of VueLink VueLink is activated by entering the activation code into the SLE4000/SLE4000 ventilator. To access the VueLink activation screen, goto the controller services panel within the user interface. Enter the code provided by SLE into the ventilator via the controller services panel to display the activation screen.
