K Penlon www ardusmedical com Prima SP Anaesthetic Machine Range User Manual Quality and Assurance in Anaesthesia THE IMPORTANCE OF PATIENT MONITORING WARNING Anaesthetic systems have the capability to deliver mixtures of gases and vapours to the patient which could cause injury or death unless controlled by a qualified anaesthetist There can be considerable variation in the effect of anaesthetic drugs on indi vidual patients so that the setting and observation of control levels on the anaesthesia systems does not in itself ensure total patient safety Anaesthesia system monitors and patient monitors are very desirable aids for the anaesthetist but are not true clinical moni tors as the condition of the patient is also dependent on his respiration and the functioning of his cardio vascular system IT IS ESSENTIAL THAT THESE ELEMENTS ARE MONITORED FREQUENTLY AND REGULARLY AND THAT ANY OBSERVA TIONS ARE GIVEN PRECEDENCE OVER MACHINE CONTROL PARAMETERS IN JUDGING THE STATE OF A CLINICAL PROCEDURE IMPORTANT Servicing and Repairs In order to ensure the full operational life of this anaesthetic machine servicing by a Penlon trained engineer should be undertaken periodically The machine must be serviced to the schedule detailed in section 8 Details of these operations are given in this Service Manual available only for Penlon trained engineers For any enquiry rega

127. ypoxic Device 3 5 1 Introduction The Mechanical AHD is housed within the flowmeter module and comprises a gear linkage between the oxygen control valve and a needle valve in the nitrous oxide flow The system is designed to control the relative flow rates of oxygen and nitrous oxide A predetermined minimum oxygen concentration of 30 3 in the oxygen nitrous oxide mixture is maintained over the flow range to ensure that a hypoxic mixture is not supplied from the anaesthetic machine 3 5 2 Gas Delivery Switch The Gas Delivery Switch A operates on the oxygen supply and must be in the On position for normal operation of the anaesthetic machine The switch consequently controls the supply of all gases provided with a gas cut off triggered by a predetermined pressure level within the oxygen supply see section 3 4 1 A whistle oxygen failure warning whistle will sound briefly whenever the gas delivery switch is turned on or off Note that the whistle functions normally if the oxygen supply fails see section 3 4 2 The switch also controls the electrical supply to the optional Flowmeter Lighting unit and O2 Monitor see section 3 13 2 3 5 3 Gear Linkage and Nitrous Oxide Control Valves A gear linkage connects the oxygen control knob on the flowmeter module and a needle valve in the nitrous oxide flow This linkage limits the flow of nitrous oxide relative to the flow of oxygen set by the user Note th
