11. Prima SP Anaesthetic Machine Range Service 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 regarding the servicing o

17. Always follow the procedures and checklist given in the instruction manual supplied with the vaporizer particularly when filling the vaporizer with anaesthetic agent WARNING Vaporizers must always be mounted never used free standing Free standing vaporizers may be accidentally tipped resulting in excessive and uncalibrated volumes of anaesthetic drug entering the breathing system Do not install or connect any vaporizer of any description between the CGO and the breathing system unless it is specifically designed for such use This allows the oxygen flush flow to pass through the vaporizer and severe overdosage may result 5 10 1 Selectatec Mounting System Dependent on choice of backbar manifold system up to two Selectatec compatible vaporizers may be fitted To install the vaporizer carefully offer the vaporizer up to the manifold Check that the gas connection ports on the vaporizer are aligned with the valves on the manifold Carefully lower the vaporizer onto the manifold and lock the vaporizer into position by clockwise rotation of the locking lever through 909 NOTE Do not use excessive force to lock the vaporizer onto the manifold Damage to the locking fastener will result CAUTION To prevent damage to the locking shaft ensure that the gas connection ports are aligned with the valves on the manifold and are correctly engaged before tightening the locking lever 5 10 2 Selectatec Compatible Vapor
