anaesthetic machine checklist aagbi

Before using any anaesthetic equipment, ventilator, breathing system or monitor, it is essential to be fully familiar with it. Anaesthetists must not use equipment unless they have been trained to use it and are competent to do so [4]. The continued presence of carbon dioxide cylinders on most of the anaesthetic machines in our hospital reflects a decision by the anaesthetic department to leave the cylinders in place for the members of the department who continue to use them. In the event of a change of anaesthetist during an operating session, the status of the anaesthetic equipment must be confirmed, including that a formal check has been performed. THEATRE:ANAESTHETIC MACHINE: Anaesthetic room/Theatre. Random Safety Auditing, Root Cause Analysis, Failure Mode and Effects Analysis. It should only be performed on basic ‘Boyle’s’ machines and it may be harmful to many modern anaesthetic workstations. Working off-campus? Intraoperative MRI. There were 21 pairs of checklists in which the same anaesthetist checked two machines in sequence. Circuit accessoire ou simplicité ne rime pas avec sécurité. A total of 133 checklists were completed, one of which was incomplete and was discarded. Switch on electrical supply (if appropriate). Compliance with the automated machine check. A Working Party was established in 2009 comprising Officers and Council Members of the AAGBI and representatives of the Group of Anaesthetists in Training (GAT), RCoA, MHRA and the British Association of Anaesthetic and Respiratory Equipment Manufacturers Association (BAREMA). This article is accompanied by an Editorial. Set the fresh gas flow to 5 l.min−1 and ventilate manually. Yes/No, 3.Does patient trolley tip head‐down?Yes/No. Magee P. The AAGBI produced a first set of guidelines on this area of practice in2009 [1]. Operate the emergency oxygen bypass control and ensure that flow occurs from the gas outlet without significant decrease in the pipeline supply pressure. To check the correct function of the oxygen failure alarm involves disconnecting the oxygen pipeline on some machines, whilst on machines with a gas supply master switch, the alarm may be operated by turning the master switch off. 2. A new, single‐use bacterial filter and angle piece/catheter mount must be used for each patient. Checklist for Anaesthetic Equipment 2012. However, this study found faults in the oxygen analyser in 11.3% of machine checks and other studies found the oxygen analyser to be absent or faulty in 25.4% and 55% of machine checks [7, 8]. 1.Is machine connected to an O2 supply?Yes/No, 3.Is machine connected to N2O supply (if intended for use)?Yes/No, 4.Are contents of spare N2O cylinder adequate?Yes/No, 5.Is machine connected to compressed air supply, 6.Are contents of spare air cylinder adequate?Yes/No, 7.Is CO2 cylinder attached to machineYes/No, 9.Are blanking plugs fitted to all empty cylinder yokes?Yes/No, 1.Do all flowmeter bobbins move freely throughout their, 2.With O2 flowing at 5 l/min, does O2 analyser approach, 1.When the O2 bypass control is operated, does flow occur, without significant drop in pipeline pressure? A clear note must be made in the patient’s anaesthetic record that the anaesthetic machine check has been performed, that appropriate monitoring is in place and functional, and that the integrity, patency and safety of the whole breathing system has been assured. This study follows up an initial audit in 1992 indicating that anaesthetic machine checking practices were often incomplete. This recommendation, by the Association of Anaesthetists, was the first development of the anaesthesia team concept. Note that excessive force during a ‘tug test’ may damage the pipeline and/or gas supply terminal. There are two new checklists – the first to be completed at the start of every operating session, the second a short set of checks before each case. Turn on the ventilator to ventilate the test lung. It is essential that anaesthetists have full training and formal induction for any machines they may use. Some anaesthetic workstations will automatically test vaporiser integrity. A two‐bag test should be performed after the breathing system, vaporisers and ventilator have been checked individually. 5. Confirm presence, size range and function of all ancillary equipment which may be needed. widely accepted standard for checking the anaesthetic machine and allied equipment in the modern operating theatre [1]. Open and close each vaporiser in turn. AAGBI SAFETY GUIDELINE Checking Anaesthetic Equipment 2012 Published by The Association of Anaesthetists of Great Britain and Ireland 21 Portland Place, London, W1B 1PY Telephone 020 7631 1650 Fax 020 7631 4352 [email protected] www.aagbi.org June 2012 This guideline was originally published in Anaesthesia. How to develop an effective obstetric checklist. A two‐bag test should be performed after the breathing system, vaporisers and ventilator have been checked individually [9]. Ensure that there are no leaks or obstructions in the reservoir bags or breathing system and that they are not obstructed by foreign material. An important consequence of this change is that Checklist 2 does not test the oxygen failure warning alarm in machines connected to pipeline oxygen. Attach the patient‐end of the breathing system (including angle piece and filter) to a test lung or bag. COVERS for anaesthetic machines: an audit and standard, The use of a checklist for anaesthetic machines. Anaesthetic machines have additional regulators and check valves to those shown above. A number of different faults in the analyser occurred; these are shown in Table 3. Manual leak testing of vaporisers was previously recommended routinely. With O2 flow of 5 l.min−1, occlude common gas outlet. The checklist specifies outcomes rather than processes and covers all the equipment necessary to conduct safe anaesthesia, not just the anaesthesia workstation. However, certain important changes have been introduced. Users must know the default setting for the machine in use. Is adequate pressure generated during the, 3.Does the pressure relief valve operate correctly when, 4.Is the disconnection alarm present and operating, 5.Is alternative means of ventilation available?Yes/No, 1.Is scavenging system correctly attached and functioning? A pre‐use check to ensure the correct functioning of anaesthetic equipment is essential to patient safety. Increased Resistance to Flow and Ventilator Failure Secondary to Faulty CO2 Absorbent Insert Not Detected During Automated Anesthesia Machine Check. 1.Are vaporisers for the required volatile agents present, correctly seated and locked to the back‐bar? All cylinders should be securely seated and turned off after checking their contents. Turn on each vaporiser in turn, and briefly occlude the, 6.Do any leaks occur from the filling ports of the vaporisers? 2012 Jun;67(6):571-4. doi: 10.1111/j.1365-2044.2012.07166.x. Inspection and Testing of Respirators and Anaesthesia Machines. Lest we forget: learning and remembering in clinical practice. For example, some modern anaesthetic workstations will enter a self‐testing cycle when the machine is switched on, in which case those functions tested by the machine … A record should be kept with the anaesthetic machine that these checks have been done. A quick ‘run‐through’ before the start of an operating session is not acceptable. Identify and take note of the gases that are being supplied by pipeline, confirming with a ‘tug test’ that each pipeline is correctly inserted into the appropriate gas supply terminal. Even when the presence of a carbon dioxide cylinder is not counted as a fault, faults were found in 30.3% of the machine checks in this study and the majority of these were potentially serious. The mean time taken to complete a check was 6.8 min and the mean time taken to complete two consecutive checks, in the anaesthetic room and operating theatre, was 12.7 min. 1). Careful note should be taken of any information or labelling on the anaesthetic machine that might refer to its current status. Reproduced with the kind permission of the Association of Anaesthetists of Great Britain and Ireland. Obstetric Anaesthetists' Association and Difficult Airway Society guidelines for the management of difficult and failed tracheal intubation in obstetrics. Check that adequate supplies of any other gases intended for use are available and connected as appropriate. No pre‐operative check can be exhaustive without becoming impracticable and the revised AAGBI guidelines aim to strike a compromise between safety and practicability. Check the whole breathing system is patent and the unidirectional valves are moving (if present). If nitrous oxide is to be used, the anti‐hypoxia device should be tested by first turning on the nitrous oxide flow and ensuring that at least 25% oxygen also flows. The anaesthetic machine has a label attached stating that it has recently been serviced. If you do not receive an email within 10 minutes, your email address may not be registered, For example, some modern anaesthetic work- An alternative source of oxygen should be readily available. Users must know which are included and ensure that the automated check has been performed. The Association of Anaesthetists of Great Britain and Ireland (AAGBI) developed a standardized checklist 1, 2 for checking anaesthetic machines and a laminated copy of the checklist should be attached to every anaesthetic machine to assist the anaesthetist checking the machine. Fifty‐five completed checklists were analysed; no problems developed during anaesthesia which were missed by the checklist. American Journal of Obstetrics and Gynecology. An anaesthetic machine (British English) or anesthesia machine (American English) is a medical device used to generate and mix a fresh gas flow of medical gases and inhalational anaesthetic agents for the purpose of inducing and maintaining anaesthesia.. Summary The use of the Association of Anaesthetists of Great Britain and Ireland checklist for anaesthetic machines, based on an oxygen analyser, was surveyed over a 5‐week period in a teaching hospital. Check that gas sampling lines are properly attached and free from obstruction or kinks. Where more than one vaporiser is present, turn each vaporiser on in turn and repeat this test. The aims were to ascertain if there has been any improvement during this period with special reference to the latest guidelines. Safety in MRI Units-an update 2010. These include bacterial filters, catheter mounts, connectors and tracheal tubes, laryngeal mask airways, etc. Perform a pressure leak test (between 20 and 60 cmH2O on the breathing system by occluding the patient‐end and compressing the reservoir bag. This new edition of the safety guideline updates the procedures recommended in 2004 and places greater emphasis on checking all of the equipment required. The most common type of anaesthetic machine in use is the continuous-flow which is designed to provide an accurate and continuous supply of medical gases (such as oxygen and nitrous oxide), mixed with an accurate concentration of anaesthetic vapour (such as isoflurane), and deliver this to the patient at a safe pressure and flow. Equipment faults may develop during anaesthesia that were either not present or not apparent on the pre‐operative check. Other studies have found the occurrence of faults to be at least as frequent as this [7, 8]. Any part of the breathing system, ancillary equipment or other apparatus that is designated ‘single‐use’ must be used for one patient only, and not reused. The poster presentations and checklists below, developed in the UK, are designed for use by the anaesthetist and anaesthetic assistant in addition to the WHO checklist: James B, Bryant H, Swales H and Al-Rawi S. Obstetric general anaesthetic safety checklist: guideline development through team simulation.
