PowerPoint Presentation

[Audio] Good morning everyone. Today, we will be discussing the important topic of preventive maintenance and calibration for anaesthetic/anesthesia machines. We will be looking at popular brands and their calibration parameters for gas flowmeters, vaporizers, and ventilator functions. Our presenter today is RONEL WINSTON H VILLEGAS.,BMET III Quality Assurance and Laboratory Manager. Let's begin!.

[Audio] Preventive maintenance and calibration of Anaesthetic machines is an important topic to address. Avante, GE, Datex Ohmeda, Drager, Space Labs and Maquet are some of the popular anaesthetic machine brands, each offering their own unique features. To ensure the safety of those operating the machines, it's important to ensure they are maintained and calibrated according to manufacturer standards..

[Audio] An anaesthesia machine is essential for providing an accurately mixed gas of the desired composition to a breathing system during surgery. This combination of gases, usually composed of oxygen, nitrous oxide, and volatile anesthetic agents like isoflurane or desflurane, enables the patient to lose consciousness, remain still and pain-free, and be unable to remember what happened while under the influence of the gas. Knowing the basics of how an anaesthesia machine functions is important for ensuring the patient's safety..

[Audio] Preventive maintenance and calibration of an anesthesia machine is essential to guarantee patient safety. Tasks such as checking for potential leaks with soapy solution, inspecting all moving parts to ensure they move freely, checking all seals, connectors, adapters and parts are tight, noting any faults and regular removal of dust, dirt, water, waste matters and any tape and paper that may have entered the machine are all necessary. Making sure that all fittings, valves and wheels are clean from any dirt, replacing soda lime if it has changed color and replacing any deteriorated hoses and tubings are also important. By following these preventive maintenance tasks and reporting any faults to the technician immediately, you can ensure that your anesthesia machine remains in the best condition and any potential emergency can be avoided..

[Audio] We are discussing preventive maintenance and calibration of an anesthetic/anesthesia machine. Slide number 7 of this presentation covers the calibration of gas flowmeters, vaporizers, and ventilator functions. The importance of calibration and preventive maintenance for these components, how to establish a calibration program, and how to troubleshoot malfunctions of the machine components will be discussed..

[Audio] Begin by setting up the test analyzer to flowmeter calibration, connecting the test analyzer to the output port of the flowmeter, and setting a flow rate on the flowmeter before observing the test analyzer. Match the output value from the flowmeter and the test analyzer, recording the reading and writing it down on the calibration result..

[Audio] To ensure the accuracy of an anesthesia machine, it is important to adhere to the necessary preventive maintenance and calibration procedures. These procedures are necessary to regulate the flow rate of the devices that are used to distribute oxygen, which are governed by the ISO 15002 standards. As per these standards, for oxygen flow rates below 5 liters per minute, the flow rate should not deviate from the nominal value by more than 0.5 liters per minute. For oxygen flow rates above 5 liters per minute, the acceptable deviance should not exceed 10%. The temperature and atmospheric pressure conditions under which these evaluations need to take place are set at 23 degrees Celsius, plus or minus 2 degrees, and 1013 hectopascals respectively. Whilst the standards set by the Compressed Gas Association in North America are slightly different, they similarly specify an allowable error of 10% around the nominal value..

[Audio] To set up the test analyzer for vaporizer calibration, connect the output port or tubing's of the anesthesia machine to the input port of the test analyzer. Set the vaporizer to the desired set value. Observe the test analyzer and match the output reading of the anesthesia machine and the analyzer. Take note of the reading and record it on the calibration result..

[Audio] We're looking at the set-up of the ventilator function. To make sure the connections are correct, we must ensure they are as shown in the diagrams. Once this is done, we can observe the values our test analyzers display. This is an important step for preventive maintenance and calibration..

[Audio] Discussing the calibration parameters of a ventilator function is essential for a safe and efficient operation of an anesthesia machine. Certain parameters must be adjusted to meet the desired operating settings and ensure patient safety. This includes explaining the proper calibration of those parameters to ensure a successful operation of an anesthesia machine..

[Audio] The slide outlines the sample of tolerance or test limits for an anesthesia machine. It gives us a range of acceptable performance that the machine must pass in order to be safe and in full working order. It is essential to follow good maintenance practices and procedures to ensure the machine's reliability..

[Audio] When performing preventive maintenance and calibration on anaesthetic machines, it is important to consider the test limits or tolerances. These refer to the difference between the measured value and the reference value, and if these values exceed the prescribed range, corrective maintenance should be performed. Following the tolerance or test limits of the machine helps ensure the user's safety and the device's functionality..
