Anesthesia Machine Lab Report

To effectively perform or assist with a procedure, you must fully understand the anesthesia machine. It’s important to not only identify, but correctly and efficiently operate each of the machine’s components. In addition, you must understand the gas flow through the system, how to perform a pre-anesthetic check, also known as a pressure check, and how to care for and maintain this equipment. I will focus on a circle rebreathing system, it’s also the most common system. It contains a compressed gas supply, the anesthesia machine itself, and the breathing circuit. First, I will identify the machine as a whole system. The anesthetic machine’s function is to deliver volatile anesthetic gas to and from the patient. We need the combination of the compressed gas supply, breathing circuit, and the other machine parts to work together. The gas supply comes from the compressed gas cylinder and/or the tank. The tank has a pressure gauge and is held in a steal or aluminum cylinder. These tanks are flammable and supplied under extreme pressure, approximately 2200 psi, with varying volumes depending on the type of anesthesia machines we use. They attach to
Keeping the machine clean and dry is key to proper maintenance. You must change the Humid-vents monthly, they are placed between the ET tubes and the breathing tubes to removes the excess water. They help to keep the exhalation tube dry. Viral filters can be placed between exhalation valve and the exhalation tubes. This filter helps prevent the entrance of viruses into the machine and can be changed every two to three months. The gas cylinders should be inspected by the manufacture that we buy them from. As well as the pressure reducing valve and vaporizer should be inspected by them. Pressure gauges, manometers, flow meters, and flush valves should be checked for accuracy and proper
