Breathing Systems Notes

It is made up of multiple components which include;  Fresh gas outlet This connects the breathing system to the anaesthetic machine  Breathing tubes These allow gas to travel to and from the patient  Reservoir bag This allows for visualisation of respiration, accumulation of oxygen and anaesthetic gases and provide a method of ventilation.  Adjustable pressure limiting (APL) valve Allows for safe connection to scavenging, releases waste gases, allows for control over and limits pressure build up  Scavenging Safe removal of anaesthetic gases  Unidirectional valves. Ensures gases flow the correct way and prevents fresh gas from mixing with waste gases.  Carbon dioxide absorbent Its purpose is to absorb expired carbon dioxide which then allows for complete rebreathing of exhaled gases.
