An anesthesia machine works by mixing gases and delivering them to the patient through a breathing circuit.
Main Components & Function:
1.Gas Supply System
•Connects to medical gases: O₂, N₂O, and air via cylinders or pipeline.
•Flow meters regulate the gas volume delivered to the patient.
2.Vaporizers
•Convert liquid anesthetic agents (like Isoflurane or Sevoflurane) into vapor.
•Mix the vapor with the fresh gas flow in accurate concentrations.
3.Breathing Circuit
•Delivers the gas mixture to the patient and removes CO₂ via absorbers.
•Can be used in manual, semi-automatic, or ventilator modes.
4.Ventilator (in advanced machines)
•Controls the patient’s breathing during surgery when they are unable to breathe spontaneously.
5.Monitoring & Safety Systems
•Built-in monitors for O₂ concentration, pressure, tidal volume, and agent levels.
•Alarm systems alert staff to leaks, blockages, or abnormal gas levels.
