An anesthesia machine is a medical device used to administer anesthesia to patients during surgical procedures. It delivers a continuous flow of medical gases, such as oxygen and nitrous oxide, mixed with an accurate concentration of anesthetic vapors. Key components and features of an anesthesia machine typically include:br br 1. **Gas Supply**: Connects to sources of medical gases, such as oxygen and nitrous oxide, and regulates their flow.br br 2. **Flowmeters**: Measure and control the flow rate of each gas.br br 3. **Vaporizers**: Convert liquid anesthetics into vapors and allow for precise control of their concentration in the gas mixture.br br 4. **Breathing Circuit**: Delivers the gas mixture to the patient and removes exhaled gases. It usually includes hoses, a reservoir bag, and valves.br br 5. **Ventilator**: Assists or controls the patient's breathing, ensuring adequate ventilation during surgery.br br 6. **Scavenging System**: Collects and removes excess anesthetic gases to prevent contamination of the operating room environment.br br 7. **Monitoring Systems**: Track various patient parameters such as oxygen saturation, carbon dioxide levels, blood pressure, and heart rate to ensure patient safety.
