Functions of an Anesthesia Machine

1. Gas Delivery: Ensures a consistent supply of oxygen, nitrous oxide, and/or air, mixed with anesthetic agents.
2. Ventilation: Controls the rate and volume of breaths delivered to the patient.
3. Monitoring: Continuously tracks the patient’s vital signs and adjusts the anesthesia accordingly.
4. Safety Alarms: Alerts the user in case of issues like low oxygen supply, high pressure, or equipment malfunction.

Safety Features

1. Oxygen Failure Alarm: Alerts when oxygen pressure falls below a certain level.
2. Interlock System: Prevents the simultaneous use of incompatible gases.
3. Hypoxic Guard: Ensures that a minimum level of oxygen is always mixed with the other gases.
4. Automatic Ventilator Cut-off: Stops mechanical ventilation if there’s a problem with gas delivery.
