Anesthesia Machine

Components:

Gas Sources: Medical gas cylinders (oxygen, nitrous oxide) and connections to hospital gas pipelines.

Pressure Reducing Valves: Reduce the pressure from the cylinders to a safe level for the machine.

Flowmeters: Allow precise control of the flow rates of different gases.

Vaporizers: Introduce volatile anesthetic agents (like isoflurane, sevoflurane) into the gas stream.

Breathing Circuit: Connects the machine to the patient, allowing for gas delivery and waste gas removal.

Ventilator: Controls the patient’s breathing, providing mechanical ventilation if needed.

Monitoring Systems: Display vital signs and other relevant information.

Scavenging System: Removes waste gases from the breathing circuit to prevent environmental contamination.

Function:

Gas Delivery:

The primary function is to precisely mix and deliver a gas mixture (oxygen, air, nitrous oxide, and inhaled anesthetic agents) to the patient through a breathing circuit.

Ventilation:

Modern anesthesia machines often incorporate a ventilator to assist or control the patient’s breathing during anesthesia.

Monitoring:

They also include monitors to track vital signs, including heart rate, blood pressure, oxygen saturation, and end-tidal carbon dioxide levels.
