Anesthesia machine Ilustración e icono

Anesthesia machine — an illustration of a modern anesthesia workstation used to deliver inhaled anesthetics and controlled ventilation during surgery. The device comprises multiple integrated modules—patient monitor with waveforms, breathing circuit with a blue reservoir bag, a yellow carbon dioxide absorber canister, vaporizers, flow/pressure controls, and drawers—forming a single perioperative system on caster wheels. In the structural hierarchy, these components function together within an operating room (OR) anesthesia delivery system. In the fields of anesthesiology, physiology, and biomedical engineering, it regulates fresh gas flow, vaporizes agents, removes carbon dioxide (CO2), and provides positive-pressure ventilation with oxygen (O2). Type: clinical equipment/medical device; site: hospital operating theatre. No human subjects are depicted.
