The AR‑325B Anesthesia Machine

The AR‑325B Anesthesia Machine is a versatile and advanced system designed for both adult and pediatric patients, combining safety, precision, and modern monitoring capabilities. It operates with O₂ and N₂O gas sources at 0.27–0.55 MPa, supported by a multi‑range flow meter for O₂, N₂O, and Air, ensuring accurate gas delivery.

Safety is enhanced through its O₂/N₂O linkage and N₂O stopper system, which maintains oxygen concentration above 25% and automatically cuts off nitrous oxide flow if oxygen pressure drops below 0.2 MPa. The unit also provides a rapid oxygen supply function with a flow rate of 25–75 L/min for emergency use.

The AR‑325B supports two vaporizers (Halothane, Enflurane, Isoflurane, or Sevoflurane) as per customer requirements, and offers flexible respiratory circuit modes (all‑close, semi‑close, semi‑open). Its APL valve operates within 0.5–7 kPa, while respiratory bellows accommodate tidal volumes of 0–1500 ml for adults and 0–300 ml for children.

A 10.4” high‑definition TFT touch screen provides intuitive control, and ventilation modes include IPPV, SIPPV, SIMV, PEEP, MANUAL, SIGH, IMV, VCV, and PCV, with tidal volumes from 20–1500 ml. Integrated with a 12” patient monitor (ECG, RESP, NIBP, SpO₂, dual TEMP, PR/HR), and optional EtCO₂ and IBP modules, the AR‑325B delivers comprehensive anesthesia management with advanced monitoring and safety features, making it ideal for modern surgical environments.
