This advanced Anesthesia Machine includes all the features of the standard model, with significant enhancements for extended surgical applications. It is equipped with a dual PA-I type vaporizer slot design, allowing for uninterrupted anesthesia delivery during long procedures and featuring interlocking tank capability for safe agent switching.
The Anesthesia Machine incorporates a high-precision dual infrared turbine flow sensor and differential pressure sensor for exceptional accuracy in gas flow measurement and ventilation control. The modular respiratory circuit is fully metallic, ensuring a reliable seal even under high-temperature disinfection, and simplifies maintenance and sterilization.
Like the standard version, this Anesthesia Machine includes comprehensive audible and visual alarms for parameters such as tidal volume, airway pressure, power failure, and oxygen failure. The oxygen failure safety system ensures that if oxygen pressure drops below 0.20 MPa, an alarm is triggered and N₂O supply is automatically halted. The backup power system provides seamless transition during power outages.
The advanced model also supports optional multi-parameter patient monitoring modules, allowing integration into a comprehensive Anesthesia Machine workstation. Additional features include an international-standard rotating Na-lime tank made of high-temperature-resistant PPSU (withstands up to 134°C), designed for rapid one-handed replacement. Optional accessories such as circuit heating, ACGO, and AGSS are available to customize the system for specific clinical needs.
