The UAM is a robust general anesthesia workstation that delivers anesthesia effectively wherever it’s installed. It blends continuous-flow and draw-over technologies to allow it to function indefinitely without power or compressed oxygen. It features an integrated oxygen concentrator to generate its own oxygen and provides standard connectors for cylinder, pipeline, and portable oxygen. If no electricity or external source of oxygen is available, the machine automatically draws in room air as the carrier gas. Its automatic ventilator provides electrically-driven ventilation in volume- and pressure-control modes, will operate without mains power for up to six hours on rechargeable battery, and comes with a manual ventilation option as a final safety measure.
