Lung Protective Ventilation

The electronically controlled electrically driven piston ventilator technology of Atlan A350/XL anaesthesia machine helps to deploy lung protective ventilation measures that can be beneficial for perioperative lung function and may improve outcomes. ‒ Synchronised piston movement with the patient expiration flow reduces the expiratory resistance and can reduce work of breathing ‒ The set PEEP is maintained even in case of small leakage and during spontaneous breathing to reduce risk of atelectasis development ‒ High trigger sensitivity can detect even weak spontaneous breathing efforts of patients ‒ Fresh-gas decoupling ensures that changes to the fresh-gas flow have no influence on the applied tidal volume, ventilation pressures, and the accuracy of delivered VT even with very small VTs, e.g. down to 5 ml ‒ Features and functionalities optimise minimal- and low-flow application, which can contribute to improved humidity of anaesthetic gases, mucociliary clearance, maintenance of body temperature and reduced fluid loss. They include: – integrated active heating of breathing system to warm breathing gas and to reduce condensation – optimised breathing system architecture to enable fast changes in fresh-gas and agent concentrations – sample-gas recirculation to eliminate gas loss ‒ Lung recruitment maneuvers option* comprises one-step and multi-step recruitment methods, Insp./Exp. Hold function and reminder function to support recruitment manoeuvre deployment ‒ AutoFlow option ensures the delivery of the set tidal volume with the lowest required pressure to avoid pressure peaks and unintentional high tidal volumes ‒ Highly accurate APL valve with a nearly linear increase and decrease in pressure pattern
